Relativistic and Newtonian Proca Stars: A Tale of Two Limits
Alberto Diez-Tejedor, Carlos Herdeiro, Claudio Lazarte +4
We investigate a representative set of static solitonic solutions of the Einstein-Proca theory in the Newtonian regime, where the field frequency approaches the particle mass, $ω\t…

Gravitational synchronization in bosonic dark matter admixed neutron stars
Claudio Lazarte, Nicolas Sanchis-Gual, José A. Font
While the search for dark matter remains a central focus of modern astrophysics and high-energy physics, neutron stars provide natural laboratories in which the interaction between…

Non-linear stability analysis of -Proca stars
Claudio Lazarte, Nicolas Sanchis-Gual, José A. Font +1
Vector boson stars, also known as Proca stars, exhibit remarkable dynamical robustness, making them strong candidates for potential astrophysical exotic compact objects. In search…
