Discovery of torque reversal in the Be/X-ray binary pulsar GX 304-1

AD Chandra - arxiv preprint arxiv:2311.13303, 2023 - arxiv.org
We study the long-term spin period evolution of the Be/X-ray binary pulsar GX 304-1 and
discover a new torque reversal after nearly three years of spinning up. The averaged spin …
