Surveying the outbursts of AM CVns with TESS

Outbursting AM Canum Venaticorum (AM CVn) systems are accreting white dwarfs (WD) in binaries with ultra-short periods and with Helium dominated accretion disks. Their exotic characteristics make their study relevant for binary stellar evolution, gravitational wave astronomy, and accretion physics under extreme conditions. Observations of their outbursts, especially continuous and high cadence from space-based telescopes, are fundamental to place constraints on the accretion models currently used to explain their photometric behavior. In this work we present the current status of an AM CVn survey that exploits the 20-second cadence capacity of the Transiting Exoplanet Survey Satellite (TESS) to study AM CVn outbursts. Characteristics such as normal outbursts, superoutbursts, precursors and/or rebrightenings are identified in some of the targets. We discuss the implications of such features in the current accretion model of these binaries.
