Activity cycles in RS CVn type stars
C. I. Martínez, P. J. D. Mauas, A. P. Buccino
We compile a list of 121 RS CVn type stars from the bibliography in southern hemisphere, to search for activity cycles, covering a large range of luminosities and rotation periods.…
Overspinning naked singularities in AdS spacetime
Matías Briceño, Cristián Martínez, Jorge Zanelli
The BTZ black hole belongs to a family of locally three-dimensional anti-de Sitter (AdS) spacetimes labeled by their mass and angular momentum . The case $M \ell \geq |J…
Quantum-corrected black holes and naked singularities in (2+1)-dimensions
Marc Casals, Alessandro Fabbri, Cristián Martínez +1
We analytically investigate the pertubative effects of a quantum conformally-coupled scalar field on rotating (2+1)-dimensional black holes and naked singularities. In both cases w…
Geodesic Structure of Naked Singularities in AdS Spacetime
Cristián Martínez, Nicolás Parra, Nicolás Valdés +1
We present a complete study of the geodesics around naked singularities in AdS, the three-dimensional anti-de Sitter spacetime. These stationary spacetimes, characterized by tw…
Quantum Backreaction on Three-Dimensional Black Holes and Naked Singularities
Marc Casals, Alessandro Fabbri, Cristián Martínez +1
We analytically investigate backreaction by a quantum scalar field on two rotating Bañados-Teitelboim-Zanelli (BTZ) geometries: that of a black hole and that of a naked singularity…
Quantum dress for a naked singularity
Marc Casals, Alessandro Fabbri, Cristián Martínez +1
We investigate semiclassical backreaction on a conical naked singularity space-time with a negative cosmological constant in (2+1)-dimensions. In particular, we calculate the renor…
