Computer scientist tracks satellites with automated observatory built from off-the-shelf technology
1. In-Situ Solar Wind & Coronal Magnetic Field Observations
Heliospheric spacecraft flying through the inner solar system have obtained unprecedented high-cadence magnetohydrodynamic measurements of the solar wind. Instruments detected sharp, localized reversals in the radial magnetic field—known as magnetic switchbacks—accompanied by sudden spikes in solar wind proton speed and plasma density.
2. Interchange Magnetic Reconnection Mechanics
Theoretical astrophysicists attribute these switchbacks to interchange reconnection occurring near the solar transition region and corona. When open magnetic field lines dragging into interplanetary space reconnect with closed magnetic loops anchored in the photosphere, magnetic tension releases an explosive Alfvénic pulse. This wave propagates outward, temporarily bending the local magnetic field back toward the Sun.
3. Solving the Coronal Heating Paradox
Understanding the genesis of magnetic switchbacks is central to resolving one of astrophysics’ greatest enigmas: why the solar corona sits at over 1,000,000 Kelvin while the solar surface beneath is only 5,800 Kelvin. Energy carried by reconnecting switchbacks dissipates into thermal plasma turbulence, driving coronal heating and accelerating the fast solar wind across the heliosphere.
