  Recently there is a suggestion about the star RXJ1856.5$-$3754, being a
possible candidate for quark star. While from the estimates of the radiation
radius, given by the authors, it does not seem to fit with any of the known
models for such stars, the mass radius diagram admits the possibility of this
being a quark star of mass ${\rm M_\odot<M<1.4M_\odot}$, provided the radius
mentioned is the actual radius of the star.
