detection of a Neptune - class
planet in an inner orbit

(V = 5.5), confirming previous
planet detection with an independent RV technique.
Young stars (only 100 million years old) are prime targets for planetary
detection through imaging because the
planets around them are still flush
with the heat of their formation and are therefore brighter.
The presence of ozone helps to explain the
detection of hydroxyl (an unstable molecule of oxygen
with a single atom of hydrogen) high in
planet's atmosphere in 2008 (ESA news releases on ozone, sulfur dioxide, and hydroxyl; Lisa Grossman, New Scientist, October 6, 2011; and Montmessin et al, 2011).

Further scrutiny of the TW Hya disk
with GPI and SPHERE in their differential coronagraphic imaging modes may yield direct
