Selection and characterisation of the M-dwarf targets in the PLATO Input Catalogue
L. Prisinzano, M. Montalto, G. Piotto +33
The ESA's PLAnetary Transits and Oscillations of Stars (PLATO) mission aims to detect planets orbiting around dwarfs and subgiant stars with spectral type F5 or later, including M-…
Glitches in solar-like oscillating F-type stars: Possible contribution of non-linear terms
M. Deal, M. -J. Goupil, J. Philidet +3
The glitch signatures in for F-type stars (higher amplitude and period of the oscillatory component) are very different from those of G-type stars. The aim of this work i…
Measuring stellar surface rotation and activity with the PLATO mission -- I. Strategy and application to simulated light curves
S. N. Breton, A. F Lanza, S. Messina +20
The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands of main sequence so…
Entropy-calibrated stellar modeling: Testing and improving the use of prescriptions for entropy of adiabatic convection
L. Manchon, M. Deal, M. -J. Goupil +7
The modeling of convection is a long standing problem in stellar physics. Up-to-now, all ad hoc models rely on a free parameter alpha (among others) which has no real physical just…
Predicted asteroseismic detection yield for solar-like oscillating stars with PLATO
M. J. Goupil, C. Catala, R. Samadi +26
We determine the expected yield of detections of solar-like oscillations for the PLATO ESA mission. We used a formulation from the literature to calculate the probability of detect…
Locked differential rotation in core-helium burning red giants
B. Mosser, G. Dreau, C. Pincon +5
Oscillation modes of a mixed character are able to probe the inner region of evolved low-mass stars and offer access to a range of information, in particular, the mean core rotatio…
Probing the mid-layer structure of red giants I. Mixed-mode coupling factor as a seismic diagnosis
C. Pinçon, M. -J. Goupil, K. Belkacem
The space-borne missions CoRoT and Kepler have already brought stringent constraints on the internal structure of low-mass evolved stars, a large part of which results from the det…
Asymmetry of line profiles of stellar oscillations measured by Kepler for ensembles of solar-like oscillators: impact on mode frequencies and dependence on effective temperature
O. Benomar, Mjo. Goupil, K. Belkacem +7
Oscillation properties are usually measured by fitting symmetric Lorentzian profiles to the power spectra of Sun-like stars. However the line profiles of solar oscillations have be…
Dipole modes with depressed amplitudes in red giants are mixed modes
B. Mosser, K. Belkacem, C. Pincon +6
Seismic observations have shown that a number of evolved stars exhibit low-amplitude dipole modes, which are referred to as depressed modes. Recently, these low amplitudes have bee…
Period-luminosity relations in evolved red giants explained by solar-like oscillations
B. Mosser, W. A. Dziembowski, K. Belkacem +8
Solar-like oscillations in red giants have been investigated with CoRoT and Kepler, while pulsations in more evolved M giants have been studied with ground-based microlensing surve…
Seismic diagnostics for transport of angular momentum in stars 2. Interpreting observed rotational splittings of slowly-rotating red giant stars
M. J. Goupil, B. Mosser, J. P. Marques +4
Asteroseismology with the space-borne missions CoRoT and Kepler provides a powerful mean of testing the modeling of transport processes in stars. Rotational splittings are currentl…
Modelling a high-mass red giant observed by CoRoT
F. Baudin, C. Barban, M. J. Goupil +15
The G6 giant HR\,2582 (HD\,50890) was observed by CoRoT for approximately 55 days. Mode frequencies are extracted from the observed Fourier spectrum of the light curve. Numerical s…
Red-giant seismic properties analyzed with CoRoT
B. Mosser, K. Belkacem, M. J. Goupil +10
The CoRoT 5-month long observation runs give us the opportunity to analyze a large variety of red-giant stars and to derive fundamental stellar parameters from their asteroseismic…
Solar-like oscillations in low-luminosity red giants: first results from Kepler
T. R. Bedding, D. Huber, D. Stello +47
We have measured solar-like oscillations in red giants using time-series photometry from the first 34 days of science operations of the Kepler Mission. The light curves, obtained w…
Mode excitation by turbulent convection in rotating stars. I. Effect of uniform rotation
K. Belkacem, S. Mathis, M. J. Goupil +1
We focus on the influence of the Coriolis acceleration on the stochastic excitation of oscillation modes in convective regions of rotating stars. Our aim is to estimate the asymmet…
Asteroseismology and interferometry of the red giant star epsilon Oph
A. Mazumdar, A. Merand, P. Demarque +16
The GIII red giant star epsilon Oph has been found to exhibit several modes of oscillation by the MOST mission. We interpret the observed frequencies of oscillation in terms of the…
