B fields in OB stars (BOB): on the detection of weak magnetic fields in the two early B-type stars beta CMa and epsilon CMa
L. Fossati, N. Castro, T. Morel +15
Within the context of the "B fields in OB stars (BOB)" collaboration, we used the HARPSpol spectropolarimeter to observe the early B-type stars beta CMa (HD44743; B1 II/III) and ep…
On the consistency of magnetic field measurements of Ap stars: lessons learned from the FORS1 archive
J. D. Landstreet, S. Bagnulo, L. Fossati
CONTEXT. The ESO archive of FORS1 spectropolarimetric observations may be used to create a homogeneous database of magnetic field measurements. However, no systematic comparison of…
Tracing early stellar evolution with asteroseismology: pre-main sequence stars in NGC 2264
Konstanze Zwintz, Luca Fossati, Tatiana Ryabchikova +2
Asteroseismology has been proven to be a successful tool to unravel details of the internal structure for different types of stars in various stages of their main sequence and post…
An In-Depth Spectroscopic Analysis of RR Lyr Variations over the Pulsation Cycle
L. Fossati, K. Kolenberg, D. V. Shulyak +5
The stellar parameters of RR Lyrae stars vary considerably over a pulsation cycle, and their determination is crucial for stellar modelling. We present a detailed spectroscopic ana…
The spectroscopic Hertzsprung-Russell diagram of Galactic massive stars
N. Castro, L. Fossati, N. Langer +3
The distribution of stars in the Hertzsprung-Russell diagram narrates their evolutionary history and directly assesses their properties. Placing stars in this diagram however requi…
The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
M. Cappetta, R. P. Saglia, J. L. Birkby +35
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in…
