Precision ephemerides for gravitational-wave searches: I. Sco X-1
Duncan Galloway, Sammanani Premachandra, Danny Steeghs +3
Rapidly-rotating neutron stars are the only candidates for persistent high-frequency gravitational wave emission, for which a targeted search can be performed based on the spin per…
The origin of the tilted disk in the low mass X-ray binary GR Mus (XB 1254-690)
R. Cornelisse, M. M. Kotze, J. Casares +2
We present photometric and spectroscopic observations of the low mass X-ray binary GR Mus (XB 1254-690), and find strong evidence for the presence of a negative superhump with a pe…
A 420 day X-ray/optical modulation and extended X-ray dips in the short-period transient Swift J1753.5-0127
A. W. Shaw, P. A. Charles, A. J. Bird +6
We have discovered a \sim420d modulation, with associated X-ray dips, in RXTE-ASM/MAXI/Swift-BAT archival light-curves of the short-period (3.2h) black-hole X-ray transient, Swift…
A 2 hour periodic variation in the low mass X-ray binary Ser X-1
R. Cornelisse, J. Casares, P. A. Charles +1
Spectroscopy of the low mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ~2 hr periodic variability that is present in the three strongest emission line…
The nature of the X-ray transient MAXI J0556-332
R. Cornelisse, P. D'Avanzo, S. Campana +8
Phase-resolved spectroscopy of the newly discovered X-ray transient MAXI J0556-332 has revealed the presence of narrow emission lines in the Bowen region that most likely arise on…
Correlated Optical/X-ray Long-term Variability in LMXB 4U1636-536
I. C. Shih, P. A. Charles, R. Cornelisse
We have conducted a 3-month program of simultaneous optical, soft and hard X-ray monitoring of the LMXB 4U1636-536/V801 Ara using the SMARTS 1.3m telescope and archival RXTE/ASM an…
