Effects of Mutual Transits by Extrasolar Planet
... emissions come from the faint objects. In a single transit, on the other hand, thermal emissions from a transiting object at lower temperature make a difference in light curves during the secondary eclipse, when the object moves behind a parent star as observed for instance for HD209458b (Deming et ...
