Constraints on Neutron Star Structure from the Clocked X-Ray Burster 1RXS J180408.9−342058
The Astrophysical Journal, 2023 Type I X-ray bursts are rapid-brightening transient phenomena on the surfaces of accreting neutron stars (NSs). Some X-ray bursts, called clocked bursters, exhibit regular behavior with similar light-curve profiles in their burst sequences.

Phase-resolved Deadtime of the Crab Pulsar Using IXPE Data
The Astrophysical JournalAfter receiving an X-ray photon, an X-ray detector is not operational for a duration known as deadtime. It is detector specific and its effect on the data depends upon the luminosity of the source.
