Machine Learning for Reconstruction of Polarity Inversion Lines from Solar Filaments
Solar filaments are well-known tracers of polarity inversion lines that separate two opposite magnetic polarities on the solar photosphere. Because...

Magnetic Orientation in Birds and Other Animals
The use of the geomagnetic field for compass orientation is widespread among animals, with two types of magnetic compass mechanisms described: an...

Gnevyshev Gap in the Large-Scale Magnetic Field
The phenomenon of the Gnevyshev gap was first identified in the solar-corona irradiance data (green line). Later, it was studied in the sunspot,...

Magnetic Helicity with Solar Dynamo
The research on solar dynamo can be said to begin with the discovery of the 11-year cycle from the statistical observation of sunspot activity and to...

Magnetic Evolution of an Active Region Producing Successive Flares and Confined Eruptions
We analyze the magnetic evolution of solar active region (AR) NOAA 11476 that, between May 9 and 10, 2012, produced a series of surge-type eruptions...

Behaviour of 27-Day and 13.5-Day Periodicities in Galactic Cosmic Particles as Observed by Spacecraft and Neutron Monitors During Different Solar Polarity Cycles
An analysis has been made of the behaviour of the 27-day and 13.5-day periodicities in proton, C, and O galactic-cosmic-ray (GCR) particles at...

Undetected Minority-Polarity Flux as the Missing Link in Coronal Heating
During the last few decades, the most widely favored models for coronal heating have involved the in situ dissipation of energy, with footpoint...

Effect of Solvent Polarity on the Physical Properties and Antibacterial and Antifungal Activity of TiO2 and Ag/TiO2 Nanoparticles
The study aimed to investigate the influence of solvent polarity (ethanol and distilled water (DW)) on modifying the shape, structure, size, and...

Peculiarities of the Interstellar Dust Distribution in the Heliosphere Induced by the Time-Dependent Magnetic Field
Interstellar dust enters the heliosphere due to the relative motion of the Sun and the Local Interstellar Cloud, which contains the Sun. The dynamics...

Polar Photospheric Magnetic Field Evolution and Global Flux Transport
The Sun’s polar magnetic fields are of paramount importance in structuring the heliosphere and in seeding the activity cycle, but they are difficult...
-
Ripples and Rush-to-the-Poles in the Photospheric Magnetic Field
The distribution of magnetic fields of positive and negative polarities over the surface of the Sun was studied on the basis of synoptic maps...

The Sun and Its Restless Magnetic Field
The permanently changing magnetic field of the Sun is the ultimate driver of the various effects refered to as space weather. This chapter gives an...
-
Stellar Magnetic Fields
Stellar magnetic fields are directly detected or inferred across the whole Hertzsprung--Russell Diagram. Attention in this chapter is concentrated on...

Basic Structures of Solar Magnetic Fields
Observations of the solar magnetic field enable humans to successfully extend the knowledge of electromagnetic physical processes beyond Earth. The...
-
Helical Magnetic Field and Solar Cycles
In recent years, a large number of observational data based on the solar vector magnetic field have been obtained. They have been used to investigate...
