Observability of Single Neutron Stars at SRG/eROSITA

A four-year sky survey with the use of the eROSITA telescope on board the Spektr-RG observatory with focusing optics will provide the best coverage in the soft (0.5–2 keV) and standard (2–10 keV) X-ray ranges, both in terms of sensitivity and angular resolution. We have investigated the possibility...

Summary:A four-year sky survey with the use of the eROSITA telescope on board the Spektr-RG observatory with focusing optics will provide the best coverage in the soft (0.5–2 keV) and standard (2–10 keV) X-ray ranges, both in terms of sensitivity and angular resolution. We have investigated the possibility of detecting various types of single neutron stars using eROSITA. Among the already known objects, eROSITA will be able to detect more than 160 pulsars, 21 magnetars, 7 central compact objects, all seven sources of the Magnificent Seven, and two other X-ray single neutron stars during the four-year mission. In addition, eROSITA is expected to be able to detect accreting single neutron stars, as well as discover new cooling neutron stars and magnetars.
