Hyperons in Neutron Stars
In this work I briefly review some of the effects of hyperons on the properties of neutron and proto-neutron stars. In particular, I revise the problem of the strong softening of the EoS, and the consequent reduction of the maximum mass, induced by the presence of hyperons, a puzzle which has become more intringuing and difficult to solve because of the recent measurements of the unusually high...
متن کاملConstraining the Mass & Radius of Neutron Stars in Globular Clusters
We analyze observations of eight quiescent low-mass X-ray binaries in globular clusters and combine them to determine the neutron star mass-radius curve and the equation of state of dense matter. We determine the effect that several uncertainties may have on our results, including uncertainties in the distance, the atmosphere composition, the neutron star maximum mass, the neutron star mass dis...
متن کاملOne Mass-Radius relation for Planets, White Dwarfs and Neutron Stars
We produce the simple formula for the radius, R, of a cold body: ( 4 3 πρo) 1/3 R = M p y 1 + y I where y = M/Mp, M is the total mass, J = √ 1− y/y ch and I = J/ [
متن کاملModel-independent Mass-Radius Constraint for Neutron Stars
While model-independent limits are always interesting, a limit on neutron star radius as a function of mass attains special interest in light of recent interpretations of the periodic as well as quasi-periodic oscillations (QPOs) in brightness of X-rays emitted from neutron stars that are accreting matter from a low-mass companion. Here we derive such a limit based only on well accepted princip...
متن کاملParity Violation, the Neutron Radius of Lead, and Neutron Stars
The neutron radius of a heavy nucleus is a fundamental nuclear-structure observable that remains elusive. Progress in this arena has been limited by the exclusive use of hadronic probes that are hindered by large and controversial uncertainties in the reaction mechanism. The Parity Radius Experiment at the Jefferson Laboratory offers an attractive electro-weak alternative to the hadronic progra...
