Solid Bare Strange Quark Stars
The reason, we need three terms of ‘strange’, ‘bare’, and ‘solid’ before quark stars, is presented concisely though some fundamental issues are not certain. Observations favoring these stars are introduced. 1. Hadronic stability: why strange? Strange (quark) stars are quark stars with strangeness. What’s strangeness? Some peculiar cosmic ray events were discovered in 1947, with a strange nature...
متن کاملAre Pulsars Bare Strange Stars?
It is believed that pulsars are neutron stars or strange stars with crusts. However we suggest here that pulsars may be bare strange stars (i.e., strange stars without crust). Due to rapid rotation and strong emission, young strange stars produced in supernova explosions should be bare when they act as radio pulsars. Because of strong magnetic field, two polar-crusts would shield the polar caps...
متن کاملLow-mass bare strange stars
Strange stars with low masses are suggested to exist in reality, the origin of which could be via accretion-induced collapse (AIC) of white dwarfs. Such a strange star is likely bare, and would thus spin very fast, even to a period of < 0.1 ms. Strange stars with low masses may differ from those with solar-masses in various astrophysical appearances. Observations to test this “low-mass” idea ar...
متن کاملRadiation from hot bare strange stars
We present the results of numerical simulations of stationary, spherically out-flowing, e ± pair winds, with total luminosities of L = 10 35 − 10 42 ergs s −1. These results have direct relevance to the emission from hot, bare, strange stars, which are thought to be powerful sources of pairs created by the Coulomb barrier at the quark surface. The spectra of emergent photons and pairs are calcu...
متن کاملSurface Electric Field of Bare Strange Stars
The surface electric characteristics of bare strange stars are investigated with the inclusion of the boundary effect. The thickness of the electron layer where pairs can be spontaneously created is calculated as a function of the bag parameters. We find that previous estimates are representative for bag parameters within rather wide range, and therefore our results favor the thermal radiation ...
