We found 50 new globular cluster (GC) candidates around M\,31 with Gaia Early Data Release 3 (EDR3), with the help from Pan-STARRS1 DR1 magnitudes and Pan-Andromeda Archaeological…
SPar: estimating stellar parameters from multi-band photometries with empirical stellar libraries
Mingxu Sun, Bingqiu Chen, Helong Guo +3
Modern large-scale photometric surveys have provided us with multi-band photometries of billions of stars. Determining the stellar atmospheric parameters, such as the effective tem…
Evolved Massive Stars at Low-metallicity V. Mass-Loss Rate of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +17
We assemble the most complete and clean red supergiant (RSG) sample (2,121 targets) so far in the Small Magellanic Cloud (SMC) with 53 different bands of data to study the MLR of R…
Validations and Corrections of the SFD and Planck Reddening Maps Based on LAMOST and Gaia Data
Yang Sun, Haibo Yuan, Bingqiu Chen
Precise correction of dust reddening is fundamental to obtain the intrinsic parameters of celestial objects. The Schlegel et al. (SFD) and the Planck 2D extinction maps are widely…
