Radiation from Relativistic Strongly Magnetized Outflows

Usov, Vladimir V.

Original · EN

Relativistic strongly magnetized winds outflowing from fast-rotating compact objects like millisecond pulsars with surface magnetic fields of 10¹⁵-10¹⁶ G are plausible sources of cosmological γ-ray bursts. In such winds, there are at least three regions where extremely powerful X-ray and γ-ray emission may be generated. The first radiating region is the wind photosphere that is at a distance of 10⁹ cm from the compact object. The second radiating region is at a distance of 10¹³-10¹⁴ cm. In this region, the striped component of the wind field is transformed into large-amplitude electromagnetic waves. The third radiating region is at a distance of 10¹⁶-10¹⁷ cm, where deceleration of the wind due to its interaction with an ambient medium becomes important. Radiation from all these regions is considered.
