Description
Using the Hectochelle multifiber spectrograph, we have obtained high-resolution (R~34000) spectra in the H{alpha} region for a large number of stars in the 4Myr old cluster Tr 37, containing 146 previously known members and 26 newly identified ones. We present the H{alpha} line profiles of all members, compare them to our IR observations of dusty disks (Two Micron All Sky Survey JHK + IRAC + MIPS 24um), use the radial velocities as a membership criterion, and calculate the rotational velocities.
