Solar rotation
This paper reviews current understanding of the internal rotation of the Sun. We summarise the outcome of the latest helioseismic measurements of the angular velocity profile, and review existing dynamical models of rotation in the convection zone and in the radiative zone beneath. Finally, we discuss preliminary results along a new line of investigation.
متن کاملBis(μ2-N-methyl-N-phenyldithiocarbamato)-κ3 S,S′:S;κ3 S:S,S′-bis[(N-methyl-N-phenyldithiocarbamato-κ2 S,S′)cadmium]: crystal structure and Hirshfeld surface analysis
The title compound, [Cd2(C8H8NS2)4], is a centrosymmetric dimer with both chelating and μ2-tridentate di-thio-carbamate ligands. The resulting S5 donor set defines a CdII coordination geometry inter-mediate between square-pyramidal and trigonal-bipyramidal, but tending towards the former. The packing features C-H⋯S and C-H⋯π inter-actions, which generate a three-dimensional network. The influen...
متن کاملAnnual variation in near-Earth solar wind speed: Evidence for persistent north-south asymmetry related to solar magnetic polarity
We study the annual variation in solar wind speed at Earth’s orbit and in geomagnetic activity since mid1960’s. The two parameters depict a very similar annual variation during the whole period. Annual variation has maximum amplitude around sunspot minima. The phase of annual variation reverses soon after solar maxima, following the Sun’s polarity reversal and indicating a new type of 22-year p...
متن کاملthe solar cycle signal on the Earth ’ s surface ? ” by
This paper studies the 11-year solar cycle signal in Earth’s surface using historical datasets and the surface evidence is further supported by the zonal mean vertical profile using ERA-Interim and previously archived model simulations. The authors present many surface and zonal mean quantities that are composited between high and low solar years. Although majority of the results presented here...
متن کاملSolar Interior Rotation and its Variation
This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts to determine the solar core rotation from oblateness and proceeding through the development of helioseismology to the detailed modern picture of the internal rotation deduced from continuous helioseism...
