2010年11月1日 · We examine a stochastic mechanism by comparing amplitude variations with simulated stochastic data. We also use the binary nature of KPD 1930+2752 for identifying pulsation modes via multiplet structure and a tidally-induced pulsation geometry.

KPD 1930+2752 is a binary star system including a subdwarf B star and a probable white dwarf with relatively high mass. [6]

1999年8月2日 · We report additional photometric CCD observations of KPD 0422+5421, a binary with an orbital period of 2.16 hours which contains a subdwarf B star (sdB) and a white dwarf. There are two main results of this work.

2005年10月28日 · We present the analysis of 200 high-resolution and 150 low-resolution spectra of the pulsating subdwarf close binary KPD 1930+2752 obtained with the Keck and the Calar Alto 2.2 m telescopes.

KPD 1930+2752 is a pulsating subdwarf B star with a particularly rich period spectrum, likely due to significant rotational splitting. It is also a short period (~ 2h17m), close binary system (as revealed by the presence of an ellipsoidal variation in the light curve) containing an unseen companion - almost certainly a white dwarf.

KPD 1930+2752 is a pulsating subdwarf B star with a particularly rich period spectrum, likely due to significant rotational splitting. It is also a short period (∼ 2h17m), close binary system (as revealed by the presence of an ellipsoidal variation in the light curve) containing an unseen companion – almost certainly a white dwarf.

KPD 1930+2752 is the first star to be discovered that is a good candidate for the progenitor of a Type Ia supernova of this type, which will merge on an astrophysically interesting time-scale.
