Long-term X-ray variability in GX 354-0.

KONG A.K.H., CHARLES P.A. and KUULKERS E.

Abstract (from CDS):

We report for the first time the detection of long-term X-ray variability in the bright bulge source GX 354-0 (=4U 1728-34) observed with the All Sky Monitor (ASM) on board the Rossi X-Ray Timing Explorer (RXTE). The 2-year RXTE ASM database reveals significant power at ∼ 72 days. Similar behaviour was seen in the 6-year Ariel 5 ASM database, but at a period of ∼ 63 days. The timescales and light curves resemble the ∼ 78 days modulation seen in Cyg X-2 and we therefore interpret this modulation in GX 354-0 as a super-orbital effect.
