Parent stars of extrasolar planets - XII. Additional evidence for trends with v sin i, condensation temperature and chromospheric activity
Abstract
Several recent studies have reported differences in v sin i, abundance-condensation temperature trends and chromospheric activity between samples of stars with and without Doppler-detected planets. These findings have been disputed, and the status of these results remains uncertain. We evaluate these claims using additional published data and find support for all three.
