The Oldest Stars of the Extremely Metal-Poor Local Group Dwarf Irregular Galaxy Leo A
Regina E. Schulte-Ladbeck, Ulrich Hopp, Igor O. Drozdovsky +2
We present deep Hubble Space Telescope single-star photometry of Leo A in B, V, and I. Our new field of view is offset from the centrally located field observed by Tolstoy et al. (…
The Dwarf Irregular/Wolf-Rayet Galaxy NGC4214: I. A New Distance, Stellar Content, and Global Parameters
Igor O. Drozdovsky, Regina E. Schulte-Ladbeck, Ulrich Hopp +2
We present the results of a detailed optical and near-IR study of the nearby star-forming dwarf galaxy NGC4214. We discuss the stellar content, drawing particular attention to the…
The Star Formation History of the Blue Compact Dwarf Galaxy UGCA 290
Mary M. Crone, Regina E. Schulte-Ladbeck, Laura Greggio +1
We present the star formation history of UGCA 290, a galaxy with properties intermediate between Blue Compact Dwarfs and Dwarf Irregulars. This galaxy is particularly interesting b…
The Stellar Content of NGC 6789, A Blue Compact Dwarf Galaxy in the Local Void
Igor O. Drozdovsky, Regina E. Schulte-Ladbeck, Ulrich Hopp +2
We find that NGC6789 is the most nearby example of a Blue Compact Dwarf galaxy known to date. With the help of WFPC2 aboard the Hubble Space Telescope, we resolve NGC6789 into over…
A Near-Infrared Stellar Census of Blue Compact Dwarf Galaxies: The Wolf-Rayet Galaxy I Zw 36
Regina E. Schulte-Ladbeck, Ulrich Hopp, Laura Greggio +2
We report the results of near-IR imaging in J and H, of I Zw 36 (Z/14) with the Hubble Space Telescope. Whereas imaging with the pre-COSTAR Faint Object Camera (…
A Compact Population of Red Giants in the Blue Compact Dwarf Galaxy UGCA 290
Mary M. Crone, Regina E. Schulte-Ladbeck, Ulrich Hopp +1
We present HST/WFPC2 single-star photometry for the blue dwarf galaxy UGCA 290, whose morphology is intermediate between classic iE Blue Compact Dwarfs and blue dwarfs which exhibi…
