Structure of Quark Stars. (arXiv:1210.1910v1 [astro-ph.SR]):
This paper gives an brief overview of the structure of hypothetical strange
quarks stars (quark stars, for short), which are made of absolutely stable
3-flavor strange quark matter. Such objects can be either bare or enveloped in
thin nuclear crusts, which consist of heavy ions immersed in an electron gas.
In contrast to neutron stars, the structure of quark stars is determined by two
(rather than one) parameters, the central star density and the density at the
base of the crust. If bare, quark stars possess ultra-high electric fields on
the order of 10^{18} to 10^{19} V/cm. These features render the properties of
quark stars more multifaceted than those of neutron stars and may allow one to
observationally distinguish quark stars from neutron stars.
