Statistical Searches for Microlensing Events in Large, Non-Uniformly Sampled Time-Domain Surveys: A Test Using Palomar Transient Factory Data
Adrian M. Price-Whelan, Marcel A. Agüeros, Amanda P. Fournier +7
Many photometric time-domain surveys are driven by specific goals, such as searches for supernovae or transiting exoplanets, which set the cadence with which fields are re-imaged.…
Near-infrared Metallicities, Radial Velocities and Spectral Types for 447 Nearby M Dwarfs
Elisabeth R. Newton, David Charbonneau, Jonathan Irwin +4
We present metallicities, radial velocities and near-infrared spectral types for 447 M dwarfs determined from moderate resolution (R~2000) near-infrared (NIR) spectra obtained with…
A Gyrochronology and Microvariability Survey of the Milky Way's Older Stars Using Kepler's Two-Wheels Program
Saurav Dhital, Terry D. Oswalt, Philip S. Muirhead +7
Even with the diminished precision possible with only two reaction wheels, the Kepler spacecraft can obtain mmag level, time-resolved photometry of tens of thousands of sources. Th…
Targeting Young Stars with Kepler: Planet Formation, Migration Mechanisms and the Early History of Planetary Systems
James P. Lloyd, Jonathan I. Lunine, Eric Mamajek +7
This white paper discusses a repurposed mission for the Kepler spacecraft that focusses on solving outstanding problems in planet formation and evolution by targeting the study of…
New Uses for the Kepler Telescope: A Survey of the Ecliptic Plane For Transiting Planets and Star Formation
Charles Beichman, David Ciardi, Rachel Akeson +8
With the loss of two reaction wheels, the period of Kepler's ultra-high precision photometric performance is at an end. Yet Kepler retains unique capabilities impossible to replica…
Characterization of the gaseous companion κ Andromedae b: New Keck and LBTI high-contrast observations
M. Bonnefoy, T. Currie, G. -D. Marleau +64
We previously reported the direct detection of a low mass companion at a projected separation of 55+-2 AU around the B9 type star κ Andromedae. The properties of the system (mass r…
