Is the compact object associated with HESS J1731-347 a strange quark star?

he analysis of the central compact object within the supernova (SN) remnantHESS J1731-347 suggests that it has a small radius and, even moreinterestingly, a mass of the order or smaller than one solar mass (Doroshenkoet al. 2022, Nature Astronomy). This raises the question of which astrophysicalprocess could lead to such a small mass, since the analysis of various types ofSN explosions indicate that is it not possible to produce a neutron star (NS)with a mass smaller than about $1.17 M_\odot$. Here we show that masses of theorder or smaller than one solar mass can be obtained in the case of strangequark stars (QSs) and that it is possible to build a coherent astrophysicalscenario explaining not only the mass and the radius of that object, but alsoits slow cooling suggested in various analyses. Moreover, we will show that QSscan fulfill all the limits on masses and radii of the other astrophysicalobjects discussed in Doroshenko et al. 2022 and can also explain the possibleexistence of objects having a mass of the order or larger than $2.5 M_\odot$,as suggested by the analysis of GW190814.
