Formation, diffusion and accreting pollution of DB white dwarfs
Chunhua Zhu, Helei Liu, Zhaojun Wang +1
Over 1500 DBZ or DZ white dwarfs (WDs) have been observed so far, and polluted atmospheres with metal elements have been found among these WDs. The surface heavy element abundances…
Possible Formation Scenarios of ZTF J153932.16+502738.8-A Gravitational Source Close to the Peak of LISA's Sensitivity
Guoliang Lü, Chunhua Zhu, Zhaojun Wang +4
ZTF J153932.16+502738.8 (ZTFJ1539) is an eclipsing double-white-dwarf system with an orbital period of 6.91 minutes, and is a significant source of LISA detecting gravitational wav…
The Formation of Bimodal Dust Species in Nova Ejecta
Adili Duolikun, Chunhua Zhu, Zhaojun Wang +4
The formation of bimodal dust species (namely the silicate and amorphous carbon dust grains coexistent) in a nova eruption is an open problem. According to the nova model simulated…
The formation of subdwarf A-type stars
Jinlong Yu, Zhenwei Li, Chunhua Zhu +6
Subdwarf A-type stars (sdAs) are objects that have hydrogen-rich spectra with surface gravity similar to that of hot subdwarf stars but effective temperature below the zero-age hor…
The Formation of Bimodal Dust Species in Nova Ejecta I: Chemical Conditions
Chunhua Zhu, Helei Liu, Guoliang Lü +2
The formation of bimodal dust species (that is, both of silicate and amorphous carbon dust grains are observed in a nova eruption) in nova ejecta is still debated. Using the Module…
A Study of Wolf-Rayet stars Formed via Chemically Homogeneous Evolution
Zhe Cui, Zhaojun Wang, Chunhua Zhu +3
Using the stellar evolution code---Modules for Experiments in Stellar Astrophysics (MESA), we investigate the evolution of massive stars with different rotational velocities and me…
Effects of Irradiation on the Evolution of Ultra-compact X-ray Binaries
Guoliang Lü, Chunhua Zhu, Zhaojun Wang +1
Using the Modules for Experiments in Stellar Astrophysics code, we investigate the influences of irradiation on ultra-compact X-ray binary (UCXB) evolution. Although the persistent…
Effects of the core-collapse supernova ejecta impact on a rapidly rotating massive companion star
Chunhua Zhu, Guoliang Lu, Zhaojun Wang
We investigate the effects of the core-collapse supernova ejecta on a rapidly rotating and massive companion star. We show that the stripped mass raises by twice when compare with…
The Contribution of Chemical Abundances in Nova Ejecta to the Interstellar Medium
Fanger Li, Chunhua Zhu, Guoliang Lu +1
According to the nova model from \citet{Yaron2005} and \citet{Jose1998} and using Monte Carlo simulation method, we investigate the contribution of chemical abundances in nova ejec…
The diamagnetic phase transition in Magnetars
Zhaojun Wang, Guoliang Lu, Chunhua Zhu +1
Neutron stars are ideal astrophysical laboratories for testing theories of the de Haas-van Alphen (dHvA) effect and diamagnetic phase transition which is associated with magnetic d…
A New Dust Budget In The Large Magellanic Cloud
Chunhua Zhu, Guoliang Lv, Zhaojun Wang
The origin of dust in a galaxy is poorly understood. Recently, the surveys of the Large Magellanic Cloud (LMC) provide astrophysical laboratories for the dust studies. By a method…
Origin of Dust around V1309 Sco
Chunhua Zhu, Guoliang Lu, Zhaojun Wang
The origin of dust grains in the interstellar medium is still open problem. \cite{Nicholls2013} found the presence of a significant amount of dust around V1309 Sco which maybe orig…
Low-mass X-ray Binaries with Strange Quark Stars
Chunhua Zhu, Guoliang Lv, Zhaojun Wang +1
Strange quark stars (SSs) may originate from accreting neutron stars (NSs) in low-mass X-ray binaries (LMXBs). Assuming that conversion of NS matter to SSs occurs when the core den…
Donors of Persistent Neutron-star Low-mass X-ray Binaries
Chunhua Zhu, Guoiliang Lv, Zhaojun Wang +1
Properties of X-ray luminosities in low-mass X-ray binaries (LMXBs) mainly depend on donors. We have carried out a detailed study of donors in persistent neutron-star LMXBs (PLMXBs…
The Shoenberg Effect in Relativistic Degenerate Electron Gas and Observational Evidences in Magnetars
Zhaojun Wang, Guoliang Lv, Chunhua Zhu +1
The electron gas inside a neutron star is highly degenerate and relativistic. Due to the electron-electron magnetic interaction, the differential susceptibility can equal or exceed…
Gamma-ray sources like V407 Cygni in Symbiotic Stars
Guoliang Lu, Chunhua Zhu, Zhaojun Wang +2
Using a simple accelerating model and an assumption that -rays originate from collisions for a model, we investigate -ray sources like V407 Cygni in symbiotic sta…
Soft and Supersoft X-ray Sources in Symbiotic Stars
Chunhua Zhu, Guoliang Lu, Zhaojun Wang +1
Assuming that soft X-ray sources in symbiotic stars result from strong thermonuclear runaways, and supersoft X-ray sources from weak thermonuclear runaways or steady hydrogen burni…
An Alternative Symbiotic Channel to Type Ia Supernovae
Guoliang Lv, Chunhua Zhu, Zhaojun Wang +1
By assuming an aspherical stellar wind with an equatorial disk from a red giant, we investigate the production of Type Ia supernovae (SNe Ia) via symbiotic channel. We estimate tha…
