Searching for White Dwarf Candidates Formed Through Binary evolution in Star Clusters
Huahui Yan, Li Wang, David R. Miller +11
White dwarfs (WDs), the evolutionary endpoints of most stars, can form through both single-star and binary channels. While single-star evolutionary models enable reliable WD age es…
Multiple stellar populations at less evolved stages: detection of chemical variations among main-sequence dwarfs in NGC 1978
Chengyuan Li, Baitian Tang, Antonino P. Milone +4
Multiple stellar populations (MPs) with different chemical compositions are not exclusive features of old GCs (older than 10 Gyr). Indeed, recent studies reveal that younger cluste…
Physical Parameters of Late-type Contact Binaries in the Northern Catalina Sky Survey
Weijia Sun, Xiaodian Chen, Licai Deng +1
We present the physical parameters of 2335 late-type contact binary (CB) systems extracted from the Catalina Sky Survey (CSS). Our sample was selected from the CSS Data Release 1 b…
Tidal-locking-induced stellar rotation dichotomy in the open cluster NGC 2287?
Weijia Sun, Chengyuan Li, Licai Deng +1
Stars spend most of their lifetimes on the `main sequence' (MS) in the Hertzsprung--Russell diagram. The obvious double MSs seen in the equivalent color--magnitude diagrams charact…
Wide-field Infrared Survey Explorer (WISE) Catalog of Periodic Variable Stars
Xiaodian Chen, Shu Wang, Licai Deng +2
We have compiled the first all-sky mid-infrared variable-star catalog based on Wide-field Infrared Survey Explorer (WISE) five-year survey data. Requiring more than 100 detections…
The Near-infrared Optimal Distances Method Applied to Galactic Classical Cepheids Tightly Constrains Mid-infrared Period--Luminosity Relations
Shu Wang, Xiaodian Chen, Richard de Grijs +1
Classical Cepheids are well-known and widely used distance indicators. As distance and extinction are usually degenerate, it is important to develop suitable methods to robustly an…
