Aims. This article aims to measure the age of stars with planets (SWP) through stellar tracks and isochrones computed with the PAdova and TRieste Stellar Evolutionary Code (PARSEC). Methods. We developed algorithms based on two different techniques for determining the ages of field stars: isochrone placement and Bayesian estimation. Their application to a synthetic sample of coeval stars shows the intrinsic limits of each method. For instance, the Bayesian computation of the modal age tends to… Expand
The ages of exoplanet hosts and field stars
The thesis aims at homogeneously determining the ages of exoplanet hosts and generic field stars using stellar evolutionary tracks and isochrones computed with the PAdova & TRieste StellarExpand
Benchmark ages for the Gaia benchmark stars
In the era of large-scale surveys of stars in the MilkyWay, stellar ages are crucial for studying the evolution of the Galaxy.But determining ages of field stars is notoriously difficult; therefore,Expand
Age consistency between exoplanet hosts and field stars
Transiting planets around stars are discovered mostly through photometric surveys. Unlike radial velocity surveys, photometric surveys do not tend to target slow rotators, inactive or metal-richExpand
Evolved stars and the origin of abundance trends in planet hosts
Tentative evidence that the properties of evolved stars with planets may be different from what we know for MS hosts has been recently reported. We aim to test whether evolved stars with planets showExpand
Radii, masses, and ages of 18 bright stars using interferometry and new estimations of exoplanetary parameters
Accurate stellar parameters are needed in numerous domains of astrophysics. The position of stars on the H-R diagram is an important indication of their structure and evolution, and it helps improveExpand
The masses of retired A stars with asteroseismology:: Kepler and K2 observations of exoplanet hosts
We investigate the masses of "retired A stars" using asteroseismic detections on seven low-luminosity red-giant and sub-giant stars observed by the NASA Kepler and K2 Missions. Our aim is to exploreExpand
MCMCI: A code to fully characterise an exoplanetary system
Useful information can be retrieved by analysing the transit light curve of a planet-hosting star or induced radial velocity oscillations. However, inferring the physical parameters of the planet,Expand
Hα-activity and ages for stars in the SARG survey
Stellar activity influences radial velocity (RV) measurements and can also mimic the presence of orbiting planets. As part of the search for planets around the components of wide binaries performedExpand
The EBLM project – VIII. First results for M-dwarf mass, radius, and effective temperature measurements using CHEOPS light curves
The accuracy of theoreticalmass, radius and effective temperature values forM-dwarf stars is an active topic of debate. Differences between observed and theoretical values have raised the possibilityExpand
The Muscles Treasury Survey. I. Motivation and Overview
Ground- and space-based planet searches employing radial velocity techniques and transit photometry have detected thousands of planet-hosting stars in the Milky Way. With so many planets discovered,Expand


Discrepancies between isochrone fitting and gyrochronology for exoplanet host stars
Using a sample of 68 planet-hosting stars, I carry out a comparison of isochrone fitting and gyrochronology to investigate whether tidal interactions between the stars and their planets are leadingExpand
On the ages of exoplanet host stars
We obtained spectra, covering the CaII H and K region, for 49 exoplanet host (EH) stars, observable from the southern hemisphere. We measured the chromospheric activity index, RHK. We compiledExpand
Isochrone ages for field dwarfs: method and application to the age–metallicity relation
A new method is presented to compute age estimates from theoretical isochrones using temperature, luminosity and metallicity data for individual stars. Based on Bayesian probability theory, thisExpand
The Ages of Stars
The age of an individual star cannot be measured, only estimated through mostly model-dependent or empirical methods, and no single method works well for a broad range of stellar types or for a fullExpand
Improving Stellar and Planetary Parameters of Transiting Planet Systems: The Case of TrES-2
We report on a spectroscopic determination of the atmospheric parameters and chemical abundance of the parent star of the recently discovered transiting planet TrES-2. A detailed LTE analysis of aExpand
Basic physical parameters of a selected sample of evolved stars
We present the detailed spectroscopic analysis of 72 evolved stars, which were previously studied for accurate radial velocity variations. Using one Hyades giant and another well studied star as theExpand

Determination of stellar ages from isochrones: Bayesian estimation versus isochrone fitting
We present a new method, using Bayesian estimation, to determine stellar ages and their uncertainties from observational data and theoretical isochrones. The result for an individual star is obtainedExpand

We derive detailed theoretical models for 1074 nearby stars from the SPOCS (Spectroscopic Properties of Cool Stars) Catalog. The California and Carnegie Planet Search has obtained high-quality (RExpand
Indications for an influence of hot Jupiters on the rotation and activity of their host stars
Context. The magnetic activity of planet-hosting stars is an important factor to estimate the atmospheric stability of close-in exoplanets and the age of their host stars. It has long been speculatedExpand
