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 …

Evolution of debris disks

MC Wyatt - Annu. Rev. Astron. Astrophys., 2008 - annualreviews.org
Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

A planet within the debris disk around the pre-main-sequence star AU Microscopii

P Plavchan, T Barclay, J Gagné, P Gao, B Cale… - Nature, 2020 - nature.com
Abstract AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a
distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively …

Optical images of an exosolar planet 25 light-years from Earth

P Kalas, JR Graham, E Chiang, MP Fitzgerald… - science, 2008 - science.org
Fomalhaut, a bright star 7.7 parsecs (25 light-years) from Earth, harbors a belt of cold dust
with a structure consistent with gravitational sculpting by an orbiting planet. Here, we present …

Debris disk results from the Gemini Planet Imager Exoplanet Survey's polarimetric imaging campaign

TM Esposito, P Kalas, MP Fitzgerald… - The Astronomical …, 2020 - iopscience.iop.org
We report the results of a∼ 4 yr direct imaging survey of 104 stars to resolve and
characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager …

Exocometary gas in the HD 181327 debris ring

S Marino, L Matrà, C Stark, MC Wyatt… - Monthly Notices of …, 2016 - academic.oup.com
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 …

Polarimetry with the Gemini planet imager: methods, performance at first light, and the circumstellar ring around HR 4796A

MD Perrin, G Duchene, M Millar-Blanchaer… - The Astrophysical …, 2015 - iopscience.iop.org
We present the first results from the polarimetry mode of the Gemini Planet Imager (GPI),
which uses a new integral field polarimetry architecture to provide high contrast linear …

The debris disk around HR 8799

KYL Su, GH Rieke, KR Stapelfeldt… - The Astrophysical …, 2009 - iopscience.iop.org
We have obtained a full suite of Spitzer observations to characterize the debris disk around
HR 8799 and to explore how its properties are related to the recently discovered set of three …

Debris disks: seeing dust, thinking of planetesimals and planets

AV Krivov - Research in Astronomy and Astrophysics, 2010 - iopscience.iop.org
Debris disks are optically thin, almost gas-free dusty disks observed around a significant
fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short …

Fomalhaut's debris disk and planet: constraining the mass of Fomalhaut b from disk morphology

E Chiang, E Kite, P Kalas, JR Graham… - The Astrophysical …, 2009 - iopscience.iop.org
Following the optical imaging of exoplanet candidate Fomalhaut b (Fom b), we present a
numerical model of how Fomalhaut's debris disk is gravitationally shaped by a single interior …
