Modeling of differential rotation in rapidly rotating solar-type stars
Modeling differential rotation rapidly rotating solar-type stars
2011/10/9
We investigate differential rotation in rapidly rotating solar-type stars by means of an axisymmetric mean field model that was previously applied to the sun. This allows us to calculate the latitudin...
Analysis of 3D MHD Instability of Antisolar Latitudinal Differential Rotation in F, G and K stars
Analysis Instability Latitudinal Differential Rotation
2011/10/8
Motivated by observations that only a very few stars have been found to have antisolar differential rotation, much weaker in amplitude than that of the Sun, we analyze the stability of antisolar and s...
Rotation and differential rotation in rapidly rotating field stars
differential rotation rapidly rotating field stars
2011/1/13
We continue our studies on stellar latitudinal differential rotation. The presented work is a sequel of the work of Reiners et al. who studied the spectral line broadening profile of hundreds of stars...
Differential rotation on the young solar analogue V889 Herculis
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging. The 10 FOCES spectra collecte...
Differential Rotation and Magnetism in Simulations of Fully Convective Stars
Solar and Stellar Astrophysics (astro-ph.SR) Fluid Dynamics (physics.flu-dyn)

Stars of sufficiently low mass are convective throughout their interiors, and so do not possess an internal boundary layer akin to the solar tachocline.
