STIS Coronagraphic Observations of Beta Pictoris
Sara R. Heap, Don J. Lindler, Thierry M. Lanz +4
We present new coronagraphic images of Beta Pictoris obtained with the Space Telescope Imaging Spectrograph (STIS) in September 1997. The high-resolution images (0.1") clearly dete…
On The Age Estimation of LBDS 53W091
Sukyoung YI, T. M. Brown, S. Heap +4
The recent spectral analysis of LBDS 53W091 by Spinrad and his collaborators has suggested that this red galaxy at z=1.55 is at least 3.5 Gyr old. This imposes an important constra…
Hot stellar population synthesis from the UV spectrum: the globular cluster M79 (NGC 1904)
Jorick S. Vink, Sara R. Heap, Allen V. Sweigart +2
We have analyzed the far UV-spectrum of the globular cluster M79. We show that the nearly Gaussian mass distribution of zero-age horizontal-branch stars, as derived by Dixon et al.…
Emission-Line Galaxies from the NICMOS/HST GRISM Parallel Survey
P. J. McCarthy, L. Yan, W. Freudling +10
We present the first results of a survey of random fields with the slitless G141 () grism on NICMOS. Approximately 64 square arcminutes have been observed at i…
