METHOD
FOR SPOT DETECTION ON A SOLAR-LIKE STAR

As the planet eclipses its
parent star, a dark starspot may be occulted, causing a detectable variation in
the light curve. This work describes how features on the surface of a solarlike
star can be studied by using planetary transits. Images of the Sun were used in
order to simulate such transits, with the planet being modelled as a dark disk
at various positions along its orbit. From modelling of these transits it might
be possible to infer the physical properties of the spots, such as size,
intensity, position, and emperature. Recent transits observations for HD 209458
were used as tests to the model.
