عنوان	Thermodynamics and Null Geodesics of a Bardeen Black Hole Surrounded by Quintessence
نوع پژوهش	مقاله چاپ‌شده در مجلات علمی
کلیدواژه‌ها	Bardeen Black Hole, Quintessence, Thermodynamics
چکیده	We study the thermodynamics of a Bardeen black hole surrounded by quintessence, and we analyze null geodesics and all kinds of orbits corresponding to the energy levels for this black hole. Using the thermodynamical laws of the black holes, we derive the thermodynamic properties and investigate the mass, temperature and heat capacity as functions of entropy. We also study the circular orbits, calculate the deflection angle of photons and compare our results with those obtained for the Schwarzschild black hole surrounded by quintessence matter.
