Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

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 …

Many white dwarf stars show signs of having accreted smaller bodies, implying that they
may host planetary systems. A small number of these systems contain gaseous debris discs …

We report the results of a∼ 4 yr direct imaging survey of 104 stars to resolve and
characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager …

This paper uses observations of dusty debris discs, including a growing number of gas
detections in these systems, to test our understanding of the origin and evolution of this …

Debris disks are optically thin, almost gas-free dusty disks observed around a significant
fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short …

Abstract Recent Atacama Large Millimeter/submillimeter Array observations present
mounting evidence for the presence of exocometary gas released within Kuiper Belt analogs …

We observed a sample of 20 representative Herbig Ae/Be stars and 5 A-type debris discs
with PACS onboard Herschel, as part of the GAS in Protoplanetary Systems (GASPS) …

The gaseous molecular disk that orbits the main-sequence A-type star 49 Ceti has been
known since 1995, but the stellar age and the origin of the observed carbon monoxide …

The 30 Myr old A3-type star HD 21997 is one of the two known debris dust disks having a
measurable amount of cold molecular gas. With the goal of understanding the physical state …
