“…Taking into account these statements, the metric of the black holes surrounded by the quintessence can be obtained by adding the quintessence term − c r 3ωq +1 to the metric of the black holes [38]. The metric of the regular Bardeen black hole in quintessence field can be expressed as…”

“…Recently, the quasinormal modes of the regular Bardeen black hole were investigated for gravitational perturbation [33], scalar perturbation [34][35][36], and Dirac perturbation [37]. Ghaderi and Malakolkalami [38] investigated the effects of quintessence on the thermodynamics of the black hole. In this paper, quasinormal modes of gravitational perturbation are investigated for the regular Bardeen black hole surrounded by quintessence.…”

In this paper, Quasinormal modes of gravitational perturbation are investigated for the regular Bardeen black hole surrounded by quintessence. Considering the metric of the Bardeen spacetime surrounded by quintessence, we derived the perturbation equation for gravitational perturbation using Regge-Wheeler gauge. The third order WentzelKramers-Brillouin (WKB) approximation method is used to evaluate quasinormal frequencies. Explicitly, the behaviors of the black hole potential and quasinormal modes were plotted. The results show that, due to the presence of quintessence, the gravitational perturbation around the black hole damps more slowly and oscillates more slowly.

“…This solution is a generalization of the Kiselev solution [53] to the charged case and its interesting properties are studied in [60][61][62][63]. Then, the generalized Kiselev solution is a subclass of our general dynamical solution (22) in the stationary limit.…”

In the present work, we generalize our previous work (Heydarzade and Darabi in arXiv:1710.04485, 2018 on the surrounded Vaidya solution by cosmological fields to the case of Bonnor-Vaidya charged solution. In this regard, we construct a solution for the classical description of the evaporating-accreting charged Bonnor-Vaidya black holes in the generic dynamical backgrounds. We address some interesting features of these solutions and classify them according to their behaviors under imposing the positive energy condition. Also, we analyze the timelike geodesics associated with the obtained solutions and show that some new correction terms arise in comparison to the case of standard Schwarzschild black hole. Then, we explore all these features for each of the cosmological backgrounds of dust, radiation, quintessence and cosmological constant-like fields in more detail.

In the present work, we study the general surrounded Vaidya solution by the various cosmological fields and its nature describing the possibility of the formation of naked singularities or black holes. Motivated by the fact that real astrophysical black holes as non-stationary and nonisolated objects are living in non-empty backgrounds, we focus on the black hole subclasses of this general solution describing a dynamical evaporating-accreting black holes in the dynamical cosmological backgrounds of dust, radiation, quintessence, cosmological constant-like and phantom fields, the so called "surrounded Vaidya black hole". Then, we analyze the timelike geodesics associated with the obtained surrounded black holes and we find that some new correction terms arise relative to the case of Schwarzschild black hole. Also, we address some of the subclasses of the obtained surrounded black hole solution for both dynamical and stationary limits. Moreover, we classify the obtained solutions according to their behaviors under imposing the positive energy condition and discuss how this condition imposes some severe and important restrictions on the black hole and its background field dynamics.
