Debris disks: structure, composition, and variability

AM Hughes, G Duchêne… - Annual Review of …, 2018 - annualreviews.org
Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Non-negative matrix factorization: robust extraction of extended structures

B Ren, L Pueyo, GB Zhu, J Debes… - The Astrophysical …, 2018 - iopscience.iop.org
We apply the vectorized non-negative matrix factorization (NMF) method to the post-
processing of the direct imaging data of exoplanetary systems such as circumstellar disks …

Probing for exoplanets hiding in dusty debris disks: disk imaging, characterization, and exploration with HST/STIS multi-roll coronagraphy

G Schneider, CA Grady, DC Hines… - The Astronomical …, 2014 - iopscience.iop.org
Spatially resolved scattered-light images of circumstellar debris in exoplanetary systems

inclined ring with a high surface brightness. Past observations have raised several …

Planet populations inferred from debris discs-Insights from 178 debris systems in the ISPY, LEECH, and LIStEN planet-hunting surveys

TD Pearce, R Launhardt, R Ostermann… - Astronomy & …, 2022 - aanda.org
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 …

Maximizing the ExoEarth candidate yield from a future direct imaging mission

CC Stark, A Roberge, A Mandell… - The Astrophysical …, 2014 - iopscience.iop.org
ExoEarth yield is a critical science metric for future exoplanet imaging missions. Here we
estimate exoEarth candidate yield using single visit completeness for a variety of mission …

SONS: The JCMT legacy survey of debris discs in the submillimetre

WS Holland, BC Matthews, GM Kennedy… - Monthly Notices of …, 2017 - academic.oup.com
Debris discs are evidence of the ongoing destructive collisions between planetesimals, and
their presence around stars also suggests that planets exist in these systems. In this paper …
