Gravitinos and a Low Ultimate Temperature for the Early Universe
, 1994 We obtain new stronger bounds by orders of magnitude, on the ultimate temperature of the universe by exploiting the copious production of gravitinos at finite temperature.Comment: 14 PAGES (3 figs.

CCD Photometry of the Globular Cluster M53. I. Color-Magnitude Data and Blue Straggler Stars
The Astronomical Journal, 1998 The first large-format CCD color-magnitude diagram (CMD) in the B and V passbands is presented for the Galactic globular cluster M53 (NGC 5024). The observations consist of 40 pairs of B and V CCD frames with FWHM < 12 in a pattern covering a 12' × 13' region of M53. These frames were used to produce color-magnitude data for more than 20,000 stars from

The Dwarf Spheroidal Companions to M31: Variable Stars in Andromeda VI
, 2002 We have surveyed Andromeda VI, a dwarf spheroidal galaxy companion to M31, for variable stars using F450W and F555W observations obtained with the Hubble Space Telescope. A total of 118 variables were found, with 111 being RR Lyrae, 6 anomalous Cepheids,

Characteristics and classification of A-type supergiants in the Small Magellanic Cloud
, 2003 We address the relationship between spectral type and physical properties for A-type supergiants in the SMC. We first construct a self-consistent classification scheme for A supergiants, employing the calcium K to H epsilon line ratio as a temperature ...
