Abstract:
The nature of the few known solar mass stars containing debris disks
and planets simultaneously remains an open question. Many authors have
shown that this property appears to be independent on planetary masses
and also on stellar age, but never studied possible correlations with
stellar kinematics and metallicity. In this paper we show that the
majority of known stars containing both, debris disks and planets,
belong to the metal enriched Galactic thin-disk. The few exceptions
are stars that seem to be born in the star formation peak occurred in
the thick-disk formation times (HD10700, HD20794 and HD40307), i.e.,
between 11 and 8Gyr. The dusty disk's mass of these three old stars
measured at 70um is very small, in fact it is less than that of the
Kuiper belt of our Solar system by several orders of magnitude. These
values are not surprising as are within the values expected for the
stellar disk evolution of these primitive stars. In parallel, we have
found other six thick-disk primitive stars but those containing only
debris disks and stars containing only planets. These results enables
us to establish a correlation between stellar metallicity and the dust
disk mass modulated by the different epochs of the Galactic disks
formation.
