Transit Detection of Planet b (2002)
The OGLE-III survey (Optical Gravitational Lensing Experiment) announced the detection of 54 short period multi-transiting objects in the Galactic bulge, including OGLE-TR-10 b and OGLE-TR-58 b.
Dopplar Follow Up on Planet b (2004)
Radial followup to determine planet's mass and other characteristics
Planet b Confirmed (Apr 2005)
Planets existance was confirmed with dopplar spectrometry
Planet b Losing Atmosphere (May 2005)
Theories show that Planet b is in a state of "classical hydrodynamical blow-off" and loses its atmosphere at a higher rate than most transiting exoplanets.
Planet b Not Inflated (Jun 2005)
Additional transits yield a smaller radius than previously announced, at 1.06 MJ
Planet b Really Is Inflated (Jan 2006)
Further analysis reveal that Planet b is infact an inflated Hot Jupiter with a radius of 1.22 RJ.
Chemical Abundance of Parent Star Measured (2005-2006)
Surface Gravity Found to Be Less Than Earth (2007)
