Verifying the cooling of the Cas A neutron star with HRC-S
Abstract
The central neutron star in Cassiopeia A (Cas A NS) has evidence from Chandra ACIS data for a rapid temperature decline (2-3% per decade). If this is correct, it is a crucial constraint on understanding the cooling of young NSs, and particularly on superfluidity in their cores. However, systematic uncertainties in ACIS data suggest the importance of a verification observation using another detector. A new HRC-S observation of Cas A in 2023 would provide this crucial cross-check.
