Digging Into the Surface of the Icy Dwarf Planet Eris
M. R. Abernathy, S. C. Tegler, W. M. Grundy +4
We describe optical spectroscopic observations of the icy dwarf planet Eris with the 6.5 meter MMT telescope and the Red Channel Spectrograph. We report a correlation, that is at t…
Evidence of N2-Ice On the Surface of the Icy Dwarf Planet 136472 (2005 FY9)
S. C. Tegler, W. M. Grundy, F. Vilas +3
We present high signal precision optical reflectance spectra of 2005 FY9 taken with the Red Channel Spectrograph and the 6.5-m MMT telescope on 2006 March 4 UT (5000 - 9500 A; 6.33…
Deep Photometry of GRB 041006 Afterglow: Hypernova Bump at Redshift z=0.716
K. Z. Stanek, P. M. Garnavich, P. A. Nutzman +17
We present deep optical photometry of the afterglow of gamma-ray burst (GRB) 041006 and its associated hypernova obtained over 65 days after detection (55 R-band epochs on 10 diffe…
Detection of Two Binary Trans-Neptunian Objects, 1997 CQ29 and 2000 CF105, with the Hubble Space Telescope
Keith S. Noll, Denise C. Stephens, Will M. Grundy +6
Images of the trans-Neptunian objects 1997 CQ29 and 2000 CF105 obtained with the Hubble Space Telescope's WFPC2 camera show them to be binary. The two components of 1997 CQ29 were…
Discovery of a Nuclear X-Ray Source in NGC 7331: Evidence for a Massive Black Hole
Christopher J. Stockdale, W. Romanishin, John J. Cowan
Using ROSAT, we have made the first deep X-ray observations of NGC 7331, discovering a nuclear X-ray source coincident with the previously determined radio and optical nuclear cent…
Statistical Connections Between the Properties of Type Ia Supernovae and the B--V Colors of Their Parent Galaxies, and the Value of H
David Branch, W. Romanishin, E. Baron
Statistical connections between the properties of Type Ia supernovae (SNe Ia) and the B--V colors of their parent galaxies are established. Compared to SNe Ia in blue galaxies [B-V…
