TL;DR: In this article, the authors observed 69 A3-F8 main sequence binary star systems using the Multiband Imaging Photometer for Spitzer onboard the Spitzer Space Telescope and found that approximately half of the excess emissions are derived from circumbinary planetesimal belts.

James Norwood,Heidi B. Hammel,Stefanie N. Milam,John Stansberry,Jonathan I. Lunine,Nancy J. Chanover,Dean C. Hines,George Sonneborn,Matthew S. Tiscareno,Michael E. Brown,Pierre Ferruit +10 more
TL;DR: The James Webb Space Telescope will enable a wealth of new scientific investigations in the near and mid-infrared, with sensitivity and spatial/spectral resolution greatly surpassing its predecessors as discussed by the authors.

TL;DR: The NIRCam for the James Webb Space Telescope is delivering the imagery that astronomers have hoped for ever since JWST was proposed back in the 1990s as mentioned in this paper , and it is exceeding pre-launch expectations in virtually all areas with very few surprises discovered in flight.

TL;DR: In this paper, the authors identify excess infrared emission, including a number of cases where the observed flux is more than 10 times brighter than the predicted photospheric flux, and interpret these signatures as evidence of debris disks in those systems.

TL;DR: In this article, the authors report 24 and/or 70 um measurements of ~160 A-type main-sequence stars using the Multiband Imaging Photometer for Spitzer (MIPS) and find that older stars tend to have lower fractional dust luminosity than younger ones.
