Signposts of Multiple Planets in Debris Disks [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractWe review the nearby debris disk structures revealed by multi-wavelength images from Spitzer and Herschel, and complemented with detailed spectral energy distribution modeling. Similar to the definition of habitable zones around stars, debris disk structures should be identified and characterized in terms of dust temperatures rather than ...

Massive Debris Disks May Hinder Secular Stirring by Planetary Companions: An Analytic Proof of Concept

The Astrophysical Journal
Debris disks or exo-Kuiper belts, detected through their thermal or scattered emission from their dusty components, are ubiquitous around main-sequence stars.

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

Astronomy & Astrophysics
Context. Debris disks – collisionally sustained belts of dust and sometimes gas around main sequence stars – are remnants of planet formation processes and are found in systems ≳10 Myr old.

Dusty OB stars in the Small Magellanic Cloud - II: Extragalactic Disks or Examples of the Pleiades Phenomenon?

, 2013
We use mid-infrared Spitzer spectroscopy and far-infrared Herschel photometry for a sample of twenty main sequence O9--B2 stars in the Small Magellanic Cloud (SMC) with strong 24 micron excesses to investigate the origin of the mid-IR emission.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Frequencies of Warm Debris Disks Based on Point Source Catalogs of Spitzer, WISE, and Gaia

The Astronomical Journal
More than a thousand warm debris disks have been detected as infrared excess at mid-infrared wavelengths, and their frequencies have been obtained for various spectral types of stars.

The Kuiper Belt and Other Debris Disks

, 2008
We discuss the current knowledge of the Solar system, focusing on bodies in the outer regions, on the information they provide concerning Solar system formation, and on the possible relationships that may exist between our system and the debris disks of ...

The Exceptionally Large Debris Disk around γ Ophiuchi [PDF]

The Astrophysical Journal, 2008
Spitzer images resolve the debris disk around Ophiuchi at both 24 and 70 um. The resolved images suggest a disk radius of ~520 AU at 70 um and >=260 AU at 24 um. The images, along with a consistent fit to the spectral energy distribution of the disk from 20 to 350 um, show that the primary disk structure is inclined by ~50 degree from the plane of
