Exoplanet Transit Search For GJ 436
Abstract:
Dr. Greg Laughlin has requested help in observing GJ 436 to look for transits of previously detected and undetected extrasolar planets. A Neptune mass planet was recently discovered transiting this M2V class star with a photometric depth of 0.6% and a period of 2.64 days.
Justification:
The radial velocity data set for the star indicates that the transiting planet has a significant eccentricity. The presence of an eccentric orbit strongly indicates the presence of additional planets in the system. These can potentially be detected through transit or precise timing of the transits of the known transiting planet.
