| Abstract: |
A search is presented for stars that may have formed coevally with the apparently young halo star PHL 346. Candidates were selected for spectroscopy from UBR Schmidt Telescope plates scanned with the COSMOS facility at the Royal Observatory, Edinburgh. Spectroscopic observations at 3.5 Angstroms resolution were made of 72 field stars using the 1.9m telescope at the South Africa Astronomical Observatory; 16 A- and B-type stars were found, one of which had the appropriate spectral type and radial velocity to be associated with PHL 346. Further photometry and spectroscopy confirmed this identification. The remaining low gravity early-type stars have a mean LSR radial velocity of --75 kms(-1) , consistent with a non-rotating halo population. |
