GALEX and Pan-STARRS1 Discovery of SN IIP 2010aq: The First Few Days After Shock Breakout in a Red Supergiant Star
S. Gezari, A. Rest, M. E. Huber +34
We present the early UV and optical light curve of Type IIP supernova (SN) 2010aq at z=0.0862, and compare it to analytical models for thermal emission following SN shock breakout…
Worlds Beyond: A Strategy for the Detection and Characterization of Exoplanets
J. I. Lunine, D. Fischer, H. Hammel +13
This is a scientific strategy for the detection and characterization of extrasolar planets; that is, planets orbiting other stars. As such, it maps out over a 15-year horizon the t…
High resolution spectroscopy of ultracool M dwarfs
I. Neill Reid, J. Davy Kirkpatrick, J. Liebert +3
(abridged) We present high-resolution echelle spectroscopy of a photometricaly-selected sample if thirty-nine dwarfs with spectral types between M6.5 and L0.5. Two stars, 2MASSI 02…
The Spectra of T Dwarfs I: Near-Infrared Data and Spectral Classification
Adam J. Burgasser, J. Davy Kirkpatrick, Michael E. Brown +9
We present near-infrared spectra for a sample of T dwarfs, including eleven new discoveries made using the Two Micron All Sky Survey. These objects are distinguished from warmer (L…
Three Wide-Separation L dwarf Companions from the Two Micron All Sky Survey: Gl 337C, Gl 618.1B, and HD 89744B
J. C. Wilson, J. Davy Kirkpatrick, J. E. Gizis +3
We present two confirmed wide separation L-dwarf common proper motion companions to nearby stars and one candidate identified from the Two Micron All Sky Survey. Spectral types fro…
Substellar Companions to Main Sequence Stars: No Brown Dwarf Desert at Wide Separations
John E. Gizis, J. Davy Kirkpatrick, Adam Burgasser +4
We use three field L and T dwarfs which were discovered to be wide companions to known stars by the Two Micron All-Sky Survey (2MASS) to derive a preliminary brown dwarf companion…
