Circumstellar disks of planetary debris are now known or suspected to closely orbit
hundreds of white dwarf stars. To date, both data and theory support disks that are entirely …

The measurement of precise absolute fluxes for stellar sources has been pursued with
increased vigor since the discovery of dark energy and the realization that its detailed …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

Evidence is now compelling that elements heavier than helium in many white dwarf
atmospheres have accumulated by accretion from orbiting rocky bodies, often larger than …

Infrared studies have revealed debris likely related to planet formation in orbit around∼ 30%
of youthful, intermediate mass, main-sequence stars. We present evidence, based on …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

Planetary debris disks around other stars are analogous to the asteroid and Kuiper belts in
the Solar System. Their structure reveals the configuration of small bodies and provides …

Context. Debris discs are a consequence of the planet formation process and constitute the
fingerprints of planetesimal systems. Their solar system counterparts are the asteroid and …

This paper presents a study of circumstellar debris around Sun-like stars using data from the
Herschel DEBRIS Key Programme. DEBRIS is an unbiased survey comprising the nearest∼ …
