The lost sunspot cycle: New support from Be10 measurements
C. Karoff, F. Inceoglu, M. F. Knudsen +2
It has been suggested that the deficit in the number of spots on the surface of the Sun between 1790 and 1830, known as the Dalton minimum, contained an extra cycle that was not id…
Kepler-432: a red giant interacting with one of its two long period giant planets
Samuel N. Quinn, Timothy R. White, David W. Latham +28
We report the discovery of Kepler-432b, a giant planet () transiting an evolved star $(M_\star =…
Magnetic activity, differential rotation and dynamo action in the pulsating F9IV star KIC 5955122
A. Bonanno, H. -E. Fröhlich, C. Karoff +3
We present photometric spot modeling of the nearly four-year long light-curve of the Kepler target KIC 5955122 in terms of persisting dark circular surface features. With a Bayesia…
Asteroseismic inference on the spin-orbit misalignment and stellar parameters of HAT-P-7
Mikkel N. Lund, Mia Lundkvist, Victor Silva Aguirre +12
The measurement of obliquities in star-planet systems is of great importance for the understanding of planet system formation and evolution. The bright and well studied HAT-P-7 sys…
Kepler-93b: A Terrestrial World Measured to within 120 km, and a Test Case for a New Spitzer Observing Mode
Sarah Ballard, William J. Chaplin, David Charbonneau +22
We present the characterization of the Kepler-93 exoplanetary system, based on three years of photometry gathered by the Kepler spacecraft. The duration and cadence of the Kepler o…
Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
R. A. Garcia, T. Ceillier, D. Salabert +16
Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied for thousands of stars…
