A common law for the differential rotation of planets and stars
Vincent G. A. Böning, Johannes Wicht
All planets and stars rotate. All gas planets in our solar system, the Sun, and many stars show a pattern of east- or westward mean flows. This phenomenon is known as differential…
Transition to turbulence in the wide-gap spherical Couette system
Ankit Barik, Santiago A. Triana, Michael Hoff +1
The spherical Couette system consists of two differentially rotating concentric spheres with a fluid filled in between. We study a regime where the outer sphere is rotating rapidly…
Linking Zonal Winds and Gravity II: explaining the equatorially antisymmetric gravity moments of Jupiter
Wieland Dietrich, Paula Wulff, Johannes Wicht +1
The recent gravity field measurements of Jupiter (Juno) and Saturn (Cassini) confirm the existence of deep zonal flows reaching to a depth of 5\% and 15\% of the respective radius.…
Stable stratification promotes multiple zonal jets in a turbulent Jovian dynamo model
T. Gastine, J. Wicht
The ongoing NASA's Juno mission puts new constraints on the internal dynamics of Jupiter. Data gathered by its onboard magnetometer reveal a dipole-dominated surface magnetic field…
Explaining Jupiter's magnetic field and equatorial jet dynamics
T. Gastine, J. Wicht, L. Duarte +2
Spacecraft data reveal a very Earth-like Jovian magnetic field. This is surprising since numerical simulations have shown that the vastly different interiors of terrestrial and gas…
Zonal flow scaling in rapidly-rotating compressible convection
T. Gastine, M. Heimpel, J. Wicht
The surface winds of Jupiter and Saturn are primarily zonal. Each planet exhibits strong prograde equatorial flow flanked by multiple alternating zonal winds at higher latitudes. T…
From solar-like to anti-solar differential rotation in cool stars
T. Gastine, R. K. Yadav, J. Morin +2
Stellar differential rotation can be separated into two main regimes: solar-like when the equator rotates faster than the poles and anti-solar when the polar regions rotate faster…
What controls the large-scale magnetic fields of M dwarfs?
T. Gastine, J. Morin, L. Duarte +3
Observations of active M dwarfs show a broad variety of large-scale magnetic fields encompassing dipole-dominated and multipolar geometries. We detail the analogy between some anel…
What controls the magnetic geometry of M dwarfs?
T. Gastine, J. Morin, L. Duarte +3
Context: observations of rapidly rotating M dwarfs show a broad variety of large-scale magnetic fields encompassing dipole-dominated and multipolar geometries. In dynamo models, th…
Zonal flow regimes in rotating anelastic spherical shells: an application to giant planets
T. Gastine, J. Wicht, J. M. Aurnou
The surface zonal winds observed in the giant planets form a complex jet pattern with alternating prograde and retrograde direction. While the main equatorial band is prograde on t…
Dipolar versus multipolar dynamos: the influence of the background density stratification
T. Gastine, L. Duarte, J. Wicht
Context: dynamo action in giant planets and rapidly rotating stars leads to a broad variety of magnetic field geometries including small scale multipolar and large scale dipole-dom…
Effects of compressibility on driving zonal flow in gas giants
T. Gastine, J. Wicht
The banded structures observed on the surfaces of the gas giants are associated with strong zonal winds alternating in direction with latitude. We use three-dimensional numerical s…
