Gravity-mode main-sequence pulsators in the open clusters NGC 3532 and NGC 2516: Instability strip, near-core rotation, and internal structure
Gang Li, Chenyu He, Joey S. G. Mombarg +2
Context. Studying pulsating stars in clusters opens a new window onto stellar physics. Gravity-mode (g-mode) pulsators in open clusters allow us to measure their near-core rotation…
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…
Fast-rotating A- and F-type stars with Hα emissions in NGC 3532, candidate UV-dim stars?
Chenyu He, Chengyuan Li, Gang Li
Extended main-sequence stars that are dim in the ultraviolet passbands of Hubble Space Telescope (UV-dim stars) are found in several young and intermediate-age Magellanic Cloud sta…
On the roles of stellar rotation and binarity in NGC 2423's main-sequence turnoff region
Yutian Bu, Chenyu He, Li Wang +2
Research has shown that many young and intermediate-age clusters (younger than 2 Gyr) have extended main sequences and main-sequence turnoffs (eMSTOs), which cannot be adequa…
The role of tidal interactions in the formation of slowly rotating early-type stars in young star clusters
Chenyu He, Chengyuan Li, Weijia Sun +9
The split main sequences found in the colour-magnitude diagrams of star clusters younger than ~600 Myr are suggested to be caused by the dichotomy of stellar rotation rates of uppe…
On the origin of the split main sequences of the young massive cluster NGC 1856
Li Wang, Chengyuan Li, Long Wang +2
The detection of split main sequences (MSs) associated with young clusters (600 Myr) has caught lots of attention. A prevailing scenario is that a bimodality of stellar r…
The role of binarity and stellar rotation in the split main sequence of NGC 2422
Chenyu He, Weijia Sun, Chengyuan Li +8
In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (~ 600 Myr-2 Gyr-old) star clusters, some younger clusters even exhibit split main seq…
