Magnetorotational instability in a solar near-surface mean-field dynamo
Axel Brandenburg, Gustav Larsson, Fabio Del Sordo +1
We address the question whether the magnetorotational instability (MRI) can operate in the near-surface shear layer (NSSL) of the Sun and how it affects the interaction with the dy…
Variable, circularly polarized radio emission from the Young Stellar Object [BHB2007]-1: another ingredient of a unique system
Simranpreet Kaur, Josep M. Girart, Daniele Viganò +7
The young stellar object [BHB2007]-1 has been extensively studied in the past at radio, millimeter, and infrared wavelengths. It shows a gap in the disk and previous observations c…
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…
