Chintzoglou and his colleagues developed a model that identified locations on the Sun where the magnetic field was especially compressed, since rapid releases of energy — such as those they observed when the filament collapsed — are more likely to occur
where magnetic field lines are strongly distorted.
These form in areas
where magnetic field lines converge, producing cooler regions of «only» about 3,000 — 4,000 degrees Celsius (by contrast with their surroundings of 5,000 degrees Celsius or higher).
Not exact matches
By combining observations from the ground and in space, the team observed a plume of low - energy plasma particles that essentially hitches a ride along
magnetic field lines — streaming from Earth's lower atmosphere up to the point, tens of thousands of kilometers above the surface,
where the planet's
magnetic field connects with that of the sun.
So the north
magnetic pole is
where the earth's
magnetic field lines pull toward the planet, acting like the south pole of a bar magnet.
The
magnetic field lines originate in the Earth's core and emerge near the poles,
where their angle of dip — or inclination — relative to Earth's surface is almost 90 degrees.
Given the corona is not expected to change much before the eclipse, scientists at the NSO used current observations to create a coronal
magnetic model that shows
where they expect to see
field lines concentrated during the eclipse.
This channel is especially good at showing coronal loops - the arcs extending off of the Sun
where plasma moves along
magnetic field lines.
They emerge
where dense bundles of
magnetic field lines from the sun's interior break through the surface.
The increased equatorward wind at middle latitudes tends to push the ionosphere higher up along
magnetic field lines,
where the loss rate is lower.
