Inflated hot Jupiters: Inferring average atmospheric velocity via Ohmic models coupled with internal dynamo evolution
Daniele Viganò, Soumya Sengupta, Clàudia Soriano-Guerrero +4
The inflated radii observed in hundreds of hot Jupiters (HJ) represent a long-standing open issue. In this study, we quantitatively investigate this phenomenon within the framework…
Rossby number regime, convection suppression, and dynamo-generated magnetism in inflated hot Jupiters
Albert Elias-López, Matteo Cantiello, Daniele Viganò +3
Hot Jupiters (HJs) are commonly thought to host the strongest dynamo-generated magnetic fields among exoplanets, up to one order of magnitude larger than Jupiter. Thus, they have o…
Vorticity and magnetic dynamo from subsonic expansion waves II: Dependence on magnetic Prandtl number, forcing scale, cooling time
Albert Elias-López, Fabio del Sordo, Daniele Viganò
The amplification of astrophysical magnetic fields takes place via dynamo instability in turbulent environments. The presence of vorticity is crucial for the dynamo to happen. Howe…
The role of Ohmic dissipation of internal currents on Hot Jupiter radii
Taner Akgün, Clàudia Soriano-Guerrero, Albert Elias-López +3
The inflated radii observed in hundreds of Hot Jupiters represent a long-standing open issue. The observed correlation between radii and irradiation strength, and the occasional ex…
Vorticity and magnetic dynamo from subsonic expansion waves
Albert Elias-López, Fabio Del Sordo, Daniele Viganò
This work concentrates on the effect of an irrotational forcing on a magnetized flow in the presence of rotation, baroclinicity, shear, or a combination of them. By including magne…
