Optical-infrared flares and radio afterglows from the tidal disruption of Jovian planets by their host star
Authors:

Abstract:
When a Jovian planet gets sufficiently close to its host star to be tidally disrupted, its debris stream deposits energy on the star's surface, producing an expanding bubble of hot plasma. We study the radiation from the bubble and show that it includes optical-infrared prompt emission and a subsequent radio afterglow. The prompt emission from M31 and Large Magellanic Cloud is detectable by optical-near infrared transient surveys with a large field of view at an event rate of a few events per year. The subsequent radio afterglows are detectable for 103−4~years.
