Neutron star HESS J1731-347 may be a ‘strange’ star

Researchers at the Institut für Astronomie und Astrophysik in Germany have found evidence that suggests the extremely tiny neutron star, HESS J1731-347, may in fact be a “strange” star. In their paper published in the journal Nature Astronomy, Victor Doroshenko, Valery Suleimanov, Gerd Pühlhofer and Andrea Santangelo, describe a new approach to recalculate the distance of the star and their discovery of characteristics that suggest it could be of the strange star variety.
