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…
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…
Physical parameter study of eight W Ursae Majoris-type contact binaries in NGC 188
Xiaodian Chen, Licai Deng, Richard de Grijs +10
We used the newly commissioned 50 cm Binocular Network (50BiN) telescope at Qinghai Station of Purple Mountain Observatory (Chinese Academy of Sciences) to observe the old open clu…
White-Light Flares on Close Binaries Observed with Kepler
Qing Gao, Yu Xin, Ji-Feng Liu +2
Based on Kepler data, we present the results of a search for white-light flares on 1049 close binaries. We identify 234 flare binaries, on which 6818 flares are detected. We compar…
Optical Observing Conditions at Delingha Station
J. F. Tian, L. C. Deng, X. B. Zhang +10
SONG is a global ground based network of 1 meter telescopes for stellar time-domain science, an international collaboration involving many countries across the world. In order to e…
Formation of new stellar populations from gas accreted by massive young star clusters
Chengyuan Li, Richard de Grijs, Licai Deng +4
Stars in star clusters are thought to form in a single burst from a common progenitor cloud of molecular gas. However, massive, old globular clusters -- with ages greater than 10 b…
