Spectroscopy of hot stars in the halo
Listed in IVOA Registry (Virtual Observatory)
We discuss a spectroscopic and photometric technique that enables the identification and classification of field horizontal-branch (FHB) and other A-type stars, even from relatively low signal-to-noise ratio medium-resolution spectra.
Description
This technique makes use of broadband UBV colors predicted from model atmosphere calculations and Balmer line profiles and Ca II K equivalent widths determined from synthetic spectra to estimate the physical parameters T_eff_, log(g), and [Fe/H] for stars in the effective temperature range 6000 - 10,000 K.
