Abstract

Arising from: F. Özel Nature 441, 1115-1117 (2006) In a theoretical interpretation of observational data from the neutron star EXO 0748-676, Özel concludes that quark matter probably does not exist in the centre of neutron stars. However, this conclusion is based on a limited set of possible equations of state for quark matter. Here we compare Özel's observational limits with predictions based on a more comprehensive set of proposed quark-matter equations of state from the literature, and conclude that the presence of quark matter in EXO 0748-676 is not ruled out.
