Tidal Love numbers of Proca stars

Proca stars [1] are everywhere regular, asymptotically flat self-gravitating solitons composed of complex, massive vector bosons, forming a macroscopic, star-sized, Bose-Einstein condensate. They

Rotating axion boson stars

We construct and study rotating axion boson stars (RABSs). These are the spinning generalisations of the spherical gravitating solitons recently introduced in [1]. RABSs are asymptotically flat,

Dirac star with SU(2) Yang-Mills and Proca fields

We study spherically symmetric strongly gravitating configurations supported by nonlinear spinor fields and non-Abelian SU(2) Yang-Mills/Proca magnetic fields. Regular asymptotically flat solutions

Axion boson stars

We study novel solitonic solutions to Einstein-Klein-Gordon theory in the presence of a periodic scalar potential arising in models of axion-like particles. The potential depends on two parameters:

Ultracompact vector stars

We analytically investigate a new family of horizonless compact objects in vector-tensor theories of gravity, called ultracompact vector stars. They are sourced by a vector condensate, induced by a

Nonlinear Dynamics of Spinning Bosonic Stars: Formation and Stability.

Analysis suggests bosonic stars have different stability properties in the scalar (vector) case, which is tentatively relate to its toroidal (spheroidal) morphology.

Soliton boson stars, Q-balls and the causal Buchdahl bound

Self-gravitating non-topological solitons whose potential admits multiple vacua are promising candidates for exotic compact objects. Such objects can arise in several extensions of the Standard Model

General relativistic boson stars

There is accumulating evidence that (fundamental) scalar fields may exist in nature. The gravitational collapse of such a boson cloud would lead to a boson star (BS) as a new type of a compact

Kerr black holes with scalar hair.

We present a family of solutions of Einstein's gravity minimally coupled to a complex, massive scalar field, describing asymptotically flat, spinning black holes with scalar hair and a regular

Models of rotating boson stars and geodesics around them: new type of orbits

We have developed a highly accurate numerical code capable of solving the coupled Einstein-Klein-Gordon system, in order to construct rotating boson stars in general relativity. Free fields and

Nonexistence of Baryon Number for Black Holes. II

In a previous paper we showed that a static (nonrotating) black hole cannot be endowed with exterior scalar-meson or massive vector-meson fields. Here we show that the same is true for massive spin-2

The dynamical evolution of the perturbed ground-state boson stars in numerical relativity is reported on, with implications on the actual existence and the formation of bosonStars in an astrophysical environment.

Cosmological Constraints on Bose-Einstein-Condensed Scalar Field Dark Matter

Despite the great successes of the cold dark matter (CDM) model in explaining a wide range of observations of the global evolution and the formation of galaxies and large-scale structure in the

Accretion of dark matter by stars.

This work focuses here on light fields with mass m_{B}, such as axions and axionlike candidates, and shows that collapse of the host star to a black hole is avoided by efficient gravitational cooling mechanisms.

Dynamical Boson Stars

This work discusses important varieties of boson stars, their dynamic properties, and some of their uses, concentrating on recent efforts.

Construction and physical properties of Kerr black holes with scalar hair

Kerr black holes (BHs) with scalar hair are solutions of the Einstein–Klein–Gordon field equations describing regular (on and outside an event horizon), asymptotically flat BHs with scalar hair
