Abstract:
We report the discovery of a planet with a high planet-to-star mass
ratio in the microlensing event MOA-2009-BLG-387, which exhibited
pronounced deviations over a 12-day interval, one of the longest for
any planetary event. The host is an M dwarf, with a mass in the range
0.07M☉<Mhost<0.49M∑ at 90% confidence. The planet-star mass
ratio q=0.0132±0.003 has been measured extremely well, so at the
best-estimated host mass, the planet mass is mp=2.6 Jupiter masses
for the median host mass, M=0.19M☉.
Description:
The RoboNet collaboration also followed the event with their three 2m
robotic telescopes : the Faulkes Telescopes The microlensing event
MOA-2009-BLG-387 was alerted North (FTN) and South (FTS) in Hawaii and
Australia by the MOA collaboration (Microlensing Observations in
(Siding Springs Observatory) respectively, and the Liverpool
Astrophysics) on 24 July 2009 at 15:08 UT,
HJD'=HJD-24500000=5037.13, a few days before the first caustic
entry. Many observatories obtained data of the event. The celestial
coordinates of the event are RA=17:53:50.79 and DE=-33:59:25
(J2000.0) corresponding to Galactic coordinates:
l=+356.56, b=-4.097.
