Blue straggler stars beyond the Milky Way. IV. Radial distributions and dynamical implications
Chengyuan Li, Weijia Sun, Jongsuk Hong +3
Blue straggler stars have been proposeed as powerful indicators to measure the dynamical state of Galactic globular clusters. Here we examine for the first time if this framework o…
The double blue straggler sequence in NGC 2173: a field contamination artefact?
Chengyuan Li, Licai Deng, Richard de Grijs +2
Li et al. (2018) (hereafter L18) detected two apparently distinct populations of blue straggler stars (BSSs) in the young globular cluster NGC 2173, a similar feature as observed i…
Blue straggler populations beyond the Milky Way
Richard de Grijs, Weijia Sun, Chengyuan Li +1
Although the formation of blue straggler stars (BSSs) is routinely attributed to stellar interactions in binary systems, the relative importance of the direct collision and slow(er…
Blue straggler stars beyond the Milky Way. III. Detection of evolved blue straggler candidates in Large Magellanic Cloud clusters
Chengyuan Li, Licai Deng, Kenji Bekki +3
We analyze {\sl Hubble Space Telescope} observations of nine Large Magellanic Cloud star clusters with ages of 1--2 Gyr to search for evolved counterparts of blue straggler stars.…
Blue straggler stars beyond the Milky Way. II. A binary origin for blue straggler stars in Magellanic Cloud clusters
Weijia Sun, Chengyuan Li, Richard de Grijs +1
We have analyzed populations of blue straggler stars (BSSs) in 24 Magellanic Cloud star clusters using multi-passband Hubble Space Telescope images. We compiled a homogeneous BSS d…
New insights into the formation of the blue main sequence in NGC 1850
Yujiao Yang, Chengyuan Li, Licai Deng +2
Recent discoveries of bimodal main sequences (MSs) associated with young clusters (with ages Gyr) in the Magellanic Clouds have drawn a lot of attention. One of the pr…
Blue straggler stars beyond the Milky Way: a non-segregated population in the Large Magellanic Cloud cluster NGC 2213
Chengyuan Li, Jongsuk Hong
Using the high-resolution observations obtained by the Hubble Space Telescope, we analyzed the blue straggler stars (BSSs) in the Large Magellanic Cloud cluster NGC 2213. We found…
Multiple stellar populations in Magellanic Cloud clusters. VI. A survey of multiple sequences and Be stars in young clusters
A. P. Milone, A. F. Marino, M. Di Criscienzo +16
The split main sequences (MSs) and extended MS turnoffs (eMSTOs) detected in a few young clusters have demonstrated that these stellar systems host multiple populations differing i…
An unexpected detection of bifurcated blue straggler sequences in the young globular cluster NGC 2173
Chengyuan Li, Licai Deng, Richard de Grijs +2
Bifurcated patterns of blue straggler stars in their color--magnitude diagrams have atracted significant attention. This type of special (but rare) pattern of two distinct blue str…
