| Description | The star OH 345.0+15.7 (AFGL source GL 1822; IRAS 16029-3041) is an OH (hydroxyl) line emitter and has no optical counterpart. It is likely a late M-type star with a very dense dusty circumstellar envelope at a distance of about 6 kpc (19600 light years) from us. It is losing its mass at a rate of 1.4 x 10-4 solar masses per year, implying that it is in a superwind phase at the tip of the asymptotic giant branch (Persi et al. 1990, A&A, 237, 153). The wind is moving out from the star at about 13 km/sec. Persi et al. in 1985 June found a K magnitude of 6.82 for the star (the 2MASS Ks magnitude is 6.87 ± 0.02; the 2MASS color is J-Ks=8.72). The OH/IR star is likely nearing the end of its life. The red "stars" trailing to the south in decreasing brightness are ghost artifacts of the bright OH/IR star. |
