Warm Dust in Circumstellar Disks around Young Binary and Single Stars
Abstract
We present a study of young T Tauri stars in the Lupus, Corona Australis, and Ophiuchus star forming regions that is intended to indentify and characterize circumstellar disks. Twenty-one pre-main-sequence binary systems were observed, as well as thirty-three young X-ray sources. Photometry was taken in the K and L bands and K-L excesses were used to determine whether targets had circumstellar disks. For the X-ray sample, spectral lines were used to estimate vsin(i) and to look for a correlation between the presence of a disk and slow stellar rotation. The goals of this project were to determine the frequency of circumstellar disks around individual stars in binary systems, to investigate variations of NIR colors in these disks, and to search for disks around young X-ray sources in Ophiuchus.
