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…

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…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
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

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…

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
