Ultrahigh Energy Neutrals from Extreme Magnetic Flares
Abstract
It is shown that bulk acceleration during reconnection of extremely strong magnetic fields near compact objects can accelerate ions to Lorentz factors of 102 σ3/5 under general conditions, where σ, the magnetic energy per current-carrying proton rest energy, can approach 1015. For magnetar-type fields, neutrons and neutrinos can be generated at potentially detectable levels via hadron polarization. Ultrahigh energy photons can also be emitted and escorted from the high field region by Poynting flux.
