The Age of the Carina Young Association and Potential Membership of HD 95086
Mark Booth, Carlos del Burgo, Valeri V. Hambaryan
Carina is a nearby young stellar association. So far, only a small number of stars have been clearly identified as members of this association. In this paper we reanalyse the membe…

We present updated parameters for the star HD 209458 and its transiting giant planet. The stellar angular diameter =0.22540.0017 mas is obtained from the average ratio betw…
Incidence of debris discs around FGK stars in the solar neighbourhood
B. Montesinos, C. Eiroa, A. V. Krivov +16
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
New bright optical spectrophotometric standards: A-type stars from the STIS Next Generation Spectral Library
Carlos Allende Prieto, Carlos del Burgo
Exoplanets have sparked interest in extremely high signal-to-noise ratio spectroscopic observations of very bright stars, in a regime where flux calibrators, in particular DA white…
ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength
R. Liseau, W. Vlemmings, A. Bayo +19
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…
Spectroscopic signatures of youth in low-mass kinematic candidates of young moving groups
M. C. Gálvez-Ortiz, M. Kuznetsov, J. R. A. Clarke +12
We present a study of age-related spectral signatures observed in 25 young low-mass objects that we have previously determined as possible kinematic members of five young moving gr…
Potential multi-component structure of the debris disk around HIP 17439 revealed by Herschel/DUNES
S. Ertel, J. P. Marshall, J. -C. Augereau +16
[abridged] Aims. Our Herschel Open Time Key Programme DUNES aims at detecting and characterizing debris disks around nearby, sun-like stars. In addition to the statistical analysis…
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…
Stellar Magnetism and starspots: the implications for exoplanets
Conrad Vilela, John Southworth, Carlos del Burgo
Stellar variability induce by starspots can hamper the detection of exoplanets and bias planet property estimations. These features can also be used to study star-planet interactio…
DUst Around NEarby Stars. The survey observational results
C. Eiroa, J. P. Marshall, A. Mora +47
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
