Chemical abundances of giant stars in the Crater stellar system
P. Bonifacio, E. Caffau, S. Zaggia +4
We obtained spectra for two giants of Crater (Crater J113613-105227 and Crater J113615-105244) using X-Shooter at the VLT. The spectra have been analysed with the MyGIsFoS code usi…
Limb darkening and exoplanets: testing stellar model atmospheres and identifying biases in transit parameters
Néstor Espinoza, Andrés Jordán
Limb-darkening is fundamental in determining transit lightcurve shapes, and is typically modeled by a variety of laws that parametrize the intensity profile of the star that is bei…
On the environments of type Ia supernovae within host galaxies
J. P. Anderson, P. A. James, F. Förster +4
We present constraints on supernovae type Ia (SNe~Ia) progenitors through an analysis of the environments found at the explosion sites of 102 events within star-forming host galaxi…
A multi-wavelength view on the dusty Wolf-Rayet star WR 48a
Svetozar A. Zhekov, Toma Tomov, Marcin P. Gawronski +5
We present results from the first attempts to derive various physical characteristics of the dusty Wolf-Rayet star WR 48a based on a multi-wavelength view of its observational prop…
Discovery of a new Y dwarf: WISE J030449.03-270508.3
D. J. Pinfield, M. Gromadzki, S. K. Leggett +21
We present a new Y dwarf, WISE J030449.03-270508.3, confirmed from a candidate sample designed to pick out low temperature objects from the WISE database. The new object is typed Y…
The Gaia-ESO Survey: Stellar content and elemental abundances in the massive cluster NGC 6705
T. Cantat-Gaudin, A. Vallenari, S. Zaggia +52
Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple population…
