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 - terrestrial planet connection [PDF]
Proceedings of the International Astronomical Union, 2011 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.

Polarization of Circumstellar Debris Disk Light Echoes
The Astronomical JournalLight echoes of debris disks around active stars can reveal disk structure and composition even when disks are not spatially resolved. Unfortunately, distinguishing reflected light from quiescent starlight and unexpected post-peak flare structure is ...

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 ...

BINARIES AMONG DEBRIS DISK STARS [PDF]
The Astrophysical Journal, 2012 We have gathered a sample of 112 main-sequence stars with known debris disks. We collected published information and performed adaptive optics observations at Lick Observatory to determine if these debris disks are associated with binary or multiple stars.

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.

Primordial or Secondary? Testing Models of Debris Disk Gas with ALMA
The Astrophysical Journal, 2023 The origin and evolution of gas in debris disks are still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed.
