Carbon in J0815+4729: Casting a shadow of doubt on the interpretation of CH absorption in the most primitive stars

Junbo Zhang, Carlos Allende Prieto, Yeisson Osorio +7

Aims. We revisit the carbon abundance in the primitive iron-poor star J0815+4729 ([Fe/H] = -5.49). J0815+4729 is so carbon-enhanced and oxygen-rich that, in addition to CH and C2 m…

A Systematic NLTE Study of Very Metal-Poor Stars with Metallicity Down to dex. II. Lithium Abundance and New Insight to the Lithium Plateau

Hong-Liang Yan, Jinxiao Qin, Shuai Liu +12

Metal-poor stars are crucially important for understanding the early Galaxy, first stars, and the Universe. In this series of papers, we present a homogeneous non-local thermodynam…

Spectral Dataset of Stripped-Envelope Supernovae from the Tsinghua Supernova Group

Danfeng Xiang, Xiaofeng Wang, Jujia Zhang +40

The extent of envelope stripping in the progenitor stars is directly reflected in the diversity of spectral features observed in stripped-envelope supernovae (SESNe). Through exten…

A potential mass-gap black hole in a wide binary with a circular orbit

Wang Song, Zhao Xinlin, Feng Fabo +28

Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised t…

A spectral data release for 104 Type II Supernovae from the Tsinghua Supernova Group

Han Lin, Xiaofeng Wang, Jujia Zhang +33

We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…

KIC 12268220: A Scuti Pulsating Star and an Active Protohelium White Dwarf in an Eclipsing Binary System

Kaiming Cui, Zhao Guo, Qing Gao +4

We present a photometric, spectroscopic, asteroseismic, and evolutionary analysis of the Algol-type eclipsing binary KIC 12268220. We find the O'Connell effect and anticorrelated e…
