Topological Features in the Emerging Solar Magnetic Flux

Proceedings of the International Astronomical Union, 2023
AbstractThe formation of highly structured, spatially localized complex structures during solar flux emergence facilitates adaptation of topological methods, extending the research of emerging macroscopic MHD fluxes into knots, links and braids. Combining mathematical considerations, remote images and in situ satellite observations at solar vicinity ...

Solar magnetic flux tube emergence diagram

Astronomical & Astrophysical Transactions, 1994
Abstract It is emphasized that photospheric downdrafts represent the main feature common to both quit and active regions of the solar atmosphere. The results of the magnetic field transport velocity calculations are used to specify the convection zone magnetic structure. The concept of combined interface and convection dynamo is suggested.

Peculiarities of the magnetic flux emerging in the equatorial solar zone

Geomagnetism and Aeronomy, 2016
The magnetic flux longitudinal distribution in the equatorial solar zone has been studied. The magnetic synoptic maps of the Wilcox Solar Observatory (WSO) during Carrington rotations (CRs) 2052–2068 in 2007 and early 2008 have been analyzed. The longitudinal distributions of the area of the zones where the photospheric magnetic field locally enhanced ...

In Search of Emerging Magnetic Flux underneath the Solar Surface with Acoustic Imaging

The Astrophysical Journal, 1999
With the method of acoustic imaging in helioseismology, we study an emerging flux region, NOAA 7978, using data taken with instruments of the Taiwan Oscillation Network (TON) and the Michelson Doppler Imager (MDI). Phase-shift maps of NOAA 7978 focusing at different depths are constructed, which show the evolution of emerging magnetic flux.

Resistive magnetic flux emergence and formation of solar active regions

EAS Publications Series, 2012
Magnetic flux emergence as the mechanism leading to the formation of magnetized structures in the solar atmosphere plays a key role in the dynamic of the Sun. Observed as a whole, emerging flux regions show clear signs of twisted structure, bearing the magnetic free energy necessary to power active events. The high resolution observations of the recent

Emergence of magnetic flux at the solar surface and the origin of active regions

Astronomy Reports, 2009
The evolution of photospheric velocities from the first minutes after the emergence of fresh magnetic flux and the formation of the first pores in active region NOAA 10488 is studied with a time resolution of 1 min and spatial resolution of 4″. The emerging magnetic flux of a major active region is initially a bundle of magnetic-flux loops.

Non-equilibrium of Magnetic Flux Tubes emerging into the Solar Corona

Solar Physics, 1997
A lack of equilibrium of twisted magnetic flux tubes emerging from the photosphere into the corona is considered. Assuming mass and flux conservation in the tube and an isothermal tube that is in thermal equilibrium with the surrounding plasma, it is shown that a sufficently rapid temperature increase through the transition zone may lead to the loss of

Plasma motions in the solar loop of emerging magnetic flux

Kinematics and Physics of Celestial Bodies, 2014
The results of analyzing variations in the line-of-sight (LOS) velocities in the solar loop at photospheric and chromospheric levels in the region of emerging magnetic flux for the evolving active region NOAA 11024 are reported. The analysis combines the data of multiwave spectropolarimetric observations that were carried out on July 4, 2009, (Tenerife,
