Multi-wavelength, spatially resolved modelling of HD 48682's debris disc
S. Hengst, J. P. Marshall, J. Horner +1
Asteroids and comets (planetesimals) are created in gas- and dust-rich protoplanetary discs. The presence of these planetesimals around main-sequence stars is usually inferred from…
The Pan-Pacific Planet Search VII: The most eccentric planet orbiting a giant star
Robert A. Wittenmyer, M. I. Jones, Jonathan Horner +9
Radial velocity observations from three instruments reveal the presence of a 4 M_jup planet candidate orbiting the K giant HD 76920. HD 76920b has an orbital eccentricity of 0.856$…
A Herschel resolved debris disc around HD 105211
S. Hengst, J. P. Marshall, J. Horner +1
Debris discs are the dusty aftermath of planet formation processes around main-sequence stars. Analysis of these discs is often hampered by the absence of any meaningful constraint…
A DEBRIS Disk Around The Planet Hosting M-star GJ581 Spatially Resolved with Herschel
J. -F. Lestrade, B. C. Matthews, B. Sibthorpe +17
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 di…
A Dynamical Analysis of the Proposed Circumbinary HW Virginis Planetary System
J. Horner, T. C. Hinse, R. A. Wittenmyer +2
In 2009, the discovery of two planets orbiting the evolved binary star system HW Virginis was announced, based on systematic variations in the timing of eclipses between the two st…
Herschel imaging of 61 Vir: implications for the prevalence of debris in low-mass planetary systems
M. C. Wyatt, G. Kennedy, B. Sibthorpe +15
This paper describes Herschel observations of the nearby (8.5pc) G5V multi-exoplanet host star 61 Vir at 70-500micron carried out by the DEBRIS survey. These reveal emission that i…
