A Search for Additional Bodies in the GJ 1132 Planetary System from 21 Ground-based Transits and a 100 Hour Spitzer Campaign
Jason A Dittmann, Jonathan M Irwin, David Charbonneau +2
We present the results of a search for additional bodies in the GJ 1132 system through two methods: photometric transits and transit timing variations of the known planet. We colle…
Discovery and Precise Characterization by the MEarth Project of LP 661-13, an Eclipsing Binary Consisting of Two Fully Convective Low-mass Stars
Jason A Dittmann, Jonathan M Irwin, David Charbonneau +7
We report the detection of stellar eclipses in the LP 661-13 system. We present the discovery and characterization of this system, including high resolution spectroscopic radial ve…
The Impact of Stellar Rotation on the Detectability of Habitable Planets Around M Dwarfs
Elisabeth R. Newton, Jonathan Irwin, David Charbonneau +2
Stellar activity and rotation frustrate the detection of exoplanets through the radial velocity technique. This effect is particularly of concern for M dwarfs, which can remain mag…
