A prolonged plateau-to-tail transition in the Type II supernova SN2025abyc
Luhan Li, Bo Wang, Jujia Zhang +6
We present optical photometric and spectroscopic observations of the Type II supernova SN2025abyc. During the optically thick phase between approximately 10 and 70 d after explosio…
The double white dwarf merger model for the progenitors of SN 2021yfj-like events
Dongdong Liu, Chengyuan Wu, Takashi J. Moriya +4
Context. Recently, a new class of supernovae with prominent narrow emission features of Si, S and Ar has been reported, i.e. SN 2021yfj-like events (SNe Ien). Their progenitor orig…
Stellar Parameters and Orbital Period Estimates for Composite-Spectrum sdB+MS Binaries from LAMOST
Jiangdan Li, Jianping Xiong, Jiao Li +5
Hot subdwarf (sdB) stars in binary systems with main-sequence (MS) companions provide valuable insights into mass transfer and envelope ejection processes in binary evolution. Thei…
SN2024abfl: A Low-Luminosity Type IIP Supernova at the Low-Mass End of Core Collapse
Luhan Li, Jujia Zhang, Zeyi Zhao +8
We present optical photometric and spectroscopic observations of the low-luminosity (LL) Type IIP supernova SN\,2024abfl. The distance to its host galaxy is highly uncertain, with…
A seven-Earth-radius helium-burning star inside a 20.5-min detached binary
Jie Lin, Chengyuan Wu, Heran Xiong +28
Binary evolution theory predicts that the second common envelope (CE) ejection can produce low-mass (0.32-0.36 Msun) subdwarf B (sdB) stars inside ultrashort-orbital-period binary…
