The Shape of M Dwarf Flares in Kepler Light Curves
James R. A. Davenport
Ultra-precise light curves from Kepler provide the best opportunity to determine rates and statistical properties of stellar flares. From 11 months of data on the active M4 dwarf,…
Characterizing the Rigidly Rotating Magnetosphere Stars HD 345439 and HD 23478
J. P. Wisniewski, S. D. Chojnowski, J. R. A. Davenport +8
The SDSS III APOGEE survey recently identified two new Ori E type candidates, HD 345439 and HD 23478, which are a rare subset of rapidly rotating massive stars whose large (kGa…
Characterizing the Habitable Zones of Exoplanetary Systems with a Large Ultraviolet/Visible/Near-IR Space Observatory
Kevin France, Evgenya Shkolnik, Jeffrey Linsky +32
Understanding the surface and atmospheric conditions of Earth-size, rocky planets in the habitable zones (HZs) of low-mass stars is currently one of the greatest astronomical endea…
Detecting Differential Rotation and Starspot Evolution on the M dwarf GJ 1243 with Kepler
James R. A. Davenport, Leslie Hebb, Suzanne L. Hawley
We present an analysis of the starspots on the active M4 dwarf GJ 1243, using four years of time series photometry from Kepler. A rapid day rotation period…
The Time Domain Spectroscopic Survey: Variable Object Selection and Anticipated Results
Eric Morganson, Paul J. Green, Scott F. Anderson +37
We present the selection algorithm and anticipated results for the Time Domain Spectroscopic Survey (TDSS). TDSS is an SDSS-IV eBOSS subproject that will provide initial identifica…
Testing the recovery of stellar rotation signals from Kepler light curves using a blind hare-and-hounds exercise
S. Aigrain, J. Llama, T. Ceillier +10
We present the results of a blind exercise to test the recoverability of stellar rotation and differential rotation in Kepler light curves. The simulated light curves lasted 1000 d…
