Observations of fast-moving features in the debris disk of AU Mic on a three-year timescale: Confirmation and new discoveries
(2018)Astronomy & AstrophysicsContext. The nearby and young M star AU Mic is surrounded by a debris disk in which we previously identified a series of large-scale arch-like structures that have never been seen before in any other debris disk and that move outward at high velocities. Aims. We initiated a monitoring program with the following objectives: (1) track the location of the structures and better constrain their projected speeds, (2) search for new features ...Journal Article
