Herschel PACS and SPIRE observations of blazar PKS 1510-089: a case for two blazar zones
Krzysztof Nalewajko, Marek Sikora, Greg M. Madejski +5
We present the results of observations of blazar PKS 1510-089 with the Herschel Space Observatory PACS and SPIRE instruments, together with multiwavelength data from Fermi/LAT, Swi…
The orbits of subdwarf B + main-sequence binaries. I: The sdB+G0 system PG 1104+243
J. Vos, R. H. Östensen, P. Degroote +18
The predicted orbital period histogram of an sdB population is bimodal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, there are many short-period…
A VLT VIMOS IFU study of the ionisation nebula surrounding the Supersoft X-ray Source CAL 83
Pieter Gruyters, Katrina Exter, Timothy P. Roberts +1
CAL83 is a prototype of the class of Super Soft X-ray Sources (SXS). It is a binary consisting of a low mass secondary that is transferring mass onto a white dwarf primary and is t…
Herschel images of Fomalhaut. An extrasolar Kuiper Belt at the height of its dynamical activity
B. Acke, M. Min, C. Dominik +33
Fomalhaut is a young, nearby star that is suspected to harbor an infant planetary system, interspersed with one or more belts of dusty debris. We present far-infrared images obtain…
Mass ratio from Doppler beaming and Rømer delay versus ellipsoidal modulation in the Kepler data of KOI-74
S. Bloemen, T. R. Marsh, P. Degroote +18
We present a light curve analysis and radial velocity study of KOI-74, an eclipsing A star + white dwarf binary with a 5.2 day orbit. Aside from new spectroscopy covering the orbit…
Absolute dimensions of solar-type eclipsing binaries. EF Aquarii: a G0 test for stellar evolution models
J. Vos, J. V. Clausen, U. G. Jørgensen +4
Recent studies have shown that stellar chromospheric activity, and its effect on convective energy transport in the envelope, is most likely the cause of significant radius and tem…
