Photometric Analysis and Classification of Young stars (PACY)

Alessandro Salvatore Tramuto

We discuss the study of young stellar objects (YSOs) in the bluest bands (e.g., u and g filters) available in Rubin LSST, using Color-Color and Color-Magnitude diagrams to investigate the presence of the accretion process (explored in the Rubin Science Platform portal and notebook aspects). We also show light curves of YSOs to investigate their peculiar variability and the physical causes behind it. YSOs show variability associated to a diverse range of physical processes, e.g., from accretion of material from the surrounding medium, to absorption due to warped disks, to rotational modulation due to spots. We also discuss how the peculiar time scales associated to the variability in YSOs, that span from short-term variability of hours-days to long-term variability of months-years, can be caught taking advantage of high cadence visits (useful for short-term variability), and how we may take advantage of the whole duration of Rubin LSST main survey to probe the entirety of the long-term processes.
