A Helium-shell Burning Blue Horizontal Branch Star Produced from Common Envelope Evolution
Jiao Li, Changqing Luo, Hai-Liang Chen +16
Observationally, blue horizontal branch (BHB) stars are defined as hot stars occupying a characteristic region between the extreme blue horizontal branch and RR Lyrae variables in…
Revisiting atmospheric Roche lobe overflow in symbiotic binaries
Tan Liu, Natalia Ivanova, Philipp Podsiadlowski +5
Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios, leading to a common envelope. However, many observed S-type s…
Supernovae interacting with Si and S-rich circumstellar matter from double white dwarf mergers
Takashi J. Moriya, Chengyuan Wu, Dongdong Liu +2
We present that supernovae interacting with a dense Si and S-rich circumstellar matter like SN 2021yfj can originate from mergers of two white dwarfs. A C+O white dwarf accreting H…
Type Ia Supernova Explosions in Binary Systems: A Review
Zheng-Wei Liu, Friedrich K. Roepke, Zhanwen Han
SNe Ia play a key role in the fields of astrophysics and cosmology. It is widely accepted that SNe Ia arise from thermonuclear explosions of WDs in binaries. However, there is no c…
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…
Observational signatures of the surviving donor star in the double detonation model of Type Ia supernovae
Zheng-Wei Liu, Friedrich K. Roepke, Yaotian Zeng +1
The sub-Chandrasekhar mass double-detonation (DDet) scenario is a contemporary model for SNe Ia. The donor star in the DDet scenario is expected to survive the explosion and to be…
Still Brighter than Pre-Explosion, SN 2012Z Did Not Disappear: Comparing Hubble Space Telescope Observations a Decade Apart
Curtis McCully, Saurabh W. Jha, Richard A. Scalzo +10
Type Iax supernovae represent the largest class of peculiar white-dwarf supernovae. The type Iax SN~2012Z in NGC 1309 is the only white dwarf supernova with a detected progenitor s…
Long-term evolution of surviving companion stars of Type Iax supernovae
Zheng-Wei Liu, Yaotian Zeng
The nature of the progenitors and explosion mechanism of Type Iax supernovae (SNe Iax) remain a mystery. The single-degenerate (SD) systems that involve the incomplete pure deflagr…
A closer look at non-interacting He stars as a channel for producing the old population of Type Ia supernovae
Zheng-Wei Liu, Richard J. Stancliffe
The nature of the progenitors of type Ia supernovae (SNe Ia) remains a mystery. Binary systems consisting of a white dwarf (WD) and a main-sequence (MS) donor are potential progeni…
The interaction of Type Iax supernova ejecta with a helium companion star
Yaotian Zeng, Zheng-Wei Liu, Zhanwen Han
Type Iax supenovae (SNe Iax) are an important sub-luminous class of SNe Ia. However, their progenitors and explosion mechanism have not been understood yet. It has been suggested t…
White dwarf deflagrations for Type Iax supernovae: Polarisation signatures from the explosion and companion interaction
M. Bulla, Z. -W. Liu, F. K. Roepke +5
Growing evidence suggests that Type Iax supernovae might be the result of thermonuclear deflagrations of Chandrasekhar-mass white dwarfs in binary systems. We carry out Monte Carlo…
Circumstellar properties of Type Ia supernovae from the helium star donor channel
Takashi J. Moriya, Dongdong Liu, Bo Wang +1
We investigate predicted circumstellar properties of Type Ia supernova progenitor systems with non-degenerate helium star donors. It has been suggested that systems consisting of a…
The interaction of core-collapse supernova ejecta with a stellar companion
Zheng-Wei Liu, T. M. Tauris, F. K. Roepke +4
The progenitors of many core-collapse supernovae (CCSNe) are expected to be in binary systems. By performing a series of three-dimensional hydrodynamical simulations, we investigat…
Rates and delay times of Type Ia supernovae in the helium-enriched main-sequence donor scenario

Double neutron star (DNS) systems represent extreme physical objects and the endpoint of an exotic journey of stellar evolution and binary interactions. Large numbers of DNS system…
Can the Helium-Enriched Main-Sequence Donor Scenario Hide Enough Hydrogen to Explain Type Ia Supernovae?
