Genetic Algorithm for Inferring Model Parameters for Flux Transport Dynamo Simulation
The Astrophysical JournalThe Sun exhibits an 11 yr cyclic variation, maintained by dynamo action in the solar interior. Mean-field flux transport dynamo models have successfully reproduced most of the features observed in solar cycles, while the model includes many free ...

Probes of the solar interior [PDF]
, 1998 The interior of the sun is not directly accessible to observations. Nonetheless, it is possible to infer the physical conditions prevailing in the solar interior with the help of theory of stellar structure and the powerful observational input provided ...

Seismic Probes of Solar Interior Magnetic Structure
Physical Review Letters, 2012 Sunspots are prominent manifestations of solar magnetoconvection and imaging their subsurface structure is an outstanding problem of wide physical importance. Travel times of seismic waves that propagate through these structures are typically used as inputs to inversions.

Biermann Battery Magnetic Flux Generation in the Deep Solar Interior
The Astrophysical JournalTime-series analyses of helioseismic data and solar neutrino data have indicated the potential existence of a second tachocline at the core–radiative zone interface, which may in turn require consideration of an additional source of magnetic flux ...

Differential Rotation in the Solar Interior [PDF]
International Astronomical Union Colloquium, 1970 One of the big problems in stellar rotation which has been the object of much debate recently concerns the magnitude of the angular velocity in the central regions of the sun. It is a good example of our general ignorance of the distribution of angular momentum in the interiors of stars. There is good reason, of course, for this ignorance.

Optimisation of solar sail interplanetary heteroclinic connections [PDF]
, 2014 This paper investigates time-optimal solar sail trajectories between displaced Libration Point Orbits (LPOs) of different circular restricted three-body systems.

Magnetic Fields in the Solar Convection Zone
Living Reviews in Solar Physics, 2004 Recent studies of the dynamic evolution of magnetic flux tubes in the solar convection zone are reviewed with focus on emerging flux tubes responsible for the formation of solar active regions. The current prevailing picture is that active regions on the
