Elemental Abundances from Off-center Carbon Burning in Accreting CO White Dwarfs: Implications for SN 2021yfj-like events
Chengyuan Wu, Dongdong Liu, Takashi J. Moriya +3
SN 2021yfj is a recently discovered interacting supernova that exhibits narrow emission lines of Si, S, and Ar, indicating the presence of circumstellar material (CSM) enriched wit…
Formation of black holes from He stars
Gang Long, Bo Wang, Philipp Podsiadlowski +5
Massive He stars are potential candidates of type Ib/c supernova (SN) progenitors. Understanding their final fates remains a key issue in astrophysics. In this work, we investigate…
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…
The diverse morphology of gravitational wave signals from merging neutron-star white-dwarf binaries
Shenghua Yu, Youjun Lu, C. Simon Jeffery +6
In sufficiently compact neutron star-white dwarf (NSWD) binary systems, orbital decay means the white dwarf eventually fills its shrinking Roche lobe, initiating a phase of mass tr…
The Impact of Reaction on the Evolution of He Stars
Gang Long, Yu Wang, Dongdong Liu +2
The reaction is one of the most important reactions in the evolution of massive stars, yet its rate is still highly uncertain. In this wo…
The Formation of Electron-capture Supernovae: A Review
Bo Wang, Dongdong Liu, Yunlang Guo +1
It is generally believed that the electron-capture reactions happen when the oxygen-neon (ONe) cores grow in masses close to the Chandrasekhar limit, leading to the formation of ne…
Eclipsing millisecond pulsars with He star companions
Yunlang Guo, Bo Wang, Xiangdong Li +2
Eclipsing millisecond pulsars (MSPs) are a type of pulsar binaries with close orbits (d). They are important objects for studying the accretion history of neutron st…
Supernovae at Distances < 40 Mpc: II. Supernova Rate in the Local Universe
Xiaoran Ma, Xiaofeng Wang, Jun Mo +21
Context.This is the second paper of a series aiming to determine the birth rates of supernovae in the local Universe. Aims. In this paper, we aim to estimate the SN rates in the lo…
Ultraluminous X-ray sources with He star companions
Luhan Li, Bo Wang, Dongdong Liu +3
Ultraluminous X-ray sources (ULXs) are non-nuclear point-like objects observed with extremely high X-ray luminosity that exceeds the Eddington limit of a black hol…
He-accreting oxygen-neon white dwarfs and accretion-induced collapse events
Zhengyang Zhang, Chengyuan Wu, Amar Aryan +3
It has been widely accepted that mass-accreting white dwarfs (WDs) are the progenitors of Type Ia supernovae or electron-capture supernovae. Previous work has shown that the accret…
Formation of millisecond pulsars with long orbital periods by accretion-induced collapse of white-dwarfs
Bo Wang, Dongdong Liu, Hailiang Chen
Accretion-induced collapse (AIC) of massive white-dwarfs (WDs) has been proposed as an important way for the formation of neutron star (NS) systems. An oxygen-neon (ONe) WD that ac…
The effect of aspherical stellar wind of giant stars on the symbiotic channel of type Ia supernovae
Chengyuan Wu, Dongdong Liu, Xiaofeng Wang +1
The progenitor systems accounting for explosions of type Ia supernovae (SNe Ia) is still under debate. Symbiotic channel is one of the possible progenitor scenarios, in which the W…
He-shell flashes on the surface of oxygen-neon white dwarfs
Yunlang Guo, Dongdong Liu, Chengyuan Wu +1
Accretion induced collapse (AIC) may be responsible for the formation of some interesting neutron star binaries, e.g., millisecond pulsars, intermediate-mass binary pulsars, etc. I…
The formation of single neutron-stars from double white-dwarf mergers via accretion-induced collapse
Dongdong Liu, Bo Wang
The merging of double white dwarfs (WDs) may produce the events of accretion-induced collapse (AIC) and form single neutron stars (NSs). Meanwhile, it is also notable that the rece…
The formation of neutron star systems through accretion-induced collapse in white-dwarf binaries
Bo Wang, Dongdong Liu
The accretion-induced collapse (AIC) scenario was proposed 40 years ago as an evolutionary end state of oxygen-neon white-dwarfs (ONe WDs), linking them to the formation of neutron…
Evolving neutron star+helium star systems to intermediate-mass binary pulsars
Tang Wenshi, Liu Dongdong, Wang Bo
Intermediate-mass binary pulsars (IMBPs) are composed of neutron stars (NSs) and CO/ONe white dwarfs (WDs). It is generally suggested that IMBPs evolve from intermediate-mass X-ray…
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 outcomes of carbon-oxygen white dwarfs accreting CO-rich material
Chengyuan Wu, Bo Wang, Dongdong Liu
The double-degenerate model, involving the merger of double carbon-oxygen white dwarfs (CO WDs), is one of the two classic models for the progenitors of type Ia supernovae (SNe Ia)…
Past and future of the central double-degenerate core of Henize 2-428
