In this paper, a short-duration (~7 days) low-amplitude deviation in the light curve due to a single-lens profile was observed in both the MOA (Microlensing Observations in Astrophysics) and OGLE (Optical Gravitational Lensing Experiment) survey observations.Abstract:
We present observations of the unusual microlensing event OGLE 2003-BLG-235/MOA 2003-BLG-53. In this event, a short-duration (~7 days) low-amplitude deviation in the light curve due to a single-lens profile was observed in both the MOA (Microlensing Observations in Astrophysics) and OGLE (Optical Gravitational Lensing Experiment) survey observations. We find that the observed features of the light curve can only be reproduced using a binary microlensing model with an extreme (planetary) mass ratio of 0.0039 for the lensing system. If the lens system comprises a main-sequence primary, we infer that the secondary is a planet of about 1.5 Jupiter masses with an orbital radius of ~3 AU.read more

The use of transit timing to detect terrestrial-mass extrasolar planets.
Matthew J. Holman,Norman Murray +1 more
TL;DR: This work shows that timing measurements between successive transits will allow for the detection of additional planets in the system (not necessarily transiting) by their gravitational interaction with the transiting planet.

TL;DR: In this paper, the authors used a fraction of the guaranteed time on the ESO/HARPS spectrograph to estimate the radial velocities of 102 southern nearby M dwarfs, and then applied systematic searches for long-term trends, periodic signals, and Keplerian orbits.

TL;DR: The detection of a cool, sub-Neptune-mass planets may be more common than gas giant planets, as predicted by the core accretion theory, and is suggested to name OGLE-2005-BLG-390Lb, indicating a planetary mass companion to the lens star of the microlensing event.

The Core Accretion Model Predicts Few Jovian-Mass Planets Orbiting Red Dwarfs
TL;DR: In this article, the authors present theoretical calculations that show that the formation of Jupiter-mass planets orbiting M dwarfs is seriously inhibited at all radial locations (in sharp contrast to solar-type stars).
