On the rotation properties of a post-explosion helium-star companion in Type Iax supernovae
Yaotian Zeng, Zheng-Wei Liu, Xiangcun Meng +1
Recent studies have suggested that type Iax supernovae (SNe Iax) are likely to result from a weak deflagration explosion of a Chandrasekhar-mass white dwarf in a binary system with…
Long-term evolution of post-explosion Helium-star Companions of Type Iax Supernovae
Yaotian Zeng, Zheng-Wei Liu, Alexander Heger +3
Supernovae of Type Iax (SNe Iax) are an accepted faint subclass of hydrogen-free supernovae. Their origin, the nature of the progenitor systems, however, is an open question. Recen…
The Common Envelope Evolution Outcome -- A Case Study on Hot Subdwarf B Stars
Hongwei Ge, Christopher A Tout, Xuefei Chen +6
Common envelope evolution (CEE) physics plays a fundamental role in the formation of binary systems, such as mergering stellar gravitational wave sources, pulsar binaries and type…
Signatures of a surviving helium-star companion in Type Ia supernovae and constraints on the progenitor companion of SN 2011fe
Zheng-Wei Liu, Friedrich K. Roepke, Yaotian Zeng
Single-degenerate (SD) binary systems composed of a white dwarf and a non-degenerate helium (He)-star companion have been proposed as the potential progenitors of Type Ia supernova…
