HST-WFPC2 Observations of the Star Clusters in the Giant HII Regions of M33
Myung Gyoon Lee, Hong Soo Park, Sang Chul Kim +4
We present a photometric study of the stars in ionizing star clusters embedded in several giant HII regions of M33 (CC93, IC 142, NGC 595, MA2, NGC 604 and NGC 588). Our photometry…
Dwarf Spheroidal Galaxies in the M81 Group Imaged with WFPC2
I. D. Karachentsev, V. E. Karachentseva, A. E. Dolphin +7
We obtained HST/WFPC2 images of the dwarf spheroidal (dSph) galaxies K61, K63, K64, DDO78, BK6N, and kk77 in the M81 group. Our color-magnitude diagrams show red giant branches wit…
A Dwarf Galaxy Survey in the Local Volume
E. K. Grebel, P. Seitzer, A. E. Dolphin +6
We are carrying out a comprehensive multi-wavelength study of dwarf galaxies in the Local Volume (< 5 Mpc). After our all-sky survey more than doubled the dwarf census we are now m…
Large scale star formation in galaxies. I. The spirals NGC 7217, NGC 1058 and UGC 12732
P. Battinelli, R. Capuzzo-Dolcetta, P. W. Hodge +2
We present multiband photometric observations of three spiral galaxies selected in a sample suited for the study of young stellar groupings and their relationship with the parent g…
The dwarf spheroidal galaxy DDO 44: stellar populations and distance
I. D. Karachentsev, M. E. Sharina, E. K. Grebel +7
We present ground-based and HST WFPC2 imaging of the nearby low surface brightness dwarf spheroidal galaxy DDO 44. For the first time DDO 44 was resolved into stars. The resulting…
