Angular Energy Distribution of Collapsar-Jets
Collapsars are fast-spinning, massive stars, whose core collapse liberates an energy, that can be channeled in the form of ultrarelativistic jets. These jets transport the energy from the collapsed core to large distances, where it is dissipated in the form of long-duration gamma-ray bursts. In this paper we study the dynamics of ultrarelativistic jets produced in collapsars. Also we extrapolat...
متن کاملWave Modes in Collapsar Jets
Collapsars may be a source for the “long” Gamma Ray Bursts (GRBs) in the BATSE catalog. Collapsars may radiate gamma rays anisotropically by beamed jet emission close to the observer’s line of sight. These jets must penetrate the radiation-dominated medium of their collapsar progenitor and break through its atmosphere in order to produce a GRB. We present a study of previously published, axisym...
متن کاملCollapsar Jets , Bubbles and Fe Lines
According to collapsar models, gamma ray bursts are caused by relativistic jets that expel energy along the rotation axis of a collapsing stellar core. We discuss how the structure and time-dependence of such jets depends on the properties of the stellar envelope and the central engine. It takes a few seconds for the jet to bore its way through the core of the star; most of the energy output du...
متن کاملAngular Structure of Qcd Jets
We derive the angular correlation functions between an arbitary number of partons inside a quark or gluon jet emerging from a high energy hard collision. As an application results for the correlation in the relative angle between two partons as well as the multiplicity moments of any order for partons in a sidewise angular region are calculated. At asymptotic energies the distributions of resca...
متن کاملA possible observational evidence for θ angular distribution of opening half-angle of GRB jets
We propose a method to estimate the pseudo jet opening half-angle of GRBs using the spectral peak energy (Ep)–peak luminosity relation (so called Yonetoku relation) as well as the Ep–collimation-corrected γ-ray energy relation (so called Ghirlanda relation). For bursts with known jet break times and redshifts, we compared the pseudo jet opening half-angle with the standard one and found that th...
