Different magnetic features between solar polar and equatorial magnetic fields
Solar polar and equatorial photospheric (FeIλ5324.19 Å line) magnetic fields have been observed using the vector video magnetograph at Huairou Solar Observing Station of Beijing Astronomical Observatory. It is found from our observations that the magnetic fields of small-scale magnetic features near the solar poles are stronger than in quiet equatorial regions near the limb, and that strong pol...
متن کاملInteractions Between Solar Neutrinos and Solar Magnetic Fields
We attempt to correlate all of the available solar-neutrino capture-rate data with the strong magnetic fields these neutrinos encounter in the solar interior along their Earth-bound path. We approximate these fields using the (photospheric, magnetograph-measured) surface magnetic flux from central latitude bands, time delayed to proxy the solar interior. Our strongest evidence for anticorrelati...
متن کاملSelf-Consistent hot spot tracing particles by kinetic simulations: With the emphasis on Cusp particle entry
One of the most important advantages of particle simulation as compared to fluid simulation is the capacity for working with and tracing particles. In particle simulations, the test particle method is usually used to get some idea of the behavior of plasma or other substances. In this method, first, a small number of particles are injected into the frame of static electromagnetic fields. Then, ...
متن کاملTwisted Solar Active Region Magnetic Fields as Drivers of Space Weather: Observational and Theoretical Investigations
The properties and dynamics of magnetic fields on the Sun’s photosphere and outer layers – notably those within solar active regions – govern the eruptive activity of the Sun. These photospheric magnetic fields also act as the evolving lower boundary of the Sun-Earth coupled system. Quantifying the physical attributes of these magnetic fields and exploring the mechanisms underlying their influe...
متن کاملParticle-in-cell simulations of the solar wind interaction with lunar crustal magnetic anomalies: Magnetic cusp regions
[1] As the solar wind is incident upon the lunar surface, it will occasionally encounter lunar crustal remanent magnetic fields. These magnetic fields are small-scale, highly non-dipolar, have strengths up to hundreds of nanotesla, and typically interact with the solar wind in a kinetic fashion. Simulations, theoretical analyses, and spacecraft observations have shown that crustal fields can re...
متن کاملEfficient solar anti-neutrino production in random magnetic fields
We have shown that the electron anti-neutrino appearance in the framework of the spin flavor conversion mechanism is much more efficient in the case of neutrino propagation through random than regular magnetic field. This result leads to much stronger limits on the product of the neutrino transition magnetic moment and the solar magnetic field based on the recent KamLAND data. We argue that the...
