Multiple Rings of Millimeter Dust Emission in the HD 15115 Debris Disk
Meredith A. MacGregor, Alycia J. Weinberger, Erika R. Nesvold +8
We present observations of the HD 15115 debris disk from ALMA at 1.3 mm that capture this intriguing system with the highest resolution ( or AU) at mil…
The Deflector Selector: A Machine Learning Framework for Prioritizing Hazardous Object Deflection Technology Development
Erika R. Nesvold, Adam Greenberg, Nicolas Erasmus +4
Several technologies have been proposed for deflecting a hazardous Solar System object on a trajectory that would otherwise impact the Earth. The effectiveness of each technology d…
Finding the Needles in the Haystacks: High-Fidelity Models of the Modern and Archean Solar System for Simulating Exoplanet Observations
Aki Roberge, Maxime J. Rizzo, Andrew P. Lincowski +10
We present two state-of-the-art models of the solar system, one corresponding to the present day and one to the Archean Eon 3.5 billion years ago. Each model contains spatial and s…
HD 106906: A Case Study for External Perturbations of a Debris Disk
Erika R. Nesvold, Smadar Naoz, Michael Fitzgerald
Models of debris disk morphology are often focused on the effects of a planet orbiting interior to or within the disk. Nonetheless, an exterior planetary-mass perturber can also ex…
Exocometary gas in the HD 181327 debris ring
S. Marino, L. Matra, C. Stark +14
An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now we only knew of cases around A stars. Here we present the first d…
