Constraining the outer boundary condition for the Babcock-Leighton dynamo models
Astronomy & AstrophysicsContext. The evolution of the Sun’s large-scale surface magnetic field is well captured by surface flux transport models, which can therefore provide a natural constraint on the outer boundary condition (BC) of Babcock–Leighton (BL) dynamo models.

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields
Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract The Martian ionosphere hosts complex current systems driven both by solar wind interactions and neutral wind dynamo processes. While the global patterns of these current systems have been statistically examined, their detailed structures and orientations remain poorly constrained.

SIMULATION STUDY OF HEMISPHERIC PHASE-ASYMMETRY IN THE SOLAR CYCLE [PDF]
, 2017 Observations of the Sun suggest that solar activities systematically create north–south hemispheric asymmetries. For instance, the hemisphere in which sunspot activity is more active tends to switch after the early half of each solar cycle.

Can stochastic resonance explain the amplification of planetary tidal forcing?
, 2019 Repeated Grand Minima revealed by proxies of solar activity suggest that the Sun alternates between two stable states, a quiescent and an active one. If the intrinsic noise of the solar dynamo allows for a frequent switching between these stable states ...

Magnetic Fields in the Solar Convection Zone
Living Reviews in Solar Physics, 2009 Active regions on the solar surface are generally thought to originate from a strong toroidal magnetic field generated by a deep seated solar dynamo mechanism operating at the base of the solar convection zone.

Predicting Geomagnetic Activity in the Ascending and Declining Phases of the Solar Cycle
Space Weather, Volume 24, Issue 8, August 2026.Abstract Most predictions of space climate, that is, the long‐term behavior of the solar‐terrestrial environment, have focused on forecasting the 11‐year sunspot cycle. Geomagnetic activity, on the other hand, has mainly been predicted in shorter, space weather timescales of up to days to weeks.

The solar tachocline: a self-consistent model of magnetic confinement [PDF]
, 2011 In this dissertation we consider the dynamics of the solar interior, with particular focus on angular momentum balance and magnetic field confinement within the tachocline. In Part I we review current knowledge of the Sun's rotation.

Quasi-biennial oscillations and Rieger-type periodicities in a Babcock–Leighton solar dynamo
Astronomy & AstrophysicsContext. 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.
