Photometric Search for Accretion Disks in Young Clusters: NGC 2414
Abstract
In order to search for the presence of an accretion disk around young stars, we have obtained optical (UBVRI) photometry and retrieved infrared (JHK) photometry from the public Two Micron All-Sky Survey (2MASS) database for the young cluster NGC 2414. With this information we have obtained color-color and color-magnitude diagrams searching for stars showing an infrared excess. Based on the (H - K) vs (J - H) diagram, we have identified 20 stars showing an infrared excess which are good candidates to possess an accretion disk.
