Spectral and timing properties of a dissipative GRB photosphere
Dimitrios Giannios, Henk C. Spruit
We explore the observational appearance of the photosphere of an ultrarelativistic flow with internal dissipation of energy as predicted by the magnetic reconnection model. Previou…
Magnetostatic penumbra models with field-free gaps
G. B. Scharmer, H. C. Spruit
We present numerical 2D magnetostatic models for sunspot penumbrae consisting of radially aligned field-free gaps in a potential magnetic field, as proposed by Spruit and Scharmer…
Magnetic instability in a differentially rotating star
H. C. Spruit
Instabilities in magnetic fields wound up by differential rotation as reviewed in Spruit (1999) are discussed with some detail and new developments added. In stellar models which i…
The role of kink instability in Poynting-flux dominated jets
Dimitrios Giannios, Henk C. Spruit
The role of kink instability in magnetically driven jets is explored through numerical one-dimensional steady relativistic MHD calculations. The instability is shown to have enough…
