Dusty circumstellar disks

B Zuckerman - Annual Review of Astronomy and Astrophysics, 2001 - annualreviews.org
▪ Abstract Dusty circumstellar disks in orbit around main-sequence stars were discovered in
1983 by the infrared astronomical satellite. It was the first time material that was not another …

Transience of hot dust around sun-like stars

MC Wyatt, R Smith, JS Greaves… - The Astrophysical …, 2007 - iopscience.iop.org
In this paper a simple model for the steady state evolution of debris disks due to collisions is
developed and confronted with the properties of the emerging population of seven Sun-like …

Collisional processes in extrasolar planetesimal discs–dust clumps in Fomalhaut's debris disc

MC Wyatt, WRF Dent - Monthly Notices of the Royal …, 2002 - academic.oup.com
This paper presents a model for the outcome of collisions between planetesimals in a debris
disc, and assesses the impact of collisional processes on the structure and size distribution …

Spitzer IRS spectroscopy of IRAS-discovered debris disks

CH Chen, BA Sargent, C Bohac, KH Kim… - The Astrophysical …, 2006 - iopscience.iop.org
Abstract We have obtained Spitzer Space Telescope Infrared Spectrograph (IRS) 5.5-35 μm
spectra of 59 main-sequence stars that possess IRAS 60 μm excess. The spectra of five …

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 …

Variations on Debris Disks: Icy Planet Formation at 30-150 AU for 1-3 M☉ Main-Sequence Stars

SJ Kenyon, BC Bromley - The Astrophysical Journal Supplement …, 2008 - iopscience.iop.org
We describe calculations for the formation of icy planets and debris disks at 30-150 AU
around 1-3 M⊙ stars. Debris disk formation coincides with the formation of planetary …

Evolution of circumstellar disks around normal stars: placing our solar system in context

MR Meyer, DE Backman, AJ Weinberger… - arXiv preprint astro-ph …, 2006 - arxiv.org
Over the past 10 years abundant evidence has emerged that many (if not all) stars are born
with circumstellar disks. Understanding the evolution of post-accretion disks can provide …

The complete census of 70 μm-bright debris disks within “the formation and evolution of planetary systems” Spitzer legacy survey of sun-like stars

LA Hillenbrand, JM Carpenter, JS Kim… - The Astrophysical …, 2008 - iopscience.iop.org
We report detection of cool dust surrounding solar-type stars from observations performed
as part of the Spitzer Legacy Science Program FEPS. From a sample of 328 stars having …

The near-sun dust environment: initial observations from parker solar probe

JR Szalay, P Pokorný, SD Bale… - The Astrophysical …, 2020 - iopscience.iop.org
Abstract The Parker Solar Probe (PSP) spacecraft has flown into the densest, previously
unexplored, innermost region of our solar system's zodiacal cloud. While PSP does not have …

Dust distributions in debris disks: effects of gravity, radiation pressure and collisions

AV Krivov, T Löhne, M Sremčević - Astronomy & Astrophysics, 2006 - aanda.org
We model a typical debris disk, treated as an idealized ensemble of dust particles, exposed
to stellar gravity and direct radiation pressure and experiencing fragmenting collisions …
