White dwarfs identified in LAMOST Data Release 5
Jincheng Guo, Jingkun Zhao, Huawei Zhang +5
In this paper, we report white dwarfs identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope, including spectral types of DA, DB, DC, DZ, a…
Further evidence of shocks in the first-overtone RR Lyrae pulsators: first detection of shock-triggered magnesium emissions
Xiao-Wei Duan, Weijia Sun, Xiaodian Chen +2
The behavior of the shock wave in the atmosphere of the non-fundamental mode RR Lyrae pulsator remains a mystery. In this work, we firstly report a blueshifted Mg triplet emission…
Most "young" -rich stars have high masses but are actually old
Meng Zhang, Mao-Sheng Xiang, Hua-Wei Zhang +8
Recent observations have revealed a population of -element abundances enhanced giant stars with unexpected high masses (1 ) from asteroseismic analysis and spe…
Discovery of multiple p-mode pulsation frequencies in the roAp star, HD 86181
Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth +5
We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be = 0.48753 $\pm…
Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3
Yang Huang, Timothy C. Beers, Christian Wolf +8
Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galax…
Gaia EDR3 Parallax Zero-point Offset based on W Ursae Majoris-type Eclipsing Binaries
Fangzhou Ren, Xiaodian Chen, Huawei Zhang +3
We independently determine the zero-point offset of the Gaia early Data Release-3 (EDR3) parallaxes based on W Ursae Majoris (EW)-type eclipsing binary systems. EWs…
