The GJ1214 Super-Earth System: Stellar Variability, New Transits, and a Search for Additional Planets
Zachory K. Berta, David Charbonneau, Jacob Bean +5
The super-Earth GJ1214b transits a nearby M dwarf that exhibits 1% intrinsic variability in the near-infrared. Here, we analyze new observations to refine the physical properties o…
On the angular momentum evolution of fully-convective stars: rotation periods for field M-dwarfs from the MEarth transit survey
Jonathan Irwin, Zachory K. Berta, Christopher J. Burke +4
We present rotation period measurements for 41 field M-dwarfs, all of which have masses inferred (from their parallaxes and 2MASS K-band magnitudes) to be between the hydrogen burn…
Precise Estimates of the Physical Parameters for the Exoplanet System HD-17156 Enabled by HST FGS Transit and Asteroseismic Observations
Philip Nutzman, Ronald L. Gilliland, Peter R. McCullough +6
We present observations of three distinct transits of HD 17156b obtained with the Fine Guidance Sensors (FGS) on board the Hubble Space Telescope} (HST). We analyzed both the trans…
Asteroseismology of the Transiting Exoplanet Host HD 17156 with HST FGS
Ronald L. Gilliland, Peter R. McCullough, Edmund P. Nelan +5
Observations conducted with the Fine Guidance Sensor on Hubble Space Telescope (HST) providing high cadence and precision time-series photometry were obtained over 10 consecutive d…
NLTT 41135: a field M-dwarf + brown dwarf eclipsing binary in a triple system, discovered by the MEarth observatory
Jonathan Irwin, Lars Buchhave, Zachory K. Berta +13
We report the discovery of an eclipsing companion to NLTT 41135, a nearby M5 dwarf that was already known to have a wider, slightly more massive common proper motion companion, NLT…
