Abstract

ABSTRACT: We report the discovery of 19 new R Coronae Borealis (RCB) star and DY Per candidates with light curves from the All-Sky Automated Survey for Supernovae. We examined both an existing set of 1602 near/mid-infrared (IR) selected candidates and an additional 2615 candidates selected to have near/mid-IR spectral energy distributions consistent with those of known RCB stars. We visually inspected the light curves for the characteristic variability of these systems.
