A planetary collision afterglow and transit of the resultant debris cloud
Matthew Kenworthy, Simon Lock, Grant Kennedy +19
Planets grow in rotating disks of dust and gas around forming stars, some of which can subsequently collide in giant impacts after the gas component is removed from the disk. Monit…
Inner edges of planetesimal belts: collisionally eroded or truncated?
Amaia Imaz Blanco, Sebastian Marino, Luca Matrà +9
The radial structure of debris discs can encode important information about their dynamical and collisional history. In this paper we present a 3-phase analytical model to analyse…
ALMA and Keck analysis of Fomalhaut field sources: JWST's Great Dust Cloud is a background object
Grant M. Kennedy, Joshua B. Lovell, Paul Kalas +1
At 7.7 pc, the A-type star Fomalhaut hosts a bright debris disk with multiple radial components. The disk is eccentric and misaligned, strongly suggesting that it is sculpted by in…
Morphology of the gas-rich debris disk around HD 121617 with SPHERE observations in polarized light

We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 m, and with t…
Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion
S. Hinkley, S. Lacour, G. -D. Marleau +110
Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…
The JWST Early Release Science Program for the Direct Imaging & Spectroscopy of Exoplanetary Systems
Sasha Hinkley, Aarynn L. Carter, Shrishmoy Ray +83
The direct characterization of exoplanetary systems with high contrast imaging is among the highest priorities for the broader exoplanet community. As large space missions will be…
A Star-sized Impact-Produced Dust Clump in the Terrestrial Zone of the HD 166191 System

We report on five years of 3-5 micron photometry measurements obtained by warm Spitzer to track the dust debris emission in the terrestrial zone of HD 166191 in combination with si…
ALMA's view of the M-dwarf GSC 07396-00759's edge-on debris disc: AU Mic's coeval twin
Patrick F. Cronin-Coltsmann, Grant M. Kennedy, Christian Adam +7
We present new ALMA Band 7 observations of the edge-on debris disc around the M1V star GSC 07396-00759. At ~20 Myr old and in the beta Pictoris Moving Group along with AU Mic, GSC…
Circumbinary disk evolution in the presence of an outer companion star
Rebecca G. Martin, Stephen Lepp, Stephen H. Lubow +3
We consider a hierarchical triple system consisting of an inner eccentric binary with an outer companion. A highly misaligned circumbinary disk around the inner binary is subject t…
Planet populations inferred from debris discs: insights from 178 debris systems in the ISPY, LEECH and LIStEN planet-hunting surveys
Tim D. Pearce, Ralf Launhardt, Robert Ostermann +11
We know little about the outermost exoplanets in planetary systems, because our detection methods are insensitive to moderate-mass planets on wide orbits. However, debris discs can…
Carbon monoxide gas produced by a giant impact in the inner region of a young system
Tajana Schneiderman, Luca Matrà, Alan P. Jackson +7
Models of terrestrial planet formation predict that the final stages of planetary assembly, lasting tens of millions of years beyond the dispersal of young protoplanetary disks, ar…
