ACTIN: A tool to calculate stellar activity indices
J. Gomes da Silva, P. Figueira, N. C. Santos +1
Magnetic activity in the atmospheres of stars produces a number of spectroscopic signatures that are visible in the shape and strength of spectral lines. These signatures can be us…
SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
Activity induced variation in spin-orbit angles as derived from Rossiter-McLaughlin measurements
M. Oshagh, A. H. M. J. Triaud, A. Burdanov +17
One of the most powerful methods used to estimate sky-projected spin-orbit angles of exoplanetary systems is through a spectroscopic transit observation known as the Rossiter-McLau…
Planets around evolved intermediate-mass stars in open clusters II. Are there really planets around IC4651No9122, NGC2423No3 and NGC4349No127?
E. Delgado Mena, C. Lovis, N. C. Santos +10
(shorter version)The aim of this work is to search for planets around intermediate-mass stars in open clusters by using RV data obtained with HARPS from an extensive survey with mo…
The TROY project: II. Multi-technique constraints on exotrojans in nine planetary systems
J. Lillo-Box, A. Leleu, H. Parviainen +10
Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the Solar System. Although planet-size co-orbitals do not exists in our planetary system, dyn…
kima: Exoplanet detection in radial velocities
J. P. Faria, N. C. Santos, P. Figueira +1
The radial-velocity (RV) method is one of the most successful in the detection of exoplanets, but is hindered by the intrinsic RV variations of the star, which can easily mimic or…
Chemical abundances of neutron capture elements in exoplanet-hosting stars
E. Delgado Mena, V. Zh. Adibekyan, P. Figueira +7
To understand the formation and composition of planetary systems it is important to study their host stars composition since both are formed in the same stellar nebula. In this wor…
Quantifying the Bayesian Evidence for a Planet in Radial Velocity Data
Benjamin E. Nelson, Eric B. Ford, Johannes Buchner +5
We present results from a data challenge posed to the radial velocity (RV) community: namely, to quantify the Bayesian "evidence" for n={0,1,2,3} planets in a set of synthetically…
An Earth-sized exoplanet with a Mercury-like composition
A. Santerne, B. Brugger, D. J. Armstrong +43
The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
Recovering the colour-dependent albedo of exoplanets with high-resolution spectroscopy: from ESPRESSO to the ELT
J. H. C. Martins, P. Figueira, N. C. Santos +5
The characterization of planetary atmospheres is a daunting task, pushing current observing facilities to their limits. The next generation of high-resolution spectrographs mounted…
