UBVI CCD Photometry of the Old Open Cluster NGC 1193
Jaemann Kyeong, Sang Chul Kim, David Hiriart +1
We present UBVI photometry of the old open cluster NGC 1193. Color-magnitude diagrams (CMDs) of this cluster show a well defined main sequence and a sparse red giant branch. For th…
Near-Infrared Photometry of the Star Clusters in the Dwarf Irregular Galaxy IC 5152
Jaemann Kyeong, Eon-Chang Sung, Sang Chul Kim +2
We present JHK-band near-infrared photometry of star clusters in the dwarf irregular galaxy IC 5152. After excluding possible foreground stars, a number of candidate star clusters…
Infrared study of the eta Chamaeleontis cluster and the longevity of circumstellar discs
A-Ran Lyo, Warrick A. Lawson, Eric M. Mamajek +3
We have analyzed JHKL observations of the stellar population of the ~9 Myr-old eta Chamaeleontis cluster. Using infrared (IR) colour-colour and colour-excess diagrams, we find the…
The Intrinsic Shapes of Low-Surface-Brightness Dwarf Irregular Galaxies and Comparison to Other Types of Dwarf Galaxies
Eon-Chang Sung, Cheongho Han, Barbara +8
In this paper, we measure the ellipticities of 30 LSB dI galaxies and compare the ellipticity distribution with that of 80 dEs (Ryden & Terndrup 1994; Ryden et al. 1998) and 62 BCD…
A Comparison of the Intrinsic Shapes of Two Different Types of Dwarf Galaxies: Blues Compact Dwarfs and Dwarf Ellipticals
Eon-Chang Sung, Cheongho Han, Barbara +3
We measure the apparent shapes for a sample of 62 blue compact dwarf galaxies (BCDs), and compare them with the apparent shapes for a sample of 80 dwarf elliptical galaxies (dEs).…
