Episodic Torque-Luminosity Correlations and Anticorrelations of GX 1+4 [HEAP]

http://arxiv.org/abs/1701.04717


We analyse archival CGRO-BATSE X-ray flux and spin frequency measurements of GX 1+4 over a time span of 3000 days. We systematically search for time dependent variations of torque luminosity correlation. Our preliminary results indicate that the correlation shifts from being positive to negative on time scales of few 100 days.
