We have observed the neutron star low-mass X-ray binary SAX J1810.8−2609 in quiescence with XMM-Newton. SAX J1810.8−2609 is one of the faintest non-pulsing neutron star low-mass X-ray binaries in quiescence and previously only had upper limits on its quiescent thermal emission. We found SAX J1810.8−2609 at the same 0.5-10 keV, unabsorbed luminosity as the previous quiescent observation in 2003, = Ĺ 1.5 10 X 32 erg s −1 . We show that the spectrum requires both thermal and nonthermal components,doi:10.3847/1538-4357/aaa6d3 fatcat:ikctav7wdbavpkl55slpwdatxy
