Refined orbital solution and quiescent variability in the black hole transient GS 1354-64 (= BW Cir)
Astrophysical Journal, Supplement Series 181:1 (2009) 238-243
Abstract:
In Casares et al. we presented the first radial velocity curve of the companion star to BW Cir which demonstrates the presence of a black hole in this historical X-ray transient. But these data were affected by aliasing and two possible periods at 2.5445 days and 2.5635 days were equally possible. Here we present new spectroscopic data that enable us to break the 1-year aliasing and confirm 2.5445 days as the correct orbital period. We also present R-band photometry over 14 years, which reveals the presence of important flaring activity dominating the light curves. © 2009. The American Astronomical Society.
