It is also an infra-red source. It is a member of the Pleiades Group. From James Kaler's Star Notes: Elnath has positional significance, as it is in the Milky Way only three degrees to the west of the anticenter of the Galaxy, the point directly opposite the Galactic Center in Sagittarius. In this broad direction lie vast dark cold clouds of interstellar gas and dust in which stars are being born. Physically, Elnath is a hot (13,600 Kelvin) class B giant star. The radius derived from temperature and luminosity, 4.6 times that of the Sun, agrees well that found from the original measurement of angular diameter, though not with a more recent measure, which makes the star 35 percent larger, showing the difficulty of such observations. Like so many stars of its class, Elnath is "chemically peculiar" and appears to be a "mercury-manganese" star, the manganese abundance 25 times normal, the calcium and magnesium abundance reduced and only an eighth solar. These peculiarities are caused by the combined action of gravity and radiation, which make the atoms of some elements drift downward and out of sight and others rise. Elnath has a mass of around 4.5 times that of the Sun. It is beginning to die, and if it has not already completely shut down the fusion of hydrogen in its core, it will before too long. Within only a couple million years, it will expand to become a cooler orange giant star. - 19 - Zone 111 Double Stars Easy STF 645 Bur 1047; ADS 3730; HD 33204; SAO 76990 Position: 0510+2802 A B C BC Magnitude 5.93 8.62 9.60 Separation PA — — 12.4 + 24 0.4 75 Rating: 2 E Year — 1991 Spectra A5m A3 Colors W W No 1889 Notes: AB 1829: 11.7 @ 27. 46 measurements.
