RXTE PCA observations of an ongoing Type II X-ray outburst from the SMC Be/X-ray binary XTE J0103-728 (SXP6.85) reveal a periodicity of 21.86 ± 0.11 days in pulse period measurements obtained between MJD 55435.76 to 55488.64. We interpret this as being due to orbital Doppler modulation of the neutron star spin period. From a fit to the pulse period measurements we derive:
Porbital = 21.86 ± 0.11 days Eccentricity = 0.26 ± 0.03 Ppulse = 6.8507 +/- 0.0001 seconds (on MJD 55465.49) Pdot = (8.4 ± 0.5)E-10 s/s Time of periastron passage = MJD 55457.5 ± 0.4
A plot of the pulse period measurements and best fit model can be found at www.astro.soton.ac.uk/~mjc/sxp6.85.ps A Swift TOO observation made on 2010-10-26 also detected this source.
