The solar differential rotation in the 18th century [PDF]

open access: yesAstronomy & 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.

On Differential Rotation and Overshooting in Solar-like Stars [PDF]

open access: yesThe Astrophysical Journal, 2017
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.

Generation of Solar-like Differential Rotation [PDF]

open access: yesThe Astrophysical Journal, 2022
We analyze the simulation result shown in Hotta & Kusano (2021) in which the solar-like differential rotation is reproduced. The Sun is rotating differentially with the fast equator and the slow pole.

Transition from anti-solar to solar-like differential rotation: Dependence on Prandtl number [PDF]

open access: yesAstronomy & Astrophysics, 2022
(abridged) Context: Late-type stars such as the Sun rotate differentially due to the interaction of turbulent convection and rotation. Aims: The aim of the study is to investigate the effects of the thermal Prandtl number on the transition from anti ...

Solar activity and differential rotation [PDF]

open access: yesProceedings 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 ...

Differential rotation of the solar corona: A new data-adaptive multiwavelength approach [PDF]

open access: yesAstronomy & Astrophysics, 2020
Context. The characterization of the differential rotation of the extended corona is still lacking conclusive results about the actual rotation rate profiles, and it is also expected to vary along the solar cycle.

Latitudinal differential rotation in the solar analogues 16 Cygni A and B [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. Asteroseismology has undergone a profound transformation as a scientific field following the CoRoT and Kepler space missions. The latter is now yielding the first measurements of latitudinal differential rotation obtained directly from ...

Dependence of Stellar Differential Rotation on Effective Temperature and Rotation: An Analysis from Starspot Transit Mapping [PDF]

open access: yesThe Astrophysical Journal, 2023
Stellar rotation is crucial for studying stellar evolution, since it provides information about age, angular momentum transfer, and magnetic fields of stars.

Solar-cycle-related variation of solar differential rotation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
Solar-cycle-related variation of differential rotation is investigated through analysing the rotation rates of magnetic fields, distributed along latitudes and varying with time at the time interval of 1976 August to 2008 April.

DYNAMO EFFECTS NEAR THE TRANSITION FROM SOLAR TO ANTI-SOLAR DIFFERENTIAL ROTATION [PDF]

open access: yes, 2015
Numerical MHD simulations play an increasingly important role for understanding the mechanisms of stellar magnetism. We present simulations of convection and dynamos in density-stratified rotating spherical fluid shells.
