Constraining the Dynamo Layers in Jupiter and Saturn with Observations and Scaling Laws

The Astrophysical Journal
The dipole-dominated magnetic fields of Jupiter and Saturn provide evidence for active dynamos operating within their deep interiors, yet the depth of the convecting dynamo layers remains poorly constrained.

An Optimized Screen Reduces the Number of GA Transporters and Provides Insights Into Nitrate Transporter 1/Peptide Transporter Family Substrate Determinants

Frontiers in Plant Science, 2019
Based on recent in vitro data, a relatively large number of the plant nitrate transporter 1/peptide transporter family (NPF) proteins have been suggested to function as gibberellic acid (GA) transporters.

Quasi-biennial oscillations and Rieger-type periodicities in a Babcock–Leighton solar dynamo

Astronomy & Astrophysics
Context. The Sun’s magnetic field exhibits the 11 year solar cycle as well as shorter periodicities, popularly known as the quasi-biennial oscillations (QBOs) and Rieger-type periods.

Testing the reliability of magnetic field strength measurements for M dwarfs

Astronomy & Astrophysics
Context. M dwarfs are known to host strong magnetic fields, which can be measured through several complementary techniques. However, the impact of key methodological choices on Zeeman broadening diagnostics has not been systematically quantified.

Geomagnetism, volcanoes, global climate change, and predictability. A progress report

Annals of Geophysics, 1994
A model is investigated, by which the encounters of the solar system with dense interstellar clouds ought to trigger either geomagnetic field reversals or excursions, that produce extra electric currents within the Earth dynamo, that cause extra Joule's ...

Coexisting Tayler instability-driven dynamos in radiative zones: New dynamo solution and its impacts on stellar physics

Astronomy & Astrophysics
Recent asteroseismic observations constitute a great challenge for rotating stellar evolution models, which predict overly fast internal rotation rates when only hydrodynamic processes are included.
