Flow Regimes in Hot Jupiter Atmospheres: Insights from Anelastic Models
W. Dietrich, J. Wicht
Hot Jupiters are Jupiter-sized exoplanets with close-in orbits, characterized by extreme day-night temperature contrasts due to synchronous rotation. These planets offer unique obs…
Reconstructing wind fields from gravitational data on gas giants: An investigation of mathematical methods
Tim-Jonas Peter, Volker Michel, Franz-Theo Suttmeier +1
The atmospheric structure of gas giants, especially those of Jupiter and Saturn, has been an object of scientific studies for a long time. The measurement of the gravitational fiel…
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…
Westward hotspot offset explained by subcritical dynamo action in an ultra-hot Jupiter atmosphere
Vincent G. A. Böning, Wieland Dietrich, Johannes Wicht
Hot Jupiters are tidally-locked Jupiter-sized planets close to their host star. They have equilibrium temperatures above about 1000 K. Photometric observations find that the hotspo…
