Orion's Belt 2009-01-29.jpg

Mintaka, located in the constellation of Orion, is one of the three brightest stars that make up Orion’s belt. Mintaka can be found on the western side of the belt.

Mintaka, also known as δ Orionis, 34 Orionis, 88 G. Orionis, FK5 206, Hips 25930, 4134 AD, CCDM J05320-0018, and WDS J05320-0018.

Mintaka / ˈmɪntəkə /, [13] is the name given to a star system known as Orion delta (δ Orionis, abbreviated as Delta Ori, δ Ori) and 34 Orionis (34 Ori). It is located about 1200 light-years away from the sun in the Orion constellation. Along with Alnitak (Zeta Orionis) and Alnilam (Orion’s Epsilon), these three stars make up Orion’s Belt, which has been referred to by various names in ancient cultures. Mintaka is positioned very near the celestial equator. When Orion is close to the meridian, Mintaka can be seen as the rightmost star of the Belt when observed from the Northern Hemisphere facing south.

Nomenclature

Orion Delta is a celestial object known as 34 Orionis according to the Bayer designation. It is also referred to as Mintaka, a name derived from the Arabic word for “belt” – منطقة or Manṭaqa. [14] In the year 2016, the International Astronomical Union established the Working Group on Stellar Names (WGSN) [15] with the purpose of categorizing and standardizing proper names for stars. The first bulletin of the WGSN, released in July 2016, [16] featured a table containing the initial two sets of names approved by the WGSN, which included Mintaka (Mintaka) for this specific star. Consequently, it has been included in the IAU Catalog of Stellar Names. [17]

Observational history

The position of the δ star in Orion’s belt (circled) is depicted on a standard star chart that focuses on the southern or upper sky when viewed from northern latitudes. In the Southern Hemisphere, the star is typically seen on the left when looking towards the northern sky.

Mintaka, one of the three stars in Orion’s belt, is located in the westernmost position. It is easily visible without the aid of a telescope, being one of the most luminous stars in the celestial sphere, and has been documented since ancient times.

Star System

δ Orionis is a star system with multiple stars. There are two stars with a magnitude of 7 located about 52 arc seconds away from the main star, which has a magnitude of 2. In between these stars, there is another star that is much dimmer. This star system is known as WDS 05320-0018 in the Washington Double Star Catalog. The companion star, which has a magnitude of 14, is listed as component B, and the star with a magnitude of 7 is listed as component C. [20]

The main component of this system is a triple system. It consists of a bright giant star with a classification of O9.5 and a main sequence star with a classification of B. These two stars orbit each other every 5.73 days and occasionally show minor eclipses when the brightness of the system decreases by about 0.2 stellar magnitude. Additionally, there is a subgiant star with a classification of B that can be resolved at a distance of 0.26 inches. [3] During a primary eclipse, the apparent magnitude of the entire system drops from 2.23 to 2.35, while during a secondary eclipse it only drops to 2.29. [21]

The companion star, HD 36485, is a B-type main-sequence star with peculiar chemical properties. It is a double star with an A-type companion that orbits it in 30 days. The star’s spectrum is unique, showing H-alpha emission and a strong absorption line of helium. It also has a powerful magnetic field and rotates at a very slow speed, causing a stratification of its atmosphere and resulting in the unusual spectrum observed. [8]

The companion star, which has a magnitude of 14, is believed to be located at a similar distance to HD 36485. It is slightly cooler and less luminous than the Sun. [11]

Mintaka is surrounded by a group of faint stars, which may be part of the cluster that surrounds σ Ori. [22]

Distance

The distance is calculated based on the parallax of the Hipparcos satellite, which is 212 ± 30 pc. However, when comparing the spectral distances, similar stars, and cluster membership, it suggests a distance that is more than twice the value obtained from the satellite. This discrepancy is not unique to Mintaka and the reasons behind it are still unclear. In the Gaia 2 Data Release, components B and C have parallaxes of 3.4531 ± 0.0371 mas and 2.5727 ± 0.0767 mas, respectively, indicating much larger distances than the main source obtained from Hipparcos.

Origin and cultural importance

Astrologers believed that Mintaka was an omen of good luck. [14]

The belt of Orion

The three stars of the Belt in the constellation of Orion have been given various names throughout different cultures. Some Arabic terms for these stars include Al Nijad which means ‘Belt’, Al Nasak which means ‘line’, and Al-Alqat which translates to ‘Golden grains or nuts’. In modern Arabic, they are referred to as Al Mizan al Shaqq which means “A ray of precise scale”. In Chinese mythology, they were also known as a weight beam. [ citation needed ]

In Chinese, the term 參 宿 (Sheng So), which means ‘Three stars (asterism)’, is used to refer to the asterism consisting of Mintaka, Alnilam, and Alnitak (Orion’s Belt). Later on, Betelgeuse, Bellatrix, Saif, and Rigel were added to this group. [25] Therefore, the Chinese name for Mintaka is 參 宿 三 (Shen S san), which translates to ‘the third star of three stars’ in English. [26] This asterism is considered one of the western mansions of the white tiger.

