Spectral analysis of 636 white dwarf - M star binaries from the Sloan Digital Sky Survey
René Heller, Derek Homeier, Stefan Dreizler +1
We present a catalog of 857 white dwarf (WD)-M binaries from the sixth data release (DR6) of the Sloan Digital Sky Survey (SDSS), most of which were previously identified. For 636…
Time-series Spectroscopy and Photometry of the Pulsating Subdwarf B Star PG 1219+534 (KY UMa)
M. D. Reed, J. R. Eggen, S. L. Harms +7
We present observations and analysis of time-series spectroscopy and photometry of the pulsating subdwarf B star PG 1219+534 (KY UMa). Subdwarf B stars are blue horizontal branch s…
Towards Asteroseismology of PG1605+072
A. Tillich, U. Heber, S. J. O'Toole +2
We present our attempt to characterise the frequency spectrum of the bright V 361 Hya star PG1605072 from atmospheric parameter and radial velocity variations through a spectros…
An evolutionary study of the pulsating subdwarf B eclipsing binary PG1336-018 (NY Vir)
H. Hu, G. Nelemans, R. Østensen +3
The formation of subdwarf B (sdB) stars is not well understood within the current framework of stellar single and binary evolution. In this study, we focus on the formation and evo…
The MSST Campaign: II.Effective temperature and gravity variations in the multi-periodic pulsating subdwarf B star PG1605+072
A. Tillich, U. Heber, S. J. O'Toole +2
Stellar oscillations are an important tool to probe the interior of a star. Subdwarf B stars are core helium burning objects, but their formation is poorly understood as neither si…
The binary properties of the pulsating subdwarf B eclipsing binary PG 1336-018 (NY Vir)
M. Vučković, C. Aerts, R. Østensen +5
We present an unbiased orbit solution and mass determination of the components of the eclipsing binary NY Vir as a critical test for the formation scenarios of subdwarf B stars. We…
