Near-Infrared Photometric Study of the Old Open Cluster Trumpler 5
Sang Chul Kim, Jaemann Kyeong, Eon-Chang Sung
We present JHK near-infrared photometric study for the old open cluster (OC) Trumpler 5 (Tr 5), based on the 2MASS data. From the color-magnitude diagrams of Tr 5, we have located…
RACE-OC Project: Rotation and variability in the open cluster M11 (NGC6705)
S. Messina, P. Parihar, J. -R. Koo +3
Rotation and magnetic activity are intimately linked in main-sequence stars of G or later spectral types. The presence and level of magnetic activity depend on stellar rotation, an…

We report the detection of the C IV 1548, 1551 emission line in the region of the RCW 114 nebula using the FIMS/SPEAR data. The observed C IV line intensity indicates that RCW 114…
The TAOS Project Stellar Variability I. Detection of Low-Amplitude delta Scuti Stars
D. -W. Kim, P. Protopapas, C. Alcock +22
We analyzed data accumulated during 2005 and 2006 by the Taiwan-American Occultation Survey (TAOS) in order to detect short-period variable stars (periods of <~ 1 hour) such as del…
Origin and evolution of galactic spin from looking at galaxy pairs
Bernardo Cervantes-Sodi, X. Hernandez, Changbom Park
To study if the angular momentum gain for each member of a galaxy pair was the result of tidal torques imprinted by the same tidal field, we search for correlations between the spi…
Limb-darkening measurements for a cool red giant in microlensing event OGLE 2004-BLG-482
M. Zub, A. Cassan, D. Heyrovsky +47
Aims: We present a detailed analysis of OGLE 2004-BLG-482, a relatively high-magnification single-lens microlensing event which exhibits clear extended-source effects. These events…
Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events
C. Han, K. -H. Hwang, D. Kim +87
To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of len…
The nature of the Sloan Digital Sky Survey galaxies in various classes based on morphology, colour and spectral features - III. Environments
Joon Hyeop Lee, Myung Gyoon Lee, Changbom Park +1
We present a study on the environments of the SDSS galaxies divided into fine classes based on their morphology, colour and spectral features. The SDSS galaxies are classified into…
Long-term Photometric Behavior of the Eclipsing Binary GW Cephei
Jae Woo Lee, Jae-Hyuck Youn, Wonyong Han +5
New CCD photometry during 4 successive years from 2005 is presented for the eclipsing binary GW Cep, together with reasonable explanations for the light and period variations. All…
Magnetic Field Structure of the HH 1-2 Region: Near-Infrared Polarimetry of Point-Like Sources
Jungmi Kwon, Minho Choi, Soojong Pak +4
The HH 1-2 region in the L1641 molecular cloud was observed in the near-IR J, H, and Ks bands, and imaging polarimetry was performed. Seventy six point-like sources were detected i…
Detection of a Planetary Companion around the giant star \gam1leo
Inwoo Han, B. C. Lee, K. M. Kim +3
Aims: Our primary goal is to search for planets around intermediate mass stars. We are also interested in studying the nature of radial velocity (RV) variations of K giant stars. M…
Spitzer and HHT observations of starless cores: masses and environments
Amelia M. Stutz, George H. Rieke, John H. Bieging +6
We present Spitzer observations of a sample of 12 starless cores selected to have prominent 24 micron shadows. The Spitzer images show 8 and 24 micron shadows and in some cases 70…
