Li abundances in F stars: planets, rotation and galactic evolution
E. Delgado Mena, S. Bertrán de Lis, V. Zh. Adibekyan +7
We find that hot jupiter host stars within the T range 5900-6300K show lower Li abundances, by 0.14 dex, than stars without detected planets. This offset has a signi…
The evolution of the cold interstellar medium in galaxies following a starburst
K. Rowlands, V. Wild, N. Nesvadba +4
We present the evolution of dust and molecular gas properties in a sample of 11 starburst to post-starburst (PSB) galaxies selected to span an age sequence from ongoing…
BGLS: A Bayesian formalism for the generalised Lomb-Scargle periodogram
A. Mortier, J. P. Faria, C. M. Correia +2
Context. Frequency analyses are very important in astronomy today, not least in the ever-growing field of exoplanets, where short-period signals in stellar radial velocity data are…
Correcting the spectroscopic surface gravity using transits and asteroseismology. No significant effect on temperatures or metallicities with ARES+MOOG in LTE
A. Mortier, S. G. Sousa, V. Zh. Adibekyan +2
Precise stellar parameters are crucial for several reasons, amongst which are the precise characterization of orbiting exoplanets and the correct determination of galactic chemical…
Spectroscopic parameters for solar-type stars with moderate/high rotation. New parameters for 10 planet-hosts
M. Tsantaki, S. G. Sousa, N. C. Santos +5
Planetary studies demand precise and accurate stellar parameters as input to infer the planetary properties. Different methods often provide different results that could lead to bi…
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD41248: stellar activity, no planets?
N. C. Santos, A. Mortier, J. P. Faria +21
The search for planets orbiting metal-poor stars is of uttermost importance for our understanding of the planet formation models. However, no dedicated searches have been conducted…
