Third family of compact stars within a nonlocal chiral quark model equation of state
(American Physical Society, 2019-03)
A class of hybrid compact star equations of state is investigated that joins by a Maxwell construction a low-density phase of hadronic matter, modeled by a relativistic mean-field approach with excluded nucleon volume, ...
Compact stars cooling and secular instability
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Entropy, complexity and disequilibrium in compact stars
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We used the statistical measurements of information entropy, disequilibrium and complexity to infer a hierarchy of equations of state for two types of compact stars from the broad class of neutron stars, namely, with ...
Countability and star covering properties
(ELSEVIER SCIENCE BV, 2011)
Whenever P is a topological property, we say that a topological space is star P if whenever U is an open cover of X, there is a subspace A subset of X with property P such that X = St(A, U). We study the relationships of ...
White dwarf stars
(Asociación Argentina de Astronomía, 2009)
White dwarfs are the most common end-product of stellarevolution, and as such contain valuable information about the evolutionof individual stars as well as about the star formation history andsubsequent evolution in our ...
On the extent of star countable spaces
(VERSITA, 2011)
For a topological property P, we say that a space X is star Pif for every open cover Uof the space X there exists Y aS, X such that St(Y,U) = X and Y has P. We consider star countable and star Lindelof spaces establishing, ...
A Photoionized Accretion Disk around a Young High-mass Star
(IOP, 2020)
We present high spatial resolution (52 au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/submillimeter Array. This O-type HMYSO is located at 2.38 kpc ...
Magnetosphere of an orbiting neutron star
(American Physical Society, 2020-03-15)
We conduct force-free simulations of a single neutron star undergoing orbital motion in flat spacetime, mimicking the trajectory of the star about the center of mass on a compact binary system. Our attention is focused on ...
EXACT AND QUASI-EXACT MODELS OF STRANGE STARS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We construct and compare in this work a variety of simple models for strange stars, namely, hypothetical self-bound objects made of a cold stable version of the quark-gluon plasma. Exact, quasi-exact and numerical models ...
