Stability of the spacetime of a magnetized compact object

Autor: Ribeiro, Eveling C., Formigari, L., Ribeiro Jr., Marcos R., Abdalla, Elcio, Cuadros-Melgar, Bertha, Molina, C., de Queiroz, Amilcar R., Saa, Alberto

We investigate the stability of scalar perturbations around a magnetized stationary compact object in General Relativity. The considered object is one of the simplest exact solutions of Einstein electrovacuum equations corresponding to a spheroidal b

Black-hole evaporation for cosmological observers

Autor: Campos, T. L., Molina, C., Lima, J. A. S.

In the present work, evaporation of a black hole immersed in a de Sitter environment is considered. Vaidya-de Sitter spacetime is used to model the process in a scenario of accelerated expansion of the Universe. The role of observers is highlighted i

Generating Kerr-anti-de Sitter thermodynamics

Autor: Campos, T. L., Baldiotti, M. C., Molina, C.

Publikováno v: Physical Review D 110, 024049 (2024)

In the present work we study the construction of different thermodynamic descriptions for the Kerr-anti-de Sitter (KadS) black holes. The early versions of the KadS thermodynamics are briefly discussed, highlighting some of its strong points and shor

Síntesis y caracterización de nuevos materiales: arcillas modificadas con pilares mixtos

Autor: Sun Kou, María del Rosario, Molina, C. B., Valverde Palomino, J. L., Cañizares Cañizares, P.

Publikováno v: Revista de Química. 12(1):5-18

En este trabajo, se han preparado nuevos materiales microporosos con pilares mixtos de Al-Fe, Al-Cr, y Al-Ce, a partir de dos arcillas bentoníticas: una comercial (bentonita Fischer) y otra peruana (Bentonita B). La estructura de estos materiales pi

Weyl conjecture and thermal radiation of finite systems

Autor: Baldiotti, M. C., Jaraba, M. A., Santos, L. F., Molina, C.

Publikováno v: J. Phys. A: Math. Theor. 56, 015002 (2023)

In this work, corrections for the Weyl law and Weyl conjecture in d dimensions are obtained and effects related to the polarization and area term are analyzed. The derived formalism is applied on the quasithermodynamics of the electromagnetic field i
