A metal deficient early B-type star near the edge of the galactic disk.
SMARTT S.J., DUFTON P.L. and ROLLESTON W.R.J.
Abstract (from CDS):
High resolution spectra of an early B-type star associated with the H II region detected by de Geus et al. (1993ApJ...413L..97D) are analysed using LTE model atmosphere techniques to derive stellar atmospheric parameters and a chemical composition. A distance to the star of 8.2kpc is estimated, placing it near the edge of the galactic disk and closer than the kinematic distance of 20kpc to the H II region, calculated by de Geus et al. A differential line by line abundance analysis with respect to the spectroscopic standard τ Sco indicates a significant metal depletion, with elements down on average by -0.5dex.
