| Abstract: |
About 16 % of the main-sequence solar-like stars are surrounded by dusty
debris disks (DD). These disks are the
detritus of small bodies collisions and their presence is a very strong signpost
of planet formation. One of the most interesting characteristics of stars
hosting a giant planet is a direct relationship between metallicity and
probability of planet formation, which was found to increase with stellar
metallicity Gonzalez (1997). Instead, the
small planets would form around host stars (HS) with a wide range of metallicities
(Buchhave et al. 2012). On the
other hand the presence of debris disks is uncorrelated with metallicity (Chavero et
al. 2006, Greaves et al. 2006,
Maldonado et al. 2012). |
