标题： Magnetically charged black-bounce solution via nonlinear electrodynamics in a k-essence theory

摘要： 在本工作中，我们获得并分析了磁荷黑洞反弹在k-本质理论中的新一类解析解，在(3+1)维中球对称，并与非线性电动力学(NED)耦合。 我们考虑两种度规模型，Simpson-Visser和Bardeen，用于k-本质配置n = 1/3和n = 1/5。 我们以解析方式获得支持这些度规所需的标量场、场势和NED拉格朗日量。 我们分析了这些量以及由于标量场和NED导致的能量条件的行为。 显示英文摘要

摘要： In the present work, we obtain and analyze a new class of analytical solutions of magnetically charged black bounces in k-essence theory, spherically symmetric in (3+1)-dimensions, coupled to nonlinear electrodynamics (NED). We consider two metric models, Simpson-Visser and Bardeen, for the k-essence configurations n = 1/3 and n = 1/5. We obtain in an analytical way which scalar field, field potential, and Lagrangian NED are necessary to support the metrics. We analyze the behavior of these quantities and the energy conditions due to the scalar field and the NED.
