Dynamics of Particles Around a Schwarzschild-like Black Hole in the Presence of Quintessence and Magnetic Field

Understand

We investigate the dynamics of a neutral and a charged particle around a static and spherically symmetric black hole in the presence of quintessence matter and external magnetic field.

• We explore the conditions under which the particle moving around the black hole could escape to infinity after colliding with another particle.
• The innermost stable circular orbit (ISCO) for the particles are studied in detail.
• Mainly the dependence of ISCO on dark energy and on the presence of external magnetic field in the vicinity of black hole is discussed.
