J/ApJ/818/202          Hot subdwarf stars in LAMOST DR1             (Luo+, 2016)

Hot subdwarf stars observed in LAMOST DR1--Atmospheric parameters from single-lined spectra. Luo Y.-P., Nemeth P., Liu C., Deng L.-C., Han Z.-W. <Astrophys. J., 818, 202 (2016)> =2016ApJ...818..202L (SIMBAD/NED BibCode)
ADC_Keywords: Stars, subdwarf ; Surveys ; Spectroscopy Keywords: catalogs - subdwarfs - surveys - techniques: spectroscopic Abstract: We present a catalog of 166 spectroscopically identified hot subdwarf stars from LAMOST DR1, 44 of which show the characteristics of cool companions in their optical spectra. Atmospheric parameters of 122 subdwarf stars with non-composite spectra were measured by fitting the profiles of hydrogen (H) and helium (He) lines with synthetic spectra from non-LTE model atmospheres. A unique property of our sample is that it covers a large range in apparent magnitude and galactic latitude, therefore it contains a mix of stars from different populations and galactic environments.
