A Survey for Supernovae in Massive High-Redshift Clusters
Keren Sharon, A. Gal-Yam, D. Maoz +12
We describe our ongoing program designed to measure the SN-Ia rate in a sample of massive z=0.5-0.9 galaxy clusters. The SN-Ia rate is a poorly known observable, especially at high…
Dust Coagulation and Settling in Layered Protoplanetary Disks
Fred J. Ciesla
Previous models of dust growth in protoplanetary disks considered either uniformly laminar or turbulent disks. This Letter explores how dust growth occurs in a layered protoplaneta…
When do early-type galaxies form?
Roberto G. Abraham, Patrick J. McCarthy, Erin Mentuch +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys to measure the mass density function of morphologically selected early-type galaxies in the Gemini Deep Deep S…
Eclipsing Binaries: Tools for Calibrating the Extragalactic Distance Scale
A. Z. Bonanos
In the last decade, over 7000 eclipsing binaries have been discovered in the Local Group through various variability surveys. Measuring fundamental parameters of these eclipsing bi…
Planet Formation with Migration
J. E. Chambers
In the core-accretion model, gas-giant planets form solid cores which then accrete gaseous envelopes. Tidal interactions with disk gas cause a core to undergo inward type-I migrati…
A Long-Period Jupiter-Mass Planet Orbiting the Nearby M Dwarf GJ849
R. Paul Butler, John A. Johnson, Geoffrey W. Marcy +3
We report precise Doppler measurements of GJ849 (M3.5V) that reveal the presence of a planet with a minimum mass of 0.82 Mjup in a 5.16 year orbit. At a = 2.35 AU, GJ849b is the fi…
