A family of spacetimes suitable for describing the matter conditions of a static, spherically symmetric quantum vacuum is studied, as
A seemingly natural mechanism is proposed, that could stop the gravitational collapse of a very massive body. Without needing to
Strong cosmic censorship holds that given suitable initial data on a spacelike hypersurface, the laws of general relativity should determine,
We address the question concerning the maximum density, at which nuclei (and more generally -- nuclear structures) can exist in
The processes contributing to the evolution of an initially weak magnetic field in a differentially rotating star are reviewed. These
An analysis of the propagation of non stationary waves in the adiabatic region of stellar interior is presented. An equation
A family of spacetimes suitable for describing the interior of a non-rotational black hole is constructed. The stress-energy tensor is
We assess the impact of the trace element Ne-22 on the cooling and seismology of a liquid C/O white dwarf
Starting from the Helmholtz free energy we calculate analytically first- and second-order derivatives, as internal energy and specific heats, for
The preponderance of binary systems in all known stellar populations makes them exciting dynamical agents for research on topics as
We investigate the thermal, magnetic and rotational evolution of isolated neutron stars assuming that the dipolar magnetic field is confined
The cooling theory of isolated neutron stars is reviewed. The main cooling regulators are discussed, first of all, operation of
With Teragauss magnetic fields, surface gravity sufficiently strong to significantly modify light paths, central densities higher than that of a
We find a new mechanism of neutron star radiation wherein radiation is produced by the stellar interior. The source of
We examine the role of anisotropic turbulence on the shear instabilities in a stratified flow. Such turbulence is expected to
On the basis of the neutrino emission from the isotropic $^1$S$_0$ neutron superfluid vortexes in neutron star interiors, we propose
The importance of Cepheids is well known in many fields of astronomy. Section 2 introduces the Fourier decomposition, a tool
Nanocrystalline metals, i.e. metals in which the grain size is in the nanometer range, have a range of technologically interesting
The richness and very high accuracy of the observed frequencies of solar oscillations provide tight constraints on the structure of
Cooling of neutron stars (NSs) with the cores composed of neutrons, protons, and electrons is analyzed. The main cooling regulators
In the sixties,the first author and R.Kasanin have started developing a mean field theory of dense matter.This paper presents a
Be abundances of old, low metallicity halo stars have major implications on cosmic-ray origin, requiring acceleration out of fresh supernova
Several mechanisms based on neutrino oscillations can explain the observed motions of pulsars if the magnetic field in their interiors
We illustrate the approach to the use of asteroseismology to sound stellar interiors. We also present the spectroscopic and photometric
