A light strange star in the remnant HESS J1731-347: Minimal consistency checks

چکیده

Context: Recently, Doroshenko and collaborators reported a very low-mass compact star, Central Compact Object named XMMU J173203.3-344518 inside the supernova remnant HESS J1731-347. Its tiny mass is at odds with all calculations of minimum masses neutron stars generated by iron cores, therefore (and even if not compellingly) it has been suggested to be {\it strange star}. Besides mass, radius surface temperature have extracted from data, whole body information should ultimately reveal this object truly consistent an exotic composition. Aims: To understand status in J1731-347 within existing models stars, including its prompt formation. Methods: The obtained on are compared theoretical performed usual using General Relativity as assumed theory gravitation handful cooling scenarios. A qualitative discussion showing consistency strange-matter driven scenario star provided. Results: We found that fits same quark recently employed explain radii NICER objects PSR J040+6620 J0030+0451, which both quantities were simultaneously determined. It also remarkable find simple devised $30\text{ yr}$ ago superconducting quarks provides overall good explanation temperature. Conclusions: conclude into ``strange star'' heavier can belong class constitute homogeneous type self-bound produced Nature.

Discovery of the Radio and X-ray Counterpart of Tev Γ-ray Source Hess J1731-347

We discover a faint shell-type radio and X-ray source, G353.6-0.7, associated with HESS J1731-347. G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4 GHz and 5 GHz), infrared (8 µm from the GLIMPSE Legacy Project and 21 µm from the Midcourse Space Experiment), and X-ray (0.1 keV-2.4 keV from the ROSAT survey and 5-20 keV from the INTEGRAL survey) data. The SNR, ce...

The Fastest Rotating Pulsar : a Strange Star ?

According to the observational limits on the radius and mass, PSR 1937+21 is probably a strange star, or some neutron star equations of state should be ruled out, if we alternatively suggest that a dipole magnetic field (rather than a quadrupole one) is relevant to its radio emission. In order to find solid evidence to shown that PSR 1937+21 is a strange star, it is strongly suggested to measur...
