| Exoplanetary Scratchpad |
A Very Hot Jupiter with the shortest known period (19h) for a transiting planet at the time of its discovery late in 2009 and currently has the shortest known period for a Hot Jupiter. It's mass is slightly greater than Jupiter, but its diameter is 30% greater, making it as large as some small stars. The planet appeared brighter than expected, perhaps due to a lack of Titanian and Vanadian Oxides in the upper stratosphere (perhaps at a lower level so that it doesn't act as a dark layer). Molecules were not detected, but models suggest two possibilities, either a Carbon rich planet (plenty of CO and CH4) or a Oxygen rich planet (containing plenty of CO, CO2, and H2O). The planet is only at 1.2 times the Roche limit and likely moved inwards due to interactions with a third body. One of 5 exoplanets whose water abundance was measured by Hubble in 2013 and found to be less abundant than expected, probably due to a layer of haze or dust blocking detection.
