Dust collapse in asymptotic safety: a path to regular black holes
Alfio Bonanno, Daniele Malafarina, Antonio Panassiti
Regular black hole spacetimes are obtained from an effective Lagrangian for Quantum Einstein Gravity. The interior matter is modeled as a dust fluid, which interacts with the geome…
Magnetic activity evolution of solar-like stars: I. S_ph-Age relation derived from Kepler observations
Savita Mathur, Zachary R. Claytor, Angela R. G. Santos +9
The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archaeology. While ages are usually computed from stellar evolut…
On the ultraviolet behavior of conformally reduced quadratic gravity
Alfio Maurizio Bonanno, Maria Conti, Sergio Luigi Cacciatori
We study the conformally reduced theory of gravity and we show that the theory is asymptotically safe with an ultraviolet critical manifold of dimension three. In particula…
Stability properties of Regular Black Holes
Alfio Bonanno, Frank Saueressig
Black holes encountered in general relativity are characterized by spacetime singularities hidden within an event horizon. These singularities provide a key motivation to go beyond…
On the origin of the dichotomy of stellar activity cycles
Alfio Bonanno, Enrico Corsaro
The presence of possible correlations between stellar rotation rate and the frequency of the activity cycle is still much debated. We implement a new Bayesian…
Regular evaporating black holes with stable cores
Alfio Bonanno, Amir-Pouyan Khosravi, Frank Saueressig
A feature shared by many regular black hole spacetimes is the occurrence of a Cauchy horizon. It is then commonly believed that this renders the geometry unstable against perturbat…
