Asteroseismic inversions for radial differential rotation of Sun-like stars: ensemble fits
Hannah Schunker, Jesper Schou, Warrick Ball +2
Radial differential rotation is an important parameter for stellar dynamo theory and for understanding angular momentum transport. We investigate the potential of using a large num…
Data compression for local correlation tracking of solar granulation
Björn Löptien, Aaron C. Birch, Tom L. Duvall +2
Context. Several upcoming and proposed space missions, such as Solar Orbiter, will be limited in telemetry and thus require data compression. Aims. We test the impact of data compr…
Rotation, differential rotation, and gyrochronology of active Kepler stars
Timo Reinhold, Laurent Gizon
The high-precision photometry from the CoRoT and Kepler satellites has led to measurements of surface rotation periods for tens of thousands of stars. Our main goal is to derive ag…
Anisotropy of the solar network magnetic field around the average supergranule
J. Langfellner, L. Gizon, A. C. Birch
Supergranules in the quiet Sun are outlined by a web-like structure of enhanced magnetic field strength, the so-called magnetic network. We aim to map the magnetic network field ar…
Simulating acoustic waves in spotted stars
Emanuele Papini, Aaron C. Birch, Laurent Gizon +1
Acoustic modes of oscillation are affected by stellar activity, however it is unclear how starspots contribute to these changes. Here we investigate the nonmagnetic effects of star…
Spatially resolved vertical vorticity in solar supergranulation using helioseismology and local correlation tracking
J. Langfellner, L. Gizon, A. C. Birch
Flow vorticity is a fundamental property of turbulent convection in rotating systems. Solar supergranules exhibit a preferred sense of rotation, which depends on the hemisphere. Th…
