Resonant cyclotron scattering modeling of the nonthermal spectra of these objects implies a plasma shell density up to four orders of magnitude higher than the Goldreich-Julian electron density of their less energetic versions. Local effects associated with them include Klein-Nishina pair creation, vacuum polarization birefringence, and Compton scattering suppression. (*) In 2008, fast optical flaring was confirmed in one of these objects, SWIFT J195509+261406. The first ring of matter around one was observed by the Spitzer Space Telescope, and absorption of their energy by these or by their coronae following crustal equilibrium collapse and fracturing is a proposed mechanism for the soft gamma repeater emission associated with them. FTP, name this type of neutron star proposed by Robert Duncan and Christopher Thompson, also responsible for X-ray Pulsar Emissions, and powered by the decay of magnetic fields on the order of 10 gigateslas.
