Alignment in star-debris disc systems seen by Herschel
J. S. Greaves, G. M. Kennedy, N. Thureau +28
Many nearby main-sequence stars have been searched for debris using the far-infrared Herschel satellite, within the DEBRIS, DUNES and Guaranteed-Time Key Projects. We discuss here…
Herschel's "Cold Debris Disks": Background Galaxies or Quiescent Rims of Planetary Systems?
A. V. Krivov, C. Eiroa, T. Löhne +24
(abridged) Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100μm or shorter. However, six out of 31 excess sources in the Hersc…
Gas and dust in the TW Hydrae Association as seen by the Herschel Space Observatory
P. Riviere-Marichalar, C. Pinte, D. Barrado +15
Context. Circumstellar discs are the places where planets form, therefore knowledge of their evolution is crucial for our understanding of planet formation. The Herschel Space Obse…
GASPS - a Herschel survey of gas and dust in Protoplanetary Disks: Summary and Initial Statistics
W. R. F. Dent, W. F. Thi, I. Kamp +47
GASPS is a far-infrared line and continuum survey of protoplanetary and young debris disks using PACS on the Herschel Space Observatory. The survey includes [OI] at 63 microns, as…
DUst Around NEarby Stars. The survey observational results
C. Eiroa, J. P. Marshall, A. Mora +47
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
Identification of transitional disks in Chamaeleon with Herschel
Á. Ribas, B. Merín, H. Bouy +11
Transitional disks are circumstellar disks with inner holes that in some cases are produced by planets and/or substellar companions in these systems. For this reason, these disks a…
