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…
