The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from
the role of compact objects in astrophysics to their detection through various methods …

We study an impact of self-interacting bosonic dark matter (DM) on various observable
properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses …

The idea of stable, localized bundles of energy has strong appeal as a model for particles. In
the 1950s, John Wheeler envisioned such bundles as smooth configurations of …

Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

A bstract We study the possibility that self-interacting bosonic dark matter forms star-like
objects. We study both the case of attractive and repulsive self-interactions, and we focus …

We derive an approximate analytical expression of the maximum mass of relativistic self-
gravitating Bose-Einstein condensates with repulsive or attractive| φ| 4 self-interaction. This …

Recently, the small value of the cosmological constant and its ability to accelerate the
expansion of the universe is of great interest. We discuss the possibility of forming of …

We construct the light escape cones of isotropic spot sources of radiation residing in special
classes of reference frames in the Kerr–de Sitter (KdS) black hole spacetimes, namely in the …

We consider the structure and physical properties of specific classes of neutron, quark, and
Bose-Einstein condensate stars in the conformally invariant Weyl geometric gravity theory …
