The Sejong Open Cluster Survey (SOS). VII. A Photometric Study of the Young Open Cluster IC 1590
Seulgi Kim, Beomdu Lim, Michael S. Bessell +2
Young open clusters are ideal laboratories to understand star formation process. We present deep UBV I and Halpha photometry for the young open cluster IC 1590 in the center of the…
The Sejong Open cluster Survey (SOS) VI. A small star-forming region in the high Galactic latitude molecular cloud MBM 110
Hwankyung Sung, Michael S. Bessell, Inseok Song
We present optical photometric, spectroscopic data for the stars in the high Galactic latitude molecular cloud MBM 110. For the complete membership selection of MBM 110, we also an…
Extended main sequence turn-off originated from a broad range of stellar rotational velocities
Beomdu Lim, Gregor Rauw, Yael Naze +3
Star clusters have long been considered to comprise a simple stellar population, but this paradigm is being challenged, since apart from multiple populations in Galactic globular c…
Kinematic evidence for feedback-driven star formation in NGC 1893
Beomdu Lim, Hwankyung Sung, Michael S. Bessell +8
OB associations are the prevailing star forming sites in the Galaxy. Up to now, the process of how OB associations were formed remained a mystery. A possible process is self-regula…
An Optical and Infrared Photometric Study of the Young Open Cluster IC 1805 in the Giant H II Region W4
Hwankyung Sung, Michael S. Bessell, Moo-Young Chun +7
We present deep wide-field optical CCD photometry and mid-infrared Spitzer/IRAC and MIPS 24micron data for about 100,000 stars in the young open cluster IC 1805. The members of IC…
A constraint on the formation timescale of the young open cluster NGC 2264: Lithium abundance of pre-main sequence stars
Beomdu Lim, Hwankyung Sung, Jinyoung S. Kim +3
The timescale of cluster formation is an essential parameter in order to understand the formation process of star clusters. Pre-main sequence (PMS) stars in nearby young open clust…
