Even a weak magnetic field crossing a current sheet can drive its evolution, broaden the reconnecting layer, and strongly suppress tearing instability, challenging a key assumption of classical reconnection theory.

Magnetic reconnection is a fundamental process in astrophysical plasmas, allowing

A new study investigates how accreted matter forms magnetic mountains on white dwarfs, deforming their magnetic fields and potentially burying much of their original magnetic flux.

White dwarfs are compact stellar remnants with extremely high densities

Extending classical tearing theory to gyrotropic MHD, this study shows how pressure anisotropy influences instability growth rates and magnetic reconnection in weakly collisional plasmas.

A new LAT@EACH-USP preprint develops a linear theory for tearing instability in gyrotropic MHD, showing how pressure anisotropy modifies magnetic reconnection onset in weakly collisional plasmas.

3D MHD simulations reveal how turbulence and complex magnetic fields accelerate cosmic rays in colliding-wind binaries, highlighting processes beyond classical shock acceleration.

A new MNRAS paper by LAT@EACH-USP researchers investigates how turbulence and magnetic-field complexity help accelerate particles in massive stellar binaries.
