Assessment of PLATO Science Performance
Juan Cabrera, Heike Rauer, Reza Samadi +121
The PLATO mission is scheduled for launch early 2027. In this paper we present an overview of the performance drivers for the mission at the time where all flight models of the cam…
Latitudinal differential rotation in the solar analogues 16 Cyg A and B
M. Bazot, O. Benomar, J. Christensen-Dalsgaard +5
Asteroseismology has undergone a profound transformation as a scientific field following the CoRoT and Kepler space missions. The latter is now yielding the first measurements of l…
Starspot rotation rates vs. activity cycle phase: Butterfly diagrams of Kepler stars are unlike the Sun's
M. B. Nielsen, L. Gizon, R. H. Cameron +1
During the solar magnetic activity cycle the emergence latitudes of sunspots change, leading to the well-known butterfly diagram. This phenomenon is poorly understood for other sta…
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…
Limits on radial differential rotation in Sun-like stars from parametric fits to oscillation power spectra
M. B. Nielsen, H. Schunker, L. Gizon +2
Rotational shear in Sun-like stars is thought to be an important ingredient in models of stellar dynamos. Thanks to helioseismology, rotation in the Sun is characterized well, but…
Constraining differential rotation of Sun-like stars from asteroseismic and starspot rotation periods
M. B. Nielsen, H. Schunker, L. Gizon +1
In previous work we identified six Sun-like stars observed by Kepler with exceptionally clear asteroseismic signatures of rotation. Here, we show that five of these stars exhibit s…
Rotational splitting as a function of mode frequency for six Sun-like stars
M. B. Nielsen, L. Gizon, H. Schunker +1
Asteroseismology offers the prospect of constraining differential rotation in Sun-like stars. Here we have identified six high signal-to-noise main-sequence Sun-like stars in the K…
Kepler White Paper: Asteroseismology of Solar-Like Oscillators in a 2-Wheel Mission
W. J Chaplin, H. Kjeldsen, J. Christensen-Dalsgaard +53
We comment on the potential for continuing asteroseismology of solar-type and red-giant stars in a 2-wheel Kepler Mission. Our main conclusion is that by targeting stars in the ecl…
