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…
Hubble Space Telescope Optical Imaging of the Eroding Debris Disk HD 61005
H. L. Maness, P. Kalas, K. M. G. Peek +7
We present Hubble Space Telescope optical coronagraphic polarization imaging observations of the dusty debris disk HD 61005. The scattered light intensity image and polarization st…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
High resolution ALMA and HST imaging of CrB: a broad debris disc around a post-main sequence star with low-mass companions
J. B. Lovell, M. C. Wyatt, P. Kalas +6
CrB is a Gyr old K1 sub-giant star, with an eccentric exo-Jupiter at au and a debris disc at tens of au. We present ALMA Band 6 (mm) and HST sc…
The Scuti pulsations of Pictoris as observed by ASTEP from Antarctica
D. Mékarnia, E. Chapellier, T. Guillot +13
The Antartica Search for Transiting Extrasolar Planets (ASTEP), an automatized 400 mm telescope located at Concordia station in Antarctica, monitored beta Pictoris continuously to…
99 Herculis: Host to a Circumbinary Polar-ring Debris Disk
G. M. Kennedy, M. C. Wyatt, B. Sibthorpe +6
We present resolved Herschel images of a circumbinary debris disk in the 99 Herculis system. The primary is a late F-type star. The binary orbit is well characterised and we conclu…
