Neutron-mirror neutron mixing and neutron stars [PDF]
The European Physical Journal C, 2021 AbstractThe oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark stars $$n-n'$$

Hyperons in Neutron Stars [PDF]
Universe, 2021 I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons in the core of neutron stars and I review the main techniques and many-body methods used to ...

Properties and Dynamics of Neutron Stars and Proto-Neutron Stars [PDF]
, 2022 Following new developments in the measurement of gravitational waves from neutron–star mergers and the modification or construction of particle colliders to reach larger densities, we are entering a new era, during which we can begin to understand dense ...

Gravitoastronomy with neutron stars [PDF]
, 2004 Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Hyperons and Neutron Stars [PDF]
Proceedings of The Modern Physics of Compact Stars 2015 — PoS(MPCS2015), 2013 Abstract In this work we briefly review some of the effects of hyperons on neutron and proto-neutron star properties. We revise the problem of the strong softening of the EoS, and the consequent reduction of the maximum mass, due to the presence of hyperons, a puzzle which has become more intriguing due the recent measurements of the unusually high ...

Microlensing neutron stars [PDF]
Astronomy & Astrophysics, 2002 We investigate the chances that neutron stars act as the lense in a gravitational microlensing event towards the galactic bulge or a spiral arm. The observation of neutron stars by means of gravitational microlensing would allow the estimation of neutron star masses independently of the property of being a pulsar in a binary system.

PROPERTIES OF NEUTRON STARS [PDF]
Compact Stars, 2004 I review attempts made to determine the properties of neutron stars. I focus on constraints on the maximum mass that a neutron star can have, and on attempts to measure neutron-star radii. So far, there appears to be only one neutron star for which there is strong evidence that its mass is above the canonical 1.4 Msun, viz., Vela X-1, for which a mass ...

Simulations of X-ray bursts and superbursts [PDF]
, 2015 Observations of neutron star in binary systems provide powerful constrains on the physics at the surface of neutron stars. During the accretion of matter from the companion star, periodic nuclear explosion are triggered in the outer layers of the neutron