Mintaka, also known as Delta Orionis (δ Orionis, abbreviated Delta Ori, δ Ori) and 34 Orionis (34 Ori), is a multiple star situated approximately 1200 light-years away from the Sun in the constellation Orion. Alongside Alnitak (Zeta Orionis) and Alnilam (Epsilon Orionis), these three stars create Orion’s Belt, which holds different names in various ancient cultures. Mintaka is positioned in close proximity to the celestial equator. When Orion is near the meridian, Mintaka is the rightmost star of the Belt when observed from the northern hemisphere, facing south.

Nomenclature

The star known as Orion Delta is designated as 34 Orion in the Flemsteed system. The name Mintaka is derived from the Arabic word “manṭaqa,” which means “belt.” In 2016, the International Astronomical Union established the Working Group on Star Names (WGSN) to create a standardized catalog of proper names for stars. The first bulletin of the WGSN, released in July 2016, included a table of the initial two groups of names endorsed by the WGSN, which featured Mintaku as the name for this particular star. As a result, Mintaku is now officially listed in the IAU Catalog of Star Names.

Orion’s δ can be found in the southern or upper sky when looking from northern latitudes, as indicated on a regular star chart. In the Southern Hemisphere, it typically appears to the left when observing the northern sky.

Mintaka, one of the three stars in Orion’s belt, is located in the westernmost position. It is easily visible without the use of a telescope and is renowned as one of the brightest stars in the night sky, recognized since ancient times.

In 1900, Henri-Alexandre Deslandres conducted radial velocity measurements at the Paris Observatory. These measurements revealed that Mintaka has a variable radial velocity, indicating that it is spectrally double. However, Deslandres’ initial estimate of an orbital period of 1.92 days was proven incorrect in 1904 by Johannes Franz Hartmann. Hartmann used photographic plates taken at the Potsdam Observatory and determined that the actual orbital period is 5.7 days. Additionally, Hartmann observed that the calcium K line at 393.4 nm in the stellar spectrum does not exhibit periodic line shifts caused by the star’s orbital motion. He proposed that this discrepancy is due to the presence of a calcium-containing cloud along the line of sight to Mintaka. This groundbreaking observation marked the first detection of an interstellar medium.

The star system

δ Orion is a system consisting of multiple stars. There is a star with a magnitude of 7 located at a distance of 52 angular seconds from a second magnitude star, with a much dimmer star positioned in between them. This particular system is known as WDS 05320-0018 in the Washington Double Star Catalog, with the 14th magnitude companion identified as component B and the seventh magnitude star designated as component C.

The seventh-magnitude companion, HD 36485, is a chemically peculiar B-type main-sequence star. It is also a spectral double star, with a faint A-type companion in a 30-day orbit. What makes this star stand out is its unusual spectrum, which exhibits H-alpha emission and notably strong helium absorption lines. Additionally, it possesses a strong magnetic field and rotates at a very slow velocity, leading to chemical stratification in its atmosphere. These factors contribute to the unique abundances observed in its spectrum.

The 14th magnitude companion is believed to be located at approximately the same distance and is a star slightly cooler and less bright than the Sun.

Mintaka is surrounded by a group of faint stars, which may be part of the cluster surrounding σ Ori.

Distance

The distance calculated from the Hipparcos parallax satellite is 212 ± 30 pc, while spectral distances, comparisons with similar stars, and cluster membership suggest a value more than double that. This kind of unresolvable discrepancy is not unique to Mintaka, and the reasons behind it are still to be clarified. In Gaia Data Release 2, components B and C are listed with parallaxes of 3.4531 ± 0.0371 msd and 2.5727 ± 0.0767 msec, respectively, indicating distances much greater than the value derived from Hipparcos for the star.

Origin and cultural importance

Ancient astrologers believed that Mintaka symbolized positive outcomes and good luck.

The Three Stars of Orion

Dunhuang Star Atlas – Orion

The three stars of Orion’s belt have been known by various names in different cultures. In Arabic, they are referred to as Al Nijād “The Belt”, Al Nasak “The Line”, Al Alkāt “Golden Grains or Nuts”, and in modern Arabic, Al Mīzān al H – akk “The Ray of the Exact Scale”. In Chinese mythology, they are also known as the Scale Beam.

In Chinese, 參 宿 (Shēn Sù), meaning Three Stars (asterism), refers to the group of stars consisting of Mintaka, Alnilam, and Alnitak (Orion’s Belt), with Betelgeuse, Bellatrix, Saif, and Rigel later added. Therefore, the Chinese name for Mintaka is 參 宿 三 (Shēn Sù sān, English: Third star of three stars). It is considered one of the mansions of the White Tiger in Western astrology.
