The cradle of the cradles of planets
Planets form in tiny disks around newly-born stars. Hundreds of
high-resolution images of these disks have been taken over the last
decade showing a variety of diverse morphologies that are somehow
connected to the diversity observed in planetary systems. Now, the
sample of disks observed is mature enough to enable demographic studies
on several disk properties and their connection with environmental,
stellar, and other disk properties. The techniques, the instruments, and
the main results of our study are presented in this talk, with a
particular view of three star-forming regions where tens of planets are
being formed.
