Observing planet-disk interaction in debris disks [PDF]

Astronomy & Astrophysics, 2012
Context. Structures in debris disks induced by planetdisk interaction are promising to provide valuable constraints on the existence and properties of embedded planets. Aims.

Coplanar Circumbinary Debris Disks [PDF]

MNRAS, 2012
We present resolved Herschel images of circumbinary debris disks in the alpha CrB (HD139006) and beta Tri (HD13161) systems. We find that both disks are consistent with being aligned with the binary orbital planes.

Herschel Observations of Dusty Debris Disks [PDF]

The Astrophysical Journal, 2016
We present results from two Herschel observing programs using the Photodetector Array Camera and Spectrometer. During three separate campaigns, we obtained Herschel data for 24 stars at 70, 100, and 160 microns.

Debris disks around Sun-like stars [PDF]

The Astrophysical Journal, 2007
We have observed nearly 200 FGK stars at 24 and 70 microns with the Spitzer Space Telescope. We identify excess infrared emission, including a number of cases where the observed flux is more than 10 times brighter than the predicted photospheric flux ...

Debris Disks in NGC 2547 [PDF]

The Astrophysical Journal, 2007
We have surveyed the 30 Myr-old cluster NGC 2547 for planetary debris disks using Spitzer. At 4.5-8 um we are sensitive to the photospheric level down to mid-M stars (0.2 Msol) and at 24 um to early-G stars (1.2 Msol). We find only two to four stars with

Debris Disks: Probing Planet Formation [PDF]

, 2018
Debris disks are the dust disks found around ~20% of nearby main sequence stars in far-IR surveys. They can be considered as descendants of protoplanetary disks or components of planetary systems, providing valuable information on circumstellar disk ...

Searching for debris disks around isolated pulsars [PDF]

Planetary and Space Science, 2014
Different pieces of observational evidence suggest the existence of disks around isolated neutron stars. Such disks could be formed from supernova fallback when neutron stars are born in core-collapse supernova explosions. Efforts have been made to search for disks around different classes of pulsars, which include millisecond pulsars, young neutron ...

Polarization of Circumstellar Debris Disk Light Echoes

The Astronomical Journal
Light echoes of debris disks around active stars can reveal disk structure and composition even when disks are not spatially resolved. Unfortunately, distinguishing reflected light from quiescent starlight and unexpected post-peak flare structure is ...

A Constraint on the Amount of Hydrogen from the CO Chemistry in Debris Disks

The Astrophysical Journal, 2023
The faint CO gases in debris disks are easily dissolved into C by UV irradiation, while CO can be reformed via reactions with hydrogen. The abundance ratio of C/CO could thus be a probe of the amount of hydrogen in the debris disks.
