Parent stars of extrasolar planets - X. Lithium abundances and vsini revisited.


Abstract (from CDS):

We determine Li abundances and v sini values from new spectra of 53 stars with Doppler-detected planets not included in our previous papers in this series. We also examine two sets of stars without detected planets, which together serve as our comparison sample. Using the method of comparison of Li abundances and v sini values between two sets of stars we introduced in Gonzalez, we confirm that these two quantities are smaller among stars with planets (SWPs) compared to stars without detected planets near the solar temperature. The transition from low to high Li abundance among SWPs occurs near 5850K, a revision of about 50K from our previous determination. The transition from low to high v sini occurs near 6000K, but this temperature is not as well constrained.
