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.

HERSCHEL OBSERVATIONS OF DUSTY DEBRIS DISKS [PDF]
The Astrophysical Journal, 2016 ABSTRACT 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 μm. We chose stars that were already known or suspected to have circumstellar dust based on excess infrared (IR) emission ...

The debris disk – terrestrial planet connection [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractThe eccentric orbits of the known extrasolar giant planets provide evidence that most planet-forming environments undergo violent dynamical instabilities. Here, we numerically simulate the impact of giant planet instabilities on planetary systems as a whole.

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 ...

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. We investigate the observability of structures in debris disks induced by planet-disk interaction. Methods.

AN ATCA SURVEY OF DEBRIS DISKS AT 7 MILLIMETERS [PDF]
The Astrophysical Journal, 2015 We present Australia Telescope Compact Array continuum observations at a wavelength of 6.8 mm of five debris disks: β Pictoris, q1 Eridani, HD 107146, HD 181327, and HD 95086. These observations provide the detection at the longest wavelengths obtained to date for all these debris disks.

Advanced Engineering Materials, EarlyView.Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...
