Abstract
We investigated the connection between disks and stellar rotation. Disk-locking theory predicts that accreting stars are preferentially slow rotators compared to their peers. If true, classical T Tauri stars (CTTS), which are accreting based on strong Ha emission, should have observably lower v sin i values compared to weak-lined T Tauri stars (WTTS), which are not accreting. We present our findings from high-resolution optical spectra taken with the Magellan Inamori Kyocera Echelle (MIKE) spectrograph on the Magellan Clay 6.5-m telescope located at the Las Campanas Observatory of 63 T Tauri stars in the Cha I SFR.
