A multi-wavelength view of the isolated neutron star eRASSU J065715.3+260428

J. Kurpas, A. M. Pires, A. D. Schwope +6

The X-ray source eRASSU J065715.3+260428 was identified as a likely thermally emitting isolated neutron star in a search in the SRG/eROSITA All-Sky Survey. We investigated the natu…
