Dusty Exoplanetary Debris Disks in the Single-Temperature Blackbody Plane

Solar and Stellar Astrophysics 2018-09-20 v1

Abstract

We present a bulk sample analysis of the metal polluted white dwarfs which also host infrared bright dusty debris disks, known to be direct signatures of an active exoplanetary accretion source. We explore the relative positions of these systems in a single-temperature blackbody plane, defined as the temperature and radius of a single-temperature blackbody as fitted to the infrared excess. We find that the handful of dust systems which also host gaseous debris in emission congregate along the high temperature boundary of the dust disk region in the single-temperature blackbody plane. We discuss interpretations of this boundary and propose the single-temperature blackbody plane selection technique for use in future targeted searches of gaseous emission.
