Characteristics structure analysis on debris cloud in the hypervelocity impact of disk projectile on thin plate

Defence Technology, 2020
In this paper, the gauge points setting is introduced in the SPH simulation to analyze the debris cloud structure generated by the hypervelocity impact of disk projectile on thin plate.

THE DEBRIS DISK AROUND HR 8799 [PDF]

The Astrophysical Journal, 2009
We have obtained a full suite of Spitzer observations to characterize the debris disk around HR 8799 and to explore how its properties are related to the recently discovered set of three massive planets orbiting the star. We distinguish three components to the debris system: (1) warm dust (T ~150 K) orbiting within the innermost planet; (2) a broad ...

Dynamical Stability of Polar Circumbinary Orbits and Planet Formation in the Planetary Disk of 99 Herculis

The Astronomical Journal, 2023
A possible polar-ring debris disk, the dynamics of which can be described by the outer hierarchical restricted three-body problem, has been detected in 99 Herculis.

THE COLLISIONAL EVOLUTION OF DEBRIS DISKS [PDF]

The Astrophysical Journal, 2013
We explore the collisional decay of disk mass and infrared emission in debris disks. With models, we show that the rate of the decay varies throughout the evolution of the disks, increasing its rate up to a certain point, which is followed by a leveling off to a slower value. The total disk mass falls off ~ t^-0.35 at its fastest point (where t is time)

Hiding Dust around ϵ Eridani

The Astronomical Journal, 2023
With a Jupiter-like exoplanet and a debris disk with both asteroid and Kuiper Belt analogs, ϵ Eridani has a fascinating resemblance to our expectations for a young solar system.

Numerical Modeling of Dusty Debris Disks

The 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.

Planetesimals in Debris Disks [PDF]

, 2017
Planetesimals form in gas-rich protoplanetary disks around young stars. However, protoplanetary disks fade in about 10 Myr. The planetesimals (and also many of the planets) left behind are too dim to study directly. Fortunately, collisions between planetesimals produce dusty debris disks.
