Spectral analysis of four surprisingly similar hot hydrogen-rich subdwarf O stars
M. Latour, P. Chayer, E. M. Green +2
We perform a comprehensive spectroscopic analysis of four such bright sdO stars, namely Feige 34, Feige 67, AGK81 266, and LS II18 9, among which the first three are used as…
Observations of the Ultraviolet-Bright Star Y453 in the Globular Cluster M4 (NGC 6121)
William V. Dixon, Pierre Chayer, Marilyn Latour +2
We present a spectral analysis of the UV-bright star Y453 in M4. Model fits to the star's optical spectrum yield T_eff ~ 56,000 K. Fits to the star's FUV spectrum, obtained with th…
Blue large-amplitude pulsators as a new class of variable stars
P. Pietrukowicz, W. A. Dziembowski, M. Latour +13
Regular intrinsic brightness variations observed in many stars are caused by pulsations. These pulsations provide information on the global and structural parameters of the star. T…
