Debris disks around stars in the NIKA2 era [PDF]

open access: yesEPJ Web of Conferences, 2020
The new NIKA2 camera at the IRAM 30m radiotelescope was used to observe three known debris disks in order to constrain the SED of their dust emission in the millimeter wavelength domain.

Numerical Modeling of Dusty Debris Disks

open access: yesThe Astrophysical Journal, 2005
Infrared and submillimeter observations of nearby Vega-like stars have revealed a number of clumpy, asymmetric dust debris disks. Previous studies using semianalytical and numerical methods have suggested planetary companions of various mass as the likely cause of most examples of disk asymmetry.

A PRIMER ON UNIFYING DEBRIS DISK MORPHOLOGIES [PDF]

open access: yesThe Astrophysical Journal, 2016
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 grains that are perturbed by stellar radiation pressure.

The Apparent Absence of Forward Scattering in the HD 53143 Debris Disk

open access: yesThe Astrophysical Journal, 2023
HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold outer ring of planetesimals near 90 au. Unlike most other inclined debris disks imaged at visible wavelengths, the cold disk around HD 53143 appears as ...

THE FREQUENCY OF DEBRIS DISKS AT WHITE DWARFS [PDF]

open access: yesThe Astrophysical Journal, 2012
We present near- and mid-infrared photometry and spectroscopy from PAIRITEL, IRTF, and Spitzer of a metallicity-unbiased sample of 117 cool, hydrogen-atmosphere white dwarfs from the Palomar-Green survey and find five with excess radiation in the infrared, translating to a 4.3+2.7-1.2% frequency of debris disks.

Signposts of Multiple Planets in Debris Disks [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractWe review the nearby debris disk structures revealed by multi-wavelength images from Spitzer and Herschel, and complemented with detailed spectral energy distribution modeling. Similar to the definition of habitable zones around stars, debris disk structures should be identified and characterized in terms of dust temperatures rather than ...

Stability of liquid bridges between twisted elliptical disks [PDF]

open access: yes, 2005
The influence in the stability of long liquid bridges supported between two elliptical-shaped disks of their main axis relative orientation is investigated.

Millimeter Studies of Nearby Debris Disks

open access: yes, 2019
At least 20% of nearby main sequence stars are known to be surrounded by disks of dusty material resulting from the collisional erosion of planetesimals, similar to asteroids and comets in our own Solar System.

A catalog of collected debris disks: properties, classifications and correlations between disks and stars/planets [PDF]

open access: yes, 2023
We have collected a catalog of 1095 debris disks with properties and classification (resolved, planet, gas) information. From the catalog, we defined a less biased sample with 612 objects and presented the distributions of their stellar and disk ...
