No Sun-like dynamo on the active star Andromedae from starspot asymmetry
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +12
Sunspots are cool areas caused by strong surface magnetic fields inhibiting convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our…
Rotation--differential rotation relationships for late-type single and binary stars from Doppler imaging
Zs. Kővári, K. Oláh, L. Kriskovics +3
From our sample of spotted late-type stars showing surface differential rotation we find that the relationship between the rotation period and the surface shear coefficient $α=ΔΩ/Ω…
Antisolar differential rotation with surface lithium enrichment on the single K-giant V1192 Orionis
Zs. Kővári, K. G. Strassmeier, T. A. Carroll +7
Context: Stars with about 12 solar masses at the red giant branch (RGB) represent an intriguing period of stellar evolution, i.e. when the convective envelope interacts with the…
