A deep optical survey of young stars in the Carina Nebula. I. -- UBVRI photometric data and fundamental parameters
Hyeonoh Hur, Beomdu Lim, Moo-Young Chun
We present the deep homogeneous photometric data of 135,071 stars down to mag and I ~ 22 mag toward the Carina Nebula. These stars are cross-matched with those fr…
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…
The initial mass function of young open clusters in the Galaxy: A preliminary result
Beomdu Lim, Hwankyung Sung, Hyeonoh Hur +1
The initial mass function (IMF) is an essential tool with which to study star formation processes. We have initiated the photometric survey of young open clusters in the Galaxy, fr…
Sejong open cluster survey (SOS) - V. The active star forming region Sh 2-255 -- 257
Beomdu Lim, Hwankyung Sung, Hyeonoh Hur +6
There is much observational evidence that active star formation is taking place in the HII regions Sh 2-255 -- 257. We present a photometric study of this star forming region (SFR)…
Sejong Open Cluster Survey (SOS) - IV. The Young Open Clusters NGC 1624 and NGC 1931
Beomdu Lim, Hwankyung Sung, Michael S. Bessell +3
Young open clusters located in the outer Galaxy provide us with an opportunity to study star formation activity in a different environment from the solar neighborhood. We present a…
Reddening, Distance, and Stellar Content of the Young Open Cluster Westerlund 2
Hyeonoh Hur, Byeong-Gon Park, Hwankyung Sung +4
We present deep photometric data of the young open cluster Westerlund 2. An abnormal reddening law of was found for the highly reddened early-type m…
[Fe II] 1.64 um Features of Jets and Outflows from Young Stellar Objects in the Carina Nebula
Jong-Ho Shinn, Tae-Soo Pyo, Jae-Joon Lee +11
We present [Fe II] 1.64 μm imaging observations for jets and outflows from young stellar objects (YSOs) over the northern part (~ 24'x45') of the Carina Nebula, a massive star form…
Sejong Open Cluster Survey (SOS). 0. Target Selection and Data Analysis
Hwankyung Sung, Beomdu Lim, Michael S. Bessell +4
Star clusters are superb astrophysical laboratories containing cospatial and coeval samples of stars with similar chemical composition. We have initiated the Sejong Open cluster Su…
The Starburst Cluster Westerlund 1: The Initial Mass Function and Mass Segregation
Beomdu Lim, Moo-Young Chun, Hwankyung Sung +5
Westerlund 1 is the most important starburst cluster in the Galaxy due to its massive star content. We have performed BVIc and JKs photometry to investigate the initial mass functi…
Distance and the Initial Mass Function of Young Open Clusters In The Eta Carina Nebula: Tr 14 and Tr 16
Hyeonoh Hur, Hwankyung Sung, Michael S. Bessell
We present new UBVI_C CCD photometry of the young open clusters Trumpler 14 (Tr 14) and Trumpler 16 (Tr 16) in the eta Carina nebula. We also identify the optical counterpart of Ch…
