An independent determination of Fomalhaut b’s orbit and the dynamical effects on the outer dust belt
The nearby star Fomalhaut harbours a cold, moderately eccentric dust belt with a sharp inner edge near 133 au. A low-mass, common proper motion companion (Fom b), was discovered near the inner edgeExpand

DUst around NEarby Stars. The survey observational results
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 Edgeworth-KuiperExpand

An Icy Kuiper-Belt Around the Young Solar-Type Star HD 181327
Context. HD 181327 is a young main sequence F5/F6 V star belonging to the beta Pictoris moving group (age similar to 12 Myr). It harbors an optically thin belt of circumstellar material at radiusExpand

Modeling the HD 32297 Debris Disk With Far-Infrared Herschel Data
HD 32297 is a young A-star ({approx}30 Myr) 112 pc away with a bright edge-on debris disk that has been resolved in scattered light. We observed the HD 32297 debris disk in the far-infrared andExpand

Morphology of the very inclined debris disk around HD 32297
Context. Direct imaging of circumstellar disks at high angular resolution is mandatory to provide morphological information that constrains their properties, in particular the spatial distribution ofExpand

Hot exozodiacal dust resolved around Vega with IOTA/IONIC
Context. Although debris discs have been detected around a significant number of main-sequence stars, only a few of them are known to harbour hot dust in their inner part where terrestrial planetsExpand

Herschel 's “cold debris disks”: background galaxies or quiescent rims of planetary systems?
Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100 μm or shorter. However, 6 out of 31 excess sources studied in the Herschel Open Time KeyExpand

A near-infrared interferometric survey of debris-disk stars - IV. An unbiased sample of 92 southern stars observed in H band with VLTI/PIONIER
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regions. Warm and hotExpand

Herschel-PACS observation of the 10 Myr old T Tauri disk TW Hya - Constraining the disk gas mass
Planets are formed in disks around young stars. With an age of similar to 10 Myr, TW Hya is one of the nearest T Tauri stars that is still surrounded by a relatively massive disk. In addition a largeExpand
