Formation of relativistic jets by collapsing stars to black holes

Abstract

Formation of relativistic jets in the magnetosphere of collapsing stars is considered. These jets will be formed in the polar caps of magnetosphere of collapsing star, where the stellar magnetic field increases during the collapse and the charged particles are accelerated. The jets will generate non-thermal radiation. The analysis of dynamics and emission of particles in the stellar magnetosphere under collapse shows that collapsing stars can by powerful sources of relativistic jets.Comment: 8 pages, 3 figures, Accepted for publication in Adv.

Nonlinear structures: soliton, shocklike and explosive waves in quantum semiconductor plasma

“…On the other hand, superrelativistic positron beams are widely used in experimental particles and nuclear physics, mostly in electron and positron colliders [5,6]. However, it is very difficult to produce dense energetic positrons in laboratories [7,8], even though they may exist naturally in massive astrophysical objects like pulsars and black holes [9] and are likely to form gamma-ray bursts [10]. Later, the work has been extended [11,12] to study the ultracold Fermi dusty plasmas, in which the micro-and nanoscale devices are usually contaminated by the presence of highly charged dust impurities.…”

Gravitational Collapse of Stars and the Methods of Its Observations

“…As follows from the theoretical calculations, during the gravitational collapse of stars the gravitational and electromagnetic radiation will generate.

“…There are many models of the relativistic jets formation by the stellar collapse (Aloy et al, 2000;Beskin et al, 2008;Blandford and Payne 1982;Bucciantini et al, 2008;Couch et al, 2009;Fendt, 2009;Kato et al, 2004;Koide et al, 1998;Komissarov and Barkov, 2007;Kryvdyk, 2008;Kryvdyk, 2010;MacFadyen et al, 2001;Matsakos et al, 2008;Meliani et al, 2006;Mizuno, et al, 2004;Ono et al, 2009;Takiwaki et al, 2009;Uzdensky and MacFadyen, 2007;Zhang et al, 2003). Blandford and Znajek (1977) considered the model in which the relativistic particles acceleration and jets formation going on at great distances from the black hole in a magnetized accretional disk of a rotating black hole.…”

“…In author articles (Kryvdyk, 1998;Kryvdyk, 1999;Kryvdyk, 2009;Kryvdyk, 2010, Kryvdyk, 2014aKryvdyk, 2014b) was studied in detail the processes of charged particles acceleration in a magnetosphere of collapsing star, and the nonthermal radiation from these particles in a magnetic field was calculated. In these articles were calculated the synchrotron radiation flows from charged particles in a external magnetic field collapsing stars, that grows during the collapse and accelerate these particles by means of the betatron mechanism.…”
