Rotational broadening and conservation of angular momentum in post-extreme horizontal branch stars
Gilles Fontaine,M. Latour +1 more
TL;DR: In this article, it was shown that angular momentum conservation in uniformly rotating structures (rigid-body rotation) boosts that value of the projected equatorial rotation speed by a factor of 3.6 by the time the model has reached the region of the surface gravity-effective temperature plane where the newly-studied post-EHB objects are found.

Observational Asteroseismology of Hot Subdwarf Stars with the Mont4K/Kuiper Combination at the Steward Observatory Mount Bigelow Station
Gilles Fontaine,Elizabeth M. Green,Stéphane Charpinet,M. Latour,Suzanna K. Randall,Valérie Van Grootel,Pierre Brassard +6 more
TL;DR: In this paper, the authors carried out several extensive observational campaigns on pulsating hot subdwarf stars using the Mont4K CCD camera attached to the 1.55 m Kuiper Telescope on Mount Bigelow.

FUSE Observations of the Peculiar Hot SDO Star MCT 0019-2441
TL;DR: In this article, the photospheric abundance patterns of a dozen chemical species with T eff in hot B and OB subdwarfs were mapped for the star MCT 0019-2441, which was selected to help map the hot end of the effective temperature of sdB and sdOB stars.
Journal ArticleDOI
Modelling compact pulsators
TL;DR: In this article, a theoretical understanding of the observed instability strips as well as the details of the driving mechanism at work for each type of pulsator is discussed. But the authors focus on the particularly successful case of rapidly pulsating subdwarf B (EC 14026) stars.
Book ChapterDOI
On the Interpretation of the dP/dt Measurement in G117-B15A
TL;DR: The measurement of a rate of period change in the pulsating DA white dwarf G117-B15A reported by Kepler at this Workshop (Kepler et al 1991) is both an exciting and important result since it potentially allows us to infer, for the very first time, the core composition of a white dwarf.
