Eclipsing time variations in close binaries produced by azimuthal dynamo waves

Felipe H. Navarrete, Dominik R. G. Schleicher, Petri J. Käpylä +1

The nature of eclipsing time variations (ETVs) in post-common-envelope binaries (PCEBs) is still unknown. Circumbinary planets routinely fail the test of time and the Applegate mec…

Shaping core dynamos in A-type stars: The role of dipolar fossil fields

J. P. Hidalgo, P. J. Käpylä, D. R. G Schleicher +2

Large-scale magnetic fields of Ap/Bp stars are stable over long timescales and have typically simple dipolar geometries, leading to the idea of a fossil origin. These stars are als…

Magnetohydrodynamic simulations of A-type stars: Long-term evolution of core dynamo cycles

J. P. Hidalgo, P. J. Käpylä, D. R. G Schleicher +2

Early-type stars have convective cores due to a steep temperature gradient produced by the CNO cycle. These cores can host dynamos, and the generated magnetic fields can be relevan…

Effects of the centrifugal force in stellar dynamo simulations

Felipe H. Navarrete, Petri J. Käpylä, Dominik R. G. Schleicher +1

The centrifugal force is often omitted from simulations of stellar convection either for numerical reasons or because it is assumed to be weak compared to the gravitational force.…

Origin of magnetism in early-type stars

J. P. Hidalgo, P. J. Käpylä, C. A. Ortiz-Rodríguez +3

According to our understanding of stellar evolution, early-type stars have radiative envelopes and convective cores due to a steep temperature gradient produced by the CNO cycle. S…

Simulations of fully convective M dwarfs: dynamo action with varying magnetic Prandtl numbers

Carolina A. Ortiz-Rodríguez, Dominik R. G. Schleicher, Petri J. Käpylä +1

M dwarfs are low-mass main-sequence stars, the most numerous type of stars in the solar neighbourhood, which are known to have significant magnetic activity. The aim of this work i…
