Journal ArticleDOI
Pulsations in hot subdwarf stars: recent advances and prospects for testing stellar physics
Stéphane Charpinet,Valérie Van Grootel,Gilles Fontaine,Pierre Brassard,Suzanna K. Randall,Elizabeth M. Green +5 more
TL;DR: In this article, the most recent advances in hot subdwarf asteroseismology have been presented and hints of the foreseen future achievements of hot sub-drwarfs are provided.
Journal ArticleDOI
Studies of hot B subdwarfs. II - Energy distributions of three bright sdB/sdOB stars in the 950-5500 A range
TL;DR: Voyager ultraviolet spectrometer observations of the subdwarf B or OB stars HD 205805, UV 1758+36, and Feige 66 are presented in this paper.
Journal ArticleDOI
Just how hot are the ω Centauri extreme horizontal branch pulsators
M. Latour,Suzanna K. Randall,Pierre Chayer,Gilles Fontaine,Annalisa Calamida,Justin Ely,Thomas M. Brown,W. B. Landsman +7 more
TL;DR: In this article, a spectral analysis of two rapidly pulsating extreme horizontal branch (EHB) stars found in ω Cen is presented, which places the stars below the red edge of the theoretical instability strip in the log g −T eff diagram, where no pulsation modes are predicted to be excited.
Book ChapterDOI
The Potential of Asteroseimology for Hot, B Subdwarfs: A New Class of Pulsating Stars?
TL;DR: In the last two decades, considerable progress has been made in our understanding of the physical properties and evolutionary status of hot, hydrogen-rich subdwarfs B stars as discussed by the authors, and it is now currently believed (eg, Heber et al 1984) that sdB stars are ~ 05 M ⊙ objects belonging to the so-called extended horizontal branch (EHB) which never evolve toward the asymptotic giant branch (AGB) after core helium exhaustion.
