Formation of Gaps in Self-gravitating Debris Disks by Secular Resonance in a Single-planet System. II. Toward a Self-consistent Model

The Astrophysical Journal, 2023
High-resolution observations of several debris disks reveal structures such as gaps and spirals, suggestive of gravitational perturbations induced by underlying planets.

Abundances in Stars with Debris Disks [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractWe present preliminary results of a detailed chemical abundance analysis for a sample of solar-type stars known to exhibit excess infrared emission associated with dusty debris disks. Our sample of 28 stars was selected based on results from the Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy Program, for the purpose of ...

AKARI?IRC Survey of Hot Debris Disks

, 2009
As a result of IRAS observations, main-sequence stars that have circumstellar debris disks and thus show infrared excess have been discovered. Since debris disks are thought to be the final stage of planet formation, it is very important to investigate ...

Massive Debris Disks May Hinder Secular Stirring by Planetary Companions: An Analytic Proof of Concept

The Astrophysical Journal
Debris disks or exo-Kuiper belts, detected through their thermal or scattered emission from their dusty components, are ubiquitous around main-sequence stars.

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

Astronomy & Astrophysics
Context. Debris disks – collisionally sustained belts of dust and sometimes gas around main sequence stars – are remnants of planet formation processes and are found in systems ≳10 Myr old.

Evidence for Misalignment between Debris Disks and Their Host Stars

The Astrophysical Journal, 2023
We place lower limits on the obliquities between debris disks and their host stars for 31 systems by comparing their disk and stellar inclinations.

Transient dust in warm debris disks

, 2012
Context. Debris disks trace remnant reservoirs of leftover planetesimals in planetary systems. In the past years, a handful of “warm” debris disks have been discovered in which emission in excess starts in the mid-infrared. An interesting subset of these

Frequencies of Warm Debris Disks Based on Point Source Catalogs of Spitzer, WISE, and Gaia

The Astronomical Journal
More than a thousand warm debris disks have been detected as infrared excess at mid-infrared wavelengths, and their frequencies have been obtained for various spectral types of stars.
