Shell helium-burning hot subdwarf B stars as candidates for blue large-amplitude pulsators
H. Xiong, L. Casagrande, X. Chen +7
Blue large-amplitude pulsators (BLAPs) are a newly discovered type of variable star. Their typical pulsation periods are on the order of a few tens of minutes, with relatively larg…
Subdwarf B stars from the common envelope ejection channel
H. Xiong, X. Chen, P. Podsiadlowski +2
From the canonical binary scenario, the majority of sdBs are produced from low-mass stars with degenerate cores where helium is ignited in a way of flashes. Due to numerical diffic…
A progenitor binary and an ejected mass donor remnant of faint type Ia supernovae
S. Geier, T. R. Marsh, B. Wang +17
Type Ia supernovae (SN Ia) are the most important standard candles for measuring the expansion history of the universe. The thermonuclear explosion of a white dwarf can explain the…
Common Envelope Evolution: Where we stand and how we can move forward
N. Ivanova, S. Justham, X. Chen +16
This work aims to present our current best physical understanding of common-envelope evolution (CEE). We highlight areas of consensus and disagreement, and stress ideas which shoul…
Some constraints on the lower mass limit for double-degenerate progenitors of Type Ia supernovae
Xuefei Chen, Jeffery C. Simon, Xianfei Zhang +1
Recent theoretical and observational studies both argue that the merging of double carbon-oxygen white dwarfs (WDs) is responsible for at least some Type Ia supernovae (SNe Ia). Pr…
The helium star donor channel for the progenitors of type Ia supernovae and their surviving companion stars
Bo Wang, Zhanwen Han
The nature of type Ia supernovae (SNe Ia) is still unclear. Employing Eggleton's stellar evolution code with the optically thick wind assumption, we systematically studied the He s…
