Interplanetary Lyman line profiles: variations with solar activity cycle
Eric Quémerais, Rosine Lallement, Jean-Loup Bertaux +4
Interplanetary Lyman alpha line profiles are derived from the SWAN H cell data measurements. The measurements cover a 6-year period from solar minimum (1996) to after the solar max…
Stellar Populations at the Center of IC 1613
Andrew A. Cole, Eline Tolstoy, John S. Gallagher +18
We have observed the center of the Local Group dwarf irregular galaxy IC 1613 with WFPC2 aboard the Hubble Space Telescope in the F439W, F555W, and F814W filters. We find a dominan…
WFPC2 Observations of Compact Star Cluster Nuclei in Low Luminosity Spiral Galaxies
Lynn D. Matthews, John S. Gallagher, III +16
We have used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to image the compact star cluster nuclei of the nearby, late-type, low-luminosity spiral galaxies N…
Detection of Surface Brightness Fluctuations in NGC 4373 Using the Hubble Space Telescope
M. A. Pahre, J. R. Mould, A. Dressler +1
Surface brightness fluctuations (SBF) have been detected for three elliptical galaxies-NGC 3379 in the Leo group, NGC 4406 in the Virgo cluster, and NGC 4373 in the Hydra-Centaurus…
Far-Ultraviolet and Visible Imaging of the Nucleus of M32
A. A. Cole, J. S. Gallagher, J. R. Mould +1
We have imaged the nucleus of M32 at 1600 Angstroms (FUV) and 5500 Angstroms (V) using the Wide-Field/Planetary Camera 2 (WFPC2) aboard HST. We detected the nucleus at 1600 Angstro…
Stellar Populations in Three Outer Fields of the LMC
Marla C. Geha, Jon A. Holtzman, Jeremy R. Mould +16
We present HST photometry for three fields in the outer disk of the LMC extending approximately four magnitudes below the faintest main sequence turnoff. We cannot detect any stron…
