Strongest constraint in $f (R) = R + α R^{2}$ gravity: stellar stability

Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis

In the metric approach of $f (R)$ theories of gravity, the fourth-order field equations are often recast as effective Einstein equations in the presence of standard matter and a cur…

Massive scalar wave packet emission by a charged Black Hole and Cosmic Censorship Conjecture violation

Rodrigo L. Fernandez, Ribamar R. R. Reis, Sergio E. Jorás

We study the tunneling probability of a massive ( $m_{w}$ ) uncharged scalar packet out from a near-extremal, static charged black hole (with mass $M$ and charge $Q ≲ M$ ). We sho…
