We present Herschel spatially resolved images of the debris disc orbiting the subgiant κ Coronae Borealis (κ CrB). Not only are these the first resolved images of a debris disc orbiting a subgiant, but κ CrB is a rare example of an intermediate mass star where a detailed study of the structure of the planetary system can be made, including both planets and planetesimal belt(s). The only way to discover planets using the radial velocity technique around such stars is to observe ‘retired’ A stars…

Herschel observations of debris discs orbiting planet-hosting subgiants

Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial velocity detected

ALMA observations of the nearby AGB star L2 Puppis - I. Mass of the central star and detection of a candidate planet

Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evolution will impact


We present dual-band Herschel/Photodetector Array Camera and Spectrometer imaging for four stars whose spectral energy distributions (SEDs) suggest two-ring disk architectures that mirror that of the

Potential multi-component structure of the debris disk around HIP 17439 revealed by Herschel/DUNES ⋆

Context. The dust observed in debris disks is produced through collisions of larger bodies left over from the planet/planetesimal formation process. Spatially resolving these disks permits to

Stirring in massive, young debris discs from spatially resolved Herschel images

A significant fraction of main-sequence stars are encircled by dusty debris discs, where the short-lived dust particles are replenished through collisions between planetesimals. Most destructive

A near-infrared interferometric survey of debris-disc stars - III. First statistics based on 42 stars observed with CHARA/FLUOR

Context. Dust is expected to be ubiquitous in extrasolar planetary systems owing to the dynamical activity of minor bodies. Inner dust populations are, however, still poorly known because of the high


The radii of debris disks and the sizes of their dust grains are important tracers of the planetesimal formation mechanisms and physical processes operating in these systems. Here we use a

On Lifetimes of Dusty Debris Disks around A-type Stars

Abstract Using a collection of 40 debris disks (DD) around dwarf A-type stars (from which 17 are spatially resolved) having well determined stellar ages (Vican 2012), we found that for a collisional

Far-infrared and sub-millimetre imaging of HD 76582's circumstellar disc

Debris discs, the tenuous rocky and icy remnants of planet formation, are believed to be evidence for planetary systems around other stars. The JCMT/SCUBA-2 debris disc legacy survey ‘SCUBA-2

A near-infrared interferometric survey of debris-disk stars

Context. Hot exozodiacal dust has been shown to be present in the innermost regions of an increasing number of main sequence stars over the past 15 yr. However, the origin of hot exozodiacal dust and



A DEBRIS disk around the planet hosting M-star GJ 581 spatially resolved with Herschel

Debris disks have been found primarily around intermediate and solar mass stars (spectral types A-K) but rarely around low mass M-type stars. We have spatially resolved a debris disk around the

Images of a fourth planet orbiting HR 8799

The HR 8799 planetary system, with its four young giant planets and known cold/warm debris belts, is a unique laboratory in which to study the formation and evolution of giant planets at wide (>10 au) separations.


We have obtained a full suite of Spitzer observations to characterize the debris disk around HR 8799 and to explore how its properties are related to the recently discovered set of three massive

We report precise Doppler measurements of two stars, obtained at Lick Observatory as part of our search for planets orbiting intermediate-mass subgiants. Periodic variations in the radial velocities

Resolved debris discs around A stars in the Herschel DEBRIS survey

The majority of debris discs discovered so far have only been detected through infrared excess emission above stellar photospheres. While disc properties can be inferred from unresolved photometry

Direct Imaging of Multiple Planets Orbiting the Star HR 8799

High-contrast observations with the Keck and Gemini telescopes have revealed three planets orbiting the star HR 8799, with projected separations of 24, 38, and 68 astronomical units.

Resolved imaging of the HD 191089 debris disc

Two-thirds of the F star members of the 12 Myr old β Pictoris moving group (BPMG) show significant excess emission in the mid-infrared, several million years after the expected dispersal of the

We use a multiannulus planetesimal accretion code to investigate the growth of icy planets in the outer regions of a planetesimal disk. In a quiescent minimum-mass solar nebula, icy planets grow to
