Exact Solutions of the Gardner Equation and their Applications to the Different Physical Plasmas
Daghan, D.; Donmez, O. (SPRINGER, 2016)Traveling wave solution of the Gardner equation is studied analytically by using the two dependent (G (')/G,1/G)-expansion and (1/G ('))-expansion methods and direct integration. The exact solutions of the Gardner equations ... -
Investigating the effect of integration constants and various plasma parameters on the dynamics of the soliton in different physical plasmas
Daghan, D.; Donmez, O. (AMER INST PHYSICS, 2015)The nonlinear dynamics and propagation of ion acoustic waves in a relativistic and ideal plasmas, which have the pressure variation of electrons and ions and degenerate electrons, are investigated using the analytic solution ... -
NUMERICAL SIMULATION OF ASTROPHYSICAL JETS: INTERACTION WITH SURROUNDING MEDIUM
Donmez, O.; Aktas, A.; Ilter, U. (SPRINGER/PLENUM PUBLISHERS, 2017)Propagation of astrophysical jets inside an ambient medium transports a large amount of energy to surrounding materials as a consequence of interactions. These interactions have a crucial effect on the evolution and dynamics ... -
On the development of quasi-periodic oscillations in Bondi-Hoyle accretion flows
Donmez, O.; Zanotti, O.; Rezzolla, L. (WILEY-BLACKWELL, 2011)The numerical investigation of the Bondi-Hoyle accretion on to a moving black hole has a long history, both in Newtonian and in general-relativistic physics. By performing new two-dimensional and general-relativistic ... -
On the development of the Papaloizou-Pringle instability of the black hole-torus systems and quasi-periodic oscillations
Donmez, O. (OXFORD UNIV PRESS, 2014)We present the numerical study of dynamical instability of a pressure-supported relativistic torus, rotating around the black hole with a constant specific angular momentum on a fixed space-time background, in case of ... -
Relativistic simulation of flip-flop instabilities of Bondi-Hoyle accretion and quasi-periodic oscillations
Donmez, O. (OXFORD UNIV PRESS, 2012)It is known from recent numerical calculations that BondiHoyle accretion creates a shock cone behind compact objects. This type of accretion leads to instabilities, which can explain certain astrophysical phenomena. In ...
