FROM THE May 2011 ISSUE

How does one differentiate between an exoplanet orbiting in front of a distant sun and a large starspot traveling across that starт??s disk?

Melvyn Goldberg, Toronto, Canada

The light curve of an exoplanet transiting its star (top) is different from that of a starspot traversing a starт??s disk, so astronomers can tell the two signals apart. Astronomy: Roen Kelly

Thus we can distinguish a transit by the short duration of the dip. ... so the dip of a transit is slightly т??U-shaped.т?? The shape of the starspot dip has gentle sides and looks more т??V-shaped.т??
