Pulsar glitches in a strangeon star model. II. The activity

WH Wang, XY Lai, EP Zhou, JG Lu… - Monthly Notices of the …, 2021 - academic.oup.com
Glitch is supposed to be a useful probe into pulsar's interior, but the underlying physics
remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of inertia …
