Improvements on the structure of strange stars

This paper presents the structure of strange-star models, including the effects of a specific hypothetical few-quark bound state (quark-alpha). The general features of these stellar objects are discussed and analyzed in detail. It is shown that this modification to the strange-matter picture would make it possible to interpret the 'glitch' phenomenon observed in many pulsars in terms of features possessed by such objects. For low-mass stars it is found that the structure consists entirely of quark-alpha matter, forming a new branch of stable compact stars.
