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…
Galactic open cluster Cepheids -- a census based on Gaia EDR3
Xiaoyue Zhou, Xiaodian Chen
In the Gaia era, the membership analysis and parameter determination of open clusters (OCs) are more accurate. We performed a census of OC's classical Cepheids based on Gaia Early…
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…
Eclipsing Binary Populations across the Northern Galactic Plane from the KISOGP survey
Fangzhou Ren, Richard de Grijs, Huawei Zhang +8
We present a catalog of eclipsing binaries in the northern Galactic Plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP). We visually identified 70…
Evolved Massive Stars at Low-metallicity IV. Using 1.6 m "H-bump" to identify red supergiant stars: a case study of NGC 6822
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +9
We present a case study of using a novel method to identify red supergiant (RSG) candidates in NGC 6822, based on their 1.6 m "H-bump". We collected 32 bands of photometric data…
