Brightness "dips" caused by two transiting exoplanets

Brightness "dips" of the stars OGLE-TR-113 (upper) and OGLE-TR-132 (lower), as observed during the OGLE survey. It is now known that they are caused by transiting extra-solar planets (exoplanets) of the new "very hot Jupiter" class. The abscissa represents the orbital phase (one revolution = 1) and the ordinate the relative brightness. As can be seen the brightness variations are of the order of 3 % (upper) and 1% (lower), respectively.
