Asteroseismic modelling of main-sequence solar-like stars and Kepler exoplanet host stars with the FICO procedure I. Catalogue of fundamental stellar properties
Jérôme Bétrisey, Daniel R. Reese, Camilla Pezzotti +2
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward…
Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars
Sylvain N. Breton, Camilla Pezzotti, Stéphane Mathis +5
After the recent detection of solar equatorial Rossby waves, a renewed interest has been brought to the study of gravito-inertial waves propagating in the convective envelope of so…
Eating planets makes you younger: The magnetic dynamo rejuvenation of GJ 504 by planetary engulfment
S. Bellotti, C. Pezzotti, G. Buldgen +3
With the discovery of a few thousand exoplanets, questions have been raised regarding star-planet interactions and whether the presence of a companion may affect stellar properties…
On the contradictory case of the binary system HD 81809 hosting two pulsating solar-like stars observed by TESS
Maria Pia Di Mauro, Camilla Pezzotti, Nuno Moedas +8
We present a new comprehensive study of HD81809, a nearby binary system of two solar-like stars showing high-amplitude X-ray emission and a well-defined 8-year solar-like magnetic…
The stellar activity-rotation-age relationship under the lens of asteroseismology
C. Pezzotti, J. Bétrisey, G. Buldgen +6
In low-mass stars, the connection between magnetic activity, rotation period, and age provides key insights into the functioning of dynamos. Fully understanding the activity-rotati…
Asteroseismic modelling of Kepler Legacy stars including lithium depletion
G. Buldgen, J. Bétrisey, C. Pezzotti +2
Context. The Kepler Legacy sample is, to this day, the sample of solar-like oscillators with the most exquisite asteroseismic data. In this work, we carry out a detailed modelling…
Constraints on the properties of macroscopic transport in the Sun from combined lithium and beryllium depletion
G. Buldgen, A. Noels, A. M. Amarsi +5
Context. The Sun is a privileged laboratory of stellar evolution, thanks to the quality and complementary nature of available constraints. Using these observations, we are able to…
Thorough characterisation of the 16 Cygni system. Part II. Seismic inversions of the internal structure
G. Buldgen, M. Farnir, P. Eggenberger +5
The advent of space-based photometry observations provided high-quality asteroseismic data for a large number of stars. These observations enabled the adaptation of advanced techni…
Coralie radial velocity search for companions around evolved stars (CASCADES) II. Seismic masses for three red giants orbited by long-period massive planets
G. Buldgen, G. Ottoni, C. Pezzotti +10
The advent of asteroseismology as the golden path to precisely characterize single stars naturally led to synergies with the field of exoplanetology. Today, the precise determinati…
Thorough characterisation of the 16 Cygni system Part I: Forward seismic modelling with WhoSGlAd
M. Farnir, M. -A. Dupret, G. Buldgen +5
Context: Being part of the brightest solar-like stars, and close solar analogues, the 16 Cygni system is of great interest to the scientific community and may provide insight into…
From the Sun to solar-like stars: how does the solar modelling problem affect our studies of solar-like oscillators?
G. Buldgen, C. Pezzotti, M. Farnir +2
Since the first observations of solar oscillations in 1962, helioseismology has probably been one of the most successful fields of astrophysics. Besides the improvement of observat…
Revisiting Kepler-444 Part I. Seismic modelling and inversions of stellar structure
G. Buldgen, M. Farnir, C. Pezzotti +10
Context. The CoRoT and Kepler missions have paved the way for synergies between exoplanetology and asteroseismology. The use of seismic data helps providing stringent constraints o…
AGB stars and the plate archives heritage
Roberto Nesci, Silvia Gaudenzi, Corinne Rossi +3
We report on the characterization of a number of AGB candidate stars identified with objective-prism plates of the Byurakan Observatory. Digitized photographic sky survey plates an…
