The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addressesExpand
Spin down of the core rotation in red giants
Context. The space mission Kepler provides us with long and uninterrupted photometric time series of red giants. We are now able to probe the rotational behaviour in their deep interiors using theExpand
The connection between stellar granulation and oscillation as seen by the Kepler mission
Context. The long and almost continuous observations by Kepler show clear evidence of a granulation background signal in a large sample of stars, which is interpreted as the surface manifestation ofExpand
Testing Scaling Relations for Solar-like Oscillations from the Main Sequence to Red Giants Using Kepler Data
We have analyzed solar-like oscillations in ~1700 stars observed by the Kepler Mission, spanning from the main sequence to the red clump. Using evolutionary models, we test asteroseismic scalingExpand
Probing the core structure and evolution of red giants using gravity-dominated mixed modes observed with Kepler
Context. There are now more than 22 months of long-cadence data available for thousands of red giants observed with the Kepler space mission. Consequently, we are able to clearly resolve fine detailsExpand
Kepler observations of the variability in B-type stars
The analysis of the light curves of 48 B-type stars observed by Kepler is presented. Among these are 15 pulsating stars, all of which show low frequencies, characteristic of slowly pulsating B (SPB)Expand
The Kepler characterization of the variability among A- and F-type stars I. General overview
Context. The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. Aims. We present a first general characterization of theExpand
The Rotation of the Deep Solar Layers
From the analysis of low-order GOLF+MDI sectoral modes (l ≤ 3, 6 ≤ n ≤ 15, |m| = l) and LOWL data (l > 3), we derive the radial rotation profile by assuming no latitudinal dependence in the solarExpand
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 total size of theExpand
Magnetic activity of F stars observed by Kepler
Context. The study of stellar activity is important because it can provide new constraints for dynamo models when combined with surface rotation rates and the depth of the convection zone. We knowExpand
