Universal scaling between magnetar field and initial spin period for short gamma ray bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +5
The -- correlation serves as a critical probe of magnetar engine physics. Although this scaling relation has been firmly established for long gamma-ray bursts (lGRBs), sy…
Tidally Trapped Two-pole Pulsations Discovered in a Close Binary with a Massive Cephei Star
Ping Li, Wen-Ping Liao, Sheng-Bang Qian +4
Tidally tilted pulsators (TTPs), whose pulsation axis aligns with the binary's semi-major axis, represent a newly established class of oscillators in binary systems. While all prev…
Asteroseismology and Dynamics Reveal Interior Structure and Coeval Evolution in the Triply Post-Main-Sequence system DG Leo
Ping Li, Wen-Ping Liao, Sheng-Bang Qian +4
Scuti stars in binary or multiple systems serve as crucial probes for studying stellar pulsation and evolution. However, many such systems are not ideal for asteroseismology d…
New Evidence for Extragalactic Einstein Probe Transients associated with Long Gamma-ray Bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +1
The origin of extragalactic fast X-ray transients (EFXTs) remains a fundamental open question in high-energy astrophysics. The Einstein Probe (EP) mission provides a transformative…
The Cosmic Star Formation History: Insights from Kilonova-Associated Gamma-Ray Bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +2
The origin of the Universe and its material content remains one of the most fundamental questions in science. Gamma-ray bursts (GRBs), with their extreme luminosities and high-reds…
Orbital and Pulsation Analysis of 42 Heartbeat Stars Discovered in TESS Data
Min-Yu Li, Sheng-Bang Qian, Ai-Ying Zhou +7
Heartbeat stars (HBSs) are ideal laboratories for studying the formation and evolution of binary stars in eccentric orbits and their mutual tidal interactions. We present 42 new HB…
