The effects of diffusion in hot subdwarf progenitors from the common envelope channel
Conor M. Byrne, C. Simon Jeffery, Christopher A. Tout +1
Diffusion of elements in the atmosphere and envelope of a star can drastically alter its surface composition, leading to extreme chemical peculiarities. We consider the case of hot…
A pulsation zoo in the hot subdwarf B star KIC 10139564 observed by Kepler
A. S. Baran, M. D. Reed, D. Stello +13
We present our analyses of 15 months of Kepler data on KIC 10139564. We detected 57 periodicities with a variety of properties not previously observed all together in one pulsating…
Angular momentum transfer between oscillations and rotation in subdwarf B hybrid pulsators
Fernando Pérez Hernández, Raquel Oreiro, Haili Hu
Context. Subdwarf B pulsators exhibit pressure (p) and/or gravity (g) modes. Their frequency spectra range from very simple, with few frequencies, to very rich, with more than fift…
Iron and nickel diffusion in subdwarf B stars
Haili Hu
Pulsations in subdwarf B stars are attributed to radiative levitation of iron-group elements in the stellar envelope. Until now, only iron diffusion is accounted for in stellar mod…
Slowing down atomic diffusion in subdwarf B stars: mass loss or turbulence?
Haili Hu, Christopher A. Tout, Evert Glebbeek +1
Subdwarf B stars show chemical peculiarities that cannot be explained by diffusion theory alone. Both mass loss and turbulence have been invoked to slow down atomic diffusion in or…
Gravitational settling in pulsating subdwarf B stars and their progenitors
Haili Hu, E. Glebbeek, A. A. Thoul +4
Diffusion of atoms can be important during quiescent phases of stellar evolution. Particularly in the very thin inert envelopes of subdwarf B stars, diffusive movements will consid…
