Optical Monitoring of Young Stellar Objects
Abstract
Observing Young Stellar Objects (YSOs) for variability in different wavelengths enables us to understand the evolution and structure of the protoplanetary disks around stars. The stars observed in this project are known YSOs that show variability in the Infrared. Targets were selected from the Spitzer Space Telescope Young Stellar Object Variability (YSOVAR) Program, which monitored star forming regions in the mid-infrared. The goal of our project is to investigate any correlation between the variability in the infrared versus the optical. Infrared variability of YSOs are associated with the heating of the protoplanetary disk while stellar signatures are observed in optical wavelengths. We used the University of Wyoming's Red Buttes Observatory to monitor these stars for signs of accretion using the Johnson Cousins filter set, over the Summer of 2017. We perform relative photometry and inspect for an image-to-image variation by observing these targets for a period of four months every two to three nights. The study helps us better understand stellar activity and establish a disk-star connection.
