Evolutionary tracks of massive stars with different rotation and metallicity in neutrino H-R diagram
Hao Wang, Chunhua Zhu, Helei Liu +2
Neutrino losses play a crucial role in the evolution of massive stars. We study the neutrino luminosity of stars ranging from 20 to 90 M_{\odot} from Zero Age Main Sequence (ZAMS)…
EOS-dependent millihertz quasi-periodic oscillation in low-mass X-ray binary
Helei Liu, Yong Gao, Zhaosheng Li +4
We studied the frequency and critical mass accretion rate of millihertz quasi-periodic oscillations (mHz QPOs) using a one-zone X-ray burst model. The surface gravity is specified…
An Alternative Formation Scenario for Uranium-rich Giants: Engulfing a Earth-like Planet
Dian Xie, Chunhua Zhu, Sufen Guo +2
The actinides, such as the uranium (U) element, are typically synthesized through the rapid neutron-capture process (r-process), which can occur in core-collapse supernovae or doub…
Scientific Objectives of the Hot Universe Baryon Surveyor (HUBS) Mission
Joel Bregman, Renyue Cen, Yang Chen +51
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spa…
The effects of rotation, metallicity and magnetic field on the islands of failed supernovae
Lei Li, Chunhua Zhu, Sufen Guo +2
Failed supernovae (FSN) are a possible channel for the formation of heavy stellar-mass black holes ( M). However, the effects of metallicity, rotation and…
The Impacts of Neutron-Star Structure and Base Heating on Type I X-Ray Bursts and Code Comparison
Guoqing Zhen, Guoliang Lv, Helei Liu +6
Type I X-ray bursts are rapidly brightening phenomena triggered by thermonuclear burning on accreting layer of a neutron star (NS). The light curves represent the physical properti…
Hydrogen-free Wolf-Rayet stars: Helium stars with envelope-inflation structure and rotation
Xizhen Lu, Chunhua Zhu, Helei Liu +3
Observations have shown that the effective temperature of hydrogen-free Wolf-Rayet (WR) stars is considerably lower than that of the standard model, which means that the radius of…
