With a mass of around three-quarters of our Sun crammed into a ball that could sit comfortably inside Manhattan, the compact object XMMU J173203.3-344518 is certainly remarkable.
The lightest detectedAt 77 percent of a solar mass, XMMU J173203.3-344518 isn't merely record-breaking; it's downright confusing. Neutron stars have no business being so petite.strange star
Comparing their results with strange matter equations and speculative models for their creation in supernovae, the team agreed this weird little object still has all of the hallmarks of a hypothetical strange star. Quarks happen to come in a variety of forms or flavors. 'Up' and 'down' flavors mix and match to form protons and neutrons. With sufficient pressure, down quarks can transform into up quarks, which in turn can switch into another flavor – a strange quark.
