Stumbling over planetary building blocks: AU Microscopii as an example of the challenge of retrieving debris-disk dust properties
Jessica A. Arnold, Alycia J. Weinberger, Gorden Videen +1
We explore whether assumptions about dust grain shape affect resulting estimates of the composition and grain size distribution of the AU Microscopii (AU Mic) debris disk from scat…
Optical constants of a solar system organic analog and the Allende meteorite in the near and mid-infrared (1.5-13 μm)
Jessica A. Arnold, Alycia J. Weinberger, George Cody +2
Measurements of visible and near-infrared reflection (0.38-5 μm) and mid to far infrared emission (5-200 μm) from telescope and satellite remote sensing instruments make it possibl…
Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
Studying the Evolution of Warm Dust Encircling BD +20 307 Using SOFIA
Maggie A. Thompson, Alycia J. Weinberger, Luke Keller +2
The small class of known stars with unusually warm, dusty debris disks is a key sample to probe in order to understand cascade models and extreme collisions that likely lead to the…
The effect of dust composition and shape on radiation-pressure forces and blowout sizes of particles in debris disks
Jessica A. Arnold, Alycia J. Weinberger, Gorden Videen +1
The light scattered from dust grains in debris disks is typically modeled as compact spheres using Lorenz-Mie theory or as porous spheres by incorporating an effective medium theor…
CASTAway: An Asteroid Main Belt Tour and Survey
N. E. Bowles, C. Snodgrass, A Gibbings +42
CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the c…
