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
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
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 …

Exocometary gas in the HD 181327 debris ring
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 …

The debris disk around HR 8799
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
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 …
