From solar-like to antisolar differential rotation in cool stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract Stellar differential rotation can be separated into two main regimes: solar-like when the equator rotates faster than the poles and antisolar when the polar regions rotate faster than the equator. We investigate the transition between these two regimes with 3D numerical simulations of rotating spherical shells.

Solar activity and differential rotation [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractThe coronal sidereal rotation rate as a function of latitude for each year, extending from 1992 to 2001 for soft X-ray images and from 1998 - 2005 for radio images are obtained. The present analysis reveals that the equatorial rotation rate of the corona is comparable to the photosphere and the chromosphere, However, at the higher latitudes ...

On Differential Rotation and Overshooting in Solar-like Stars [PDF]
The Astrophysical Journal, 2017 Abstract We seek to characterize how the change of global rotation rate influences the overall dynamics and large-scale flows arising in the convective envelopes of stars covering stellar spectral types from early G to late K. We do so through numerical simulations with the ASH code, where we consider stellar convective envelopes coupled

The solar differential rotation in the 18th century [PDF]
Astronomy & Astrophysics, 2012 The sunspot drawings of Johann Staudacher of 1749--1799 were used to determine the solar differential rotation in that period. These drawings of the full disk lack any indication of their orientation. We used a Bayesian estimator to obtain the position angles of the drawings, the corresponding heliographic spot positions, a time offset between the ...
