Gaia18dcu: a three-magnitude brightness increase from a 50,000K stellar object
Abstract
We call attention to the unusual host object of a blue transient, Gaia18dcu, in the Kepler field. The object is noteworthy in having a very hot quiescent SED which we find dominates not only the UV but also the visible bandpasses, a quiescent Lbol of at least 11x Lsun over several years, and a strong H-alpha excess in at least one quiescent epoch.
