Coronal Mass Ejections As a Mechanism for Producing IR Variability in Debris Disks
arXiv:1302.2546 · doi:10.1088/2041-8205/765/2/L44
Abstract
Motivated by recent observations of short-timescale variations in the infrared emission of circumstellar disks, we propose that coronal mass ejections can remove dust grains on timescales as short as a few days. Continuous monitoring of stellar activity, coupled to infrared observations, can place meaningful constraints on the proposed mechanism.
