Suppose, in a particular X-ray observation data set for a particular low-mass X-ray binary neutron star source, we find no QPO features, thermonuclear burst features or strong X-ray pulsations.
If neither of these features ( QPO, thermonuclear bursts or strong X-ray pulsations) are present in a given X-ray observation, then what other interesting features can be explored from the data set with the aim to get a suitable refereed publication?
