Abstract:
We investigate two topics regarding solar mass FGK-type stars, the
lithium rotation connection (LRC) and the existence of the "lithium
desert". We determine the minimum critical rotation velocity (vsini)
related with the LRC separating slow from rapid stellar rotators, as
being 5km/s. This value also split different stellar properties.
For the first time we explore the behaviour of the LRC for some
stellar associations with ages between 45Myr and 120Myr. This allows
us to study the LRC age dependence at the beginning of the general
spin down stage for low mass stars, which starts at ∼30-40Myr.
We find that each stellar group presents a characteristic minimum
lithium (Li) depletion connected to a specific large rotation velocity
and that this minimum changes with age. For instance, this minimum
changes from ∼50km/s to less than 20km/s in 200Myr. Regarding the
lithium desert, it was described as a limited region in the
A(Li)-Teff map containing no stars. Using Teff from Gaia DR2 we
detect 30 stars inside and/or near the same box defined originally as
the Li desert. Due to their intrinsic Teff errors some of these stars
may be inside or outside the box, implying a large probability that
the box contains several stars. Considering this last fact the
"lithium desert" appears to be more a statistical distribution
fluctuation than a real problem.
Description:
File table1 lists the whole collection of the stars related to this
work with their stellar properties and references. The stellar ages
and masses were derived using L. Girardi on-line code PARAM 1.3
(http://stev.oapd.inaf.it/cgi-bin/param). This table 1 also
proportionate Lithium abundances and chromospheric activity and U, V,
W galactocentric velocities.
