Planetary systems are built by planets and planetesimals formed in
circumstellar disks surrounding young pre-main sequence stars. Once in
the main-sequence collisions of planetesimals produce small dust
particles giving rise to the so-called debris disks. The mutual
interaction among planets, planetesimals and debris disks, and with
their host stars determines the fate of planetary systems.
Currently thousands of main-sequence stars are known to host planets and
debris disks. The Solar System with its peculiarities is just one of
such planetary systems. However, only few tens of stars are known to
host simultaneously both planets and debris disks. Therefore, the
study of those systems is particularly valuable to widen our knowledge
of planetary systems and their evolution.
This page just collects some of the properties of the known, to our knowledge,
solar-type stars hosting both planets and debris disk.
