Sky in Google Earth: The Next Frontier in Astronomical Data Discovery and Visualization
Ryan Scranton, Andrew Connolly, Simon Krughoff +7
Astronomy began as a visual science, first through careful observations of the sky using either an eyepiece or the naked eye, then on to the preservation of those images with photo…
HST Observations of Galactic Globular Cluster Cores. II. NGC 6273 and the Problem of Horizontal-Branch Gaps
G. Piotto, M. Zoccali, I. R. King +3
We present observations of the center of the Galactic globular cluster NGC 6273, obtained with the HST/WFPC2 camera as part of the snapshot program GO-7470. A B, V color-magnitude…
Mass Segregation and Equipartition of Energy in Two Globular Clusters with Central Density Cusps
Craig Sosin
We begin by presenting the analysis of a set of deep B- and V-band images of the central density cusp of the globular cluster M30 (NGC 7099), taken with the Faint Object Camera abo…
Discovery of Extended Blue Horizontal Branches in Two Metal-Rich Globular Clusters
R. Michael Rich, Craig Sosin, S. George Djorgovski +7
We have used WFPC2 to construct B, V color-magnitude diagrams of four metal-rich globular clusters, NGC 104 (47 Tuc), NGC 5927, NGC 6388, and NGC 6441. All four clusters have well…
Peculiar Multimodality on the Horizontal Branch of the Globular Cluster NGC 2808
Craig Sosin, Ben Dorman, S. George Djorgovski +6
We present distributions of colors of stars along the horizontal branch of the globular cluster NGC 2808, from Hubble Space Telescope WFPC2 imaging in B, V, and an ultraviolet filt…
HST Observations of High-Density Globular Clusters
G. Piotto, C. Sosin, I. R. King +6
In this paper we present preliminary results from our HST project aimed at exploring the connection between the stellar dynamics and stellar evolution in the cores of high-density…
