In this region, which the scientists call the «merging point,» the presence of cold, dense plasma slows magnetic reconnection, blunting the sun's effects on Earth.
They plan to examine data from other instruments on MAVEN to see if escaping particles map to the same regions where they see reconnected magnetic fields to confirm that reconnection is contributing to Martian atmospheric loss and determine how significant it is.
Numerical simulations performed by the GRAPES - 3 collaboration on this event indicate that the Earth's magnetic shield temporarily cracked due to the occurrence of magnetic reconnection, allowing the lower energy galactic cosmic ray particles to enter our atmosphere.
Magnetic reconnection, in addition to pushing around clouds of plasma, converts some magnetic energy into heat, which has an effect on just how much energy is left over to move the particles througMagnetic reconnection, in addition to pushing around clouds of plasma, converts some magnetic energy into heat, which has an effect on just how much energy is left over to move the particles througmagnetic energy into heat, which has an effect on just how much energy is left over to move the particles through space.
To see whether these are generated by the same process as happens on the sun — the breaking and reconnection of magnetic fields (pictured above)-- astronomers studied light from 100,000 stars using China's Guo Shouiing Telescope.
«One idea is that the process of magnetic reconnection on the night side of Earth causes a build - up of «trapped» hot plasma in the higher latitude lobes.»
«We found that the energetic plasma signatures occur on high - latitude magnetic field lines that have been «closed» by the process of magnetic reconnection, which then causes the plasma to become relatively hot,» says Dr Fear.
On the other hand, Cassini plasma and magnetic field observations revealed signatures of reconnection at Saturn's magnetopause (McAndrews et al. 2008).
Here is a story on Phys.org about a new finding involving plasmoid instabilities and magnetic reconnection.
Alternatively to solar wind driven reconnection, the viscous interaction of the solar wind with the planetary magnetosphere, which involves magnetic reconnection on a small scale (Delamere & Bagenal 2013), influences Saturn's magnetopause dynamics.
He conducted magnetic reconnection experiments while earning his doctorate and then moved to the National Spherical Torus Experiment - Upgrade (NSTX - U), joining the team that conducted the first 10 weeks of operation on the upgraded facility.
The coronal magnetic reconnection hypothesis can explain the observations via the notion that superflares and solar flares share the same origin and that the two activity distributions therefore are within similar range, but that superflares mainly take place on stars with activity levels larger than the Sun.
When the solar wind carries CMEs and other powerful bursts of radiation into a planet's magnetic field, it can cause the magnetic field on the back side to press together, a process known as magnetic reconnection.
The selected doctoral candidate will use a state - of - the - art fully - kinetic and massively parallel particle - in - cell code, running on European network High - Performance Supercomputers, to simulate the electromagnetic radiation caused by magnetic reconnection.
The successful applicant will work with Prof. Dr. Jörg Büchner and Dr. Patricio Muñoz on kinetic simulations of electron acceleration by magnetic reconnection in stellar atmospheres to be verified by observed solar type - III radio bursts.
They discovered that the lobe, an area of the magnetosphere which is usually filled with cold, unenergetic, plasma, does in some cases fill up with hot plasma when magnetic reconnection occurs on the night side of the Earth, thus closing the field lines and trapping the plasma within.
