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

Detection and characterization of exoplanets using projections on karhunen–loeve eigenimages: Forward modeling

L Pueyo - The Astrophysical Journal, 2016 - iopscience.iop.org
ABSTRACT A new class of high-contrast image analysis algorithms that empirically fit and
subtract systematic noise has lead to recent discoveries of faint exoplanet/substellar …

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 …

A primer on unifying debris disk morphologies

EJ Lee, E Chiang - The Astrophysical Journal, 2016 - iopscience.iop.org
ABSTRACT A" minimum model" for debris disks consists of a narrow ring of parent bodies,
secularly forced by a single planet on a possibly eccentric orbit, colliding to produce dust …

A narrow, edge-on disk resolved around HD 106906 with SPHERE

AM Lagrange, M Langlois, R Gratton, AL Maire… - Astronomy & …, 2016 - aanda.org
Context. HD 106906AB is the only young binary system so far around which a planet has
been imaged and a debris disk has been shown to exist, thanks to a strong IR excess. As …

Azimuthal asymmetries in the debris disk around HD 61005-A massive collision of planetesimals?

J Olofsson, M Samland, H Avenhaus… - Astronomy & …, 2016 - aanda.org
