Characteristic Scales in Stellar Clustering: A Transition Near the Disk Scale Height
Mary Crone Odekon
The autocorrelation function provides an objective test for the existence of special scales in the hierarchical clustering of young stars. We apply this measure to single-star phot…
The Correlation Dimension of Young Stars in Dwarf Galaxies
Mary Crone Odekon
We present the correlation dimension of resolved young stars in four actively star-forming dwarf galaxies that are sufficiently resolved and transparent to be modeled as projection…
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…
