Revisiting the Radial Velocities of Nearby Open Clusters using Gaia DR3
Tong Tang, Yu Zhang, Jing Zhong +4
Open clusters (OCs) are essential laboratories for probing stellar dynamics and tracing the structure and evolution of the Milky Way. Accurate measurements of their average radial…
Interstellar Object 3I/ATLAS Observed from Mars by China's Tianwen-1 Spacecraft
Xin Ren, Wei Yan, Ruining Zhao +20
China's Tianwen-1 Mars orbiter successfully imaged the third interstellar object, 3I/ATLAS, during its close encounter with Mars using the onboard HiRIC CMOS camera. This is China'…
Variation of the 2175 Ã extinction feature in Andromeda galaxy
Bing Yan, Shu Wang, Jian Gao +2
Extinction curves contain key information on interstellar dust composition and size distribution, with the 2175 Ã bump being the most prominent feature. We analyze 20 sightlines to…
The Samples and Binary Fractions of Red Supergiant in M31 and M33 by the HST Observations
Min Dai, Shu Wang, Biwei Jiang +1
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda Galaxy (M31) and Triangulu…
The Multi-wavelength Extinction Law and its Variation in the Coalsack Molecular Cloud Based on the Gaia, APASS, SMSS, 2MASS, GLIMPSE, and WISE Surveys
Juan Deng, Shu Wang, Biwei Jiang +1
Accurate interpretation of observations relies on the interstellar dust extinction law, which also serves as a powerful diagnostic for probing dust properties. In this study, we in…
