The multi-wavelength vertical structure of the archetypal Pictoris debris disk
Yinuo Han, Mark C. Wyatt, Marija R. Jankovic +4
Thermal imaging of debris disks is resolving the vertical height in an increasing number of systems, enabling the use of the vertical structure to decode the dynamical state of the…

The Hybrid Debris Disk Host Star HD 21997 is a High-Frequency Delta Scuti Pulsator
Aldo G. Sepulveda, Timothy R. Bedding, Simon J. Murphy +3
HD 21997 is host to a prototypical "hybrid" debris disk characterized by debris disk-like dust properties and a CO gas mass comparable to a protoplanetary disk. We use Transiting E…
