Abstract:  The up, down and strange quarks are believed to be fundamental constituents of most of the matter around - and usually they are confined to the protons and neutrons and other similar particles known as hadrons. It is possible that at high density they are deconfined and may form larger clusters - namely compact heavy stars. Profuse astronomical data now available makes it interesting to see if indeed one can see evidence of such objects.
