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.

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 ...

Tribological behavior of heat treated AISI 6150 steel
Journal of Materials Research and Technology, 2020 This research presents an experimental study on the tribological behavior and plastic deformation layer response of quenched-tempered AISI 6150 steel and austempered AISI 6150 steel under sliding with a ball-on-disk type apparatus.

Debris Disk Evolution around A Stars [PDF]
The Astrophysical Journal, 2006 We report 24 and/or 70 um measurements of ~160 A-type main-sequence stars using the Multiband Imaging Photometer for Spitzer (MIPS). Their ages range from 5 to 850 Myr based on estimates from the literature (cluster or moving group associations) or from the H-R diagram and isochrones. The thermal infrared excess is identified by comparing the deviation

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 ...

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.
