The magnetic fields of intermediate-mass T Tauri stars : I. Magnetic detections and fundamental stellar parameters
Florent Villebrun, Evelyne Alecian, Gaitee Hussain +13
Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated. Aims. We want to bring observational constr…
Impacts of radiative accelerations on solar-like oscillating main-sequence stars
M. Deal, G. Alecian, Y. Lebreton +5
Chemical element transport processes are among the crucial physical processes needed for precise stellar modelling. Atomic diffusion by gravitational settling nowadays is usually t…
Gaia Data Release 2: first stellar parameters from Apsis
Rene Andrae, Morgan Fouesneau, Orlagh Creevey +13
The second Gaia data release (Gaia-DR2) contains, beyond the astrometry, three-band photometry for 1.38 billion sources. We have used these three broad bands to infer stellar effec…
Gaia Data Release 2: Variable stars in the colour-absolute magnitude diagram
Gaia Collaboration, L. Eyer, L. Rimoldini +14
The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G ~ 21 mag. We showcase stellar variability across the Galactic colour-absolute mag…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
Gaia Collaboration, F. van Leeuwen, A. Vallenari +589
Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry,…
SpaceInn hare-and-hounds exercise: Estimation of stellar properties using space-based asteroseismic data
D. R. Reese, W. J. Chaplin, G. R. Davies +15
Context: Detailed oscillation spectra comprising individual frequencies for numerous solar-type stars and red giants are or will become available. These data can lead to a precise…
Masses of the components of SB2 binaries observed with Gaia. III. Accurate SB2 orbits for 10 binaries and masses of HIP 87895
Flavien Kiefer, Jean-Louis Halbwachs, Frédéric Arenou +9
In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the SOPHIE spectrograph at the Haute--Provence Observato…
Masses of the components of SB2 binaries observed with Gaia. II. Masses derived from PIONIER interferometric observations for Gaia validation
J. -L. Halbwachs, H. M. J. Boffin, J. -B. Le Bouquin +15
In anticipation of the Gaia astrometric mission, a sample of spectroscopic binaries is being observed since 2010 with the Sophie spectrograph at the Haute--Provence Observatory. Ou…
Seismic analysis of HD43587Aa, a solar-like oscillator in a multiple system
P. Boumier, O. Benomar, F. Baudin +26
Context. The object HD 43587Aa is a G0V star observed during the 145-day LRa03 run of the COnvection, ROtation and planetary Transits space mission (CoRoT), for which complementary…
Deterministically Driven Avalanche Models of Solar Flares
Antoine Strugarek, Paul Charbonneau, Richard Joseph +1
We develop and discuss the properties of a new class of lattice-based avalanche models of solar flares. These models are readily amenable to a relatively unambiguous physical inter…
Properties of 42 Solar-type Kepler Targets from the Asteroseismic Modeling Portal
T. S. Metcalfe, O. L. Creevey, G. Dogan +39
Recently the number of main-sequence and subgiant stars exhibiting solar-like oscillations that are resolved into individual mode frequencies has increased dramatically. While only…
Impact of asteroseismology on improving stellar ages determination
Yveline Lebreton
High precision photometry as performed by the CoRoT and Kepler satellites on-board instruments has allowed to detect stellar oscillations over the whole HR diagram. Oscillation fre…
Stellar ages and convective cores in field main-sequence stars: first asteroseismic application to two Kepler targets
V. Silva Aguirre, S. Basu, I. M. Brandão +21
Using asteroseismic data and stellar evolution models we make the first detection of a convective core in a Kepler field main-sequence star, putting a stringent constraint on the t…
Seismic diagnostics for transport of angular momentum in stars 1. Rotational splittings from the PMS to the RGB
J. P. Marques, M. J. Goupil, Y. Lebreton +12
Rotational splittings are currently measured for several main sequence stars and a large number of red giants with the space mission Kepler. This will provide stringent constraints…
Seismic signature of envelope penetrative convection: the CoRoT star HD 52265
Yveline Lebreton, MarieJo Goupil
Aims: We aim at characterizing the inward transition from convective to radiative energy transport at the base of the convective envelope of the solar-like oscillator HD 52265 rece…
Escape of stars from gravitational clusters in the Chandrasekhar model
Mohammed Lemou, Pierre-Henri Chavanis
We study the evaporation of stars from globular clusters using the simplified Chandrasekhar model. This is an analytically tractable model giving reasonable agreement with more sop…
