Editing Strange star (section)

==Characteristics==
Early work on strange quark matter suggested that it would be a homogeneous liquid, but other models propose<ref name=prashanth/> a heterogeneous alternative with positively charged "[[strange quark nugget]]s" embedded in a negatively charged electron gas.<ref name=PageReddy2006/> This structure decreases the stars' external electric field and  density variation from previous theoretical expectations, with the result that such stars appear nearly indistinguishable from ordinary neutron stars. 

Other theoretical work contends that:{{blockquote|A sharp interface between quark matter and the vacuum would have very different properties from the surface of a neutron star.<ref name=rajagopal/>|author=|title=|source=}}
Addressing key parameters like [[surface tension]] and [[electrical force]]s that were neglected in the original study, the results show that as long as the surface tension is below a low critical value, the large [[strangelet]]s are indeed unstable to fragmentation and strange stars naturally come with complex strangelet crusts, analogous to those of neutron stars.<ref name=rajagopal/>
