p-mode-dominated subdwarf B pulsators in binaries
This paper presents spectroscopic and seismic analyses of two rare hybrid pulsating subdwarf B (sdB) stars, PG 0048+091 and PG 1315-123, which are dominated by pressure (p)-mode... -
GALEX survey subdwarf atmospheric parameters
We present an update of our low-resolution spectroscopic follow-up and model atmosphere analysis of hot subdwarf stars from the Galaxy Evolution Explorer (GALEX) survey. Targets... -
KPD UV-excess objects
A survey for ultraviolet-excess objects has been performed for over about 1000sq.deg of the Galactic plane. Photographic blue and ultraviolet plates were obtained to select... -
Radius relations for low-metallicity M-dwarf stars
M subdwarfs are low-metallicity M dwarfs that typically inhabit the halo population of the Galaxy. Metallicity controls the opacity of stellar atmospheres; in metal-poor stars,... -
Discovery of new TESS pulsating hot subdwarfs
This work is dedicated to a search for new pulsating hot subdwarfs in TESS photometric data which could have been missed in previous searches. By matching catalogues of hot... -
Catalogue of hot subdwarf stars DR2
In light of substantial new discoveries of hot subdwarfs by ongoing spectroscopic surveys and the availability of new all-sky data from ground-based photometric surveys and the... -
Radial velocity curve of Balloon 090100001
We have obtained 2552 useful low-resolution spectra of the bright sdBV Balloon 090100001, which form the first large time-resolved spectroscopic dataset of this brightest known... -
Stellar parameters for 134 cool subdwarfs
The results of a search for cool subdwarfs are presented. Kinematic (U, V, and W) and stellar parameters (Teff, logg, [Fe/H], and Vturb) are derived for 134 candidate subdwarfs... -
Probing the LHS Catalog
We present moderate resolution spectroscopy of 111 cool dwarf stars to supplement the observations we have already presented in the Palomar/MSU Nearby-Star Spectroscopic Survey....
