Evolution of Debris Disks
TLDR
In this article, a review describes the theoretical framework within which debris disk evolution takes place and shows how that framework has been constrained by observations, including infrared photometry of large numbers of debris disks, providing snapshots of the dust present at different evolutionary phases.Abstract:
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 continuously replenished through collisions between planetesimals in belts analogous to the Solar System’s asteroid and Kuiper belts, or in collisions between growing protoplanets. The evolution of a star’s debris disk is indicative of the evolution of its planetesimal belts and may be influenced by planet formation processes, which can continue throughout the first gigayear as the planetary system settles to a stable configuration and planets form at large radii. Evidence for that evolution comes from infrared photometry of large numbers of debris disks, providing snapshots of the dust present at different evolutionary phases, as well as from images of debris disk structure. This review describes the theoretical framework within which debris disk evolution takes place and shows how that framework has been constrained by observations.read more

Density waves in debris discs and galactic nuclei
TL;DR: In this paper, the linear perturbations of collisionless near-Keplerian disks were studied and it was shown that these disks can support large-scale "slow" modes, in which the frequency is proportional to the disc mass.

Resolved Millimeter-Wavelength Observations of Debris Disks around Solar-Type Stars
Amy Steele,A. Meredith Hughes,John M. Carpenter,Angelo Ricarte,Sean M. Andrews,David J. Wilner,Eugene Chiang +6 more
TL;DR: In this article, the presence of debris disks around young main sequence stars with millimeter flux suitable for interferometric follow-up has been investigated using the Submillimeter Array (SMA) and the Combined Array for Research in Millimeter-wave Astronomy (CARMA).
Collisional Fragmentation Is Not a Barrier to Close-in Planet Formation
TL;DR: In this article, it was shown that even differentiated bodies can accumulate to form planets at distances that are not much larger than the Roche radius of the host star, and that the collisional fragmentation is not a barrier to rocky planet formation.

TL;DR: In this paper, the authors present new X-ray observations, optical spectroscopy, near-IR interferometry, and mid-IR photometry of this system to constrain its parameters and further explore the cause of dust mass loss.

Detection and Characterization of Extrasolar Planets through Mean-Motion Resonances. II. The Effect of the Planet's Orbital Eccentricity on Debris Disk Structures
Maryam Tabeshian,Paul Wiegert +1 more
TL;DR: In this article, the authors extend their work to systems in which the perturbing planet has moderate orbital eccentricity, a common occurrence in exoplanetary systems, and find that the widths, locations, and shapes of two prominent structures, the 2:1 and 3:1 MMRs, could be used to determine the mass, semimajor axis, and eccentricity of the planetary perturber and present an algorithm for doing so.
