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 ...

What can neutron stars reveal about the equation of state of dense matter? [PDF]
EPJ Web of Conferences, 2020 Neutron stars are astrophysical objects of extremes, reaching the highest densities we can observe in the cosmos, and probing matter under conditions that cannot be recreated in terrestrial experiments.

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 ...

A novel solution to the hyperon-puzzle in neutron stars [PDF]
EPJ Web of ConferencesHyperons are baryons with strangeness content and heavier than nucleons. Due to the high densities in the neutron star interior, they are energetically allowed to appear.

High-energy emissions from neutron star mergers [PDF]
EPJ Web of Conferences, 2019 In 2017, LIGO-Virgo collaborations reported detection of the first neutron star merger event, GW170817, which is accompanied by electromagnetic counterparts from radio to gamma rays.

Physical Review D, 2022 The fundamental nature of dark matter is entirely unknown. A compelling candidate is Twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces. This predicts mirror neutron stars made entirely of mirror nuclear matter. We find their structure using realistic equations of state, robustly modified based on first-

Bayesian Model Selection of Unified Neutron Star EOSs in Multi-messenger Era
Yuanzineng kexue jishu, 2023 The equation of state (EoS) of neutron star matter plays a key role in both the structure and evolution of a neutron star. However, as lattice QCD faces significant difficulties in simulating dense matter, only effective models can be relied on to unveil
