Monitoring LMXBs with the Faulkes Telescopes

The Faulkes Telescope Project is an educational and research arm of the Las CumbresObservatory Global Telescope Network (LCOGTN). It has two 2-metre robotic telescopes,located at Haleakala on Maui (FT North) and Siding Spring in Australia (FT South). It isplanned for these telescopes to be complemented by a research network of eighteen 1-metre telescopes, along with an educational network of twenty-eight 0.4-metre telescopes, providing 24 hour coverage of both northern and southern hemispheres.We have been conducting a monitoring project of 13 low-mass X-ray binaries (LMXBs) using FT North since early 2006. The introduction of FT South has allowed us to extend this to monitor a total of 30 LMXBs (see target list, Section 4). New instrumentation will allow us to expand this project to include both infrared wavelengths (z and y band) and spectroscopy. Brighter targets (~ 16 - 18 mag.) are imaged weekly in V, R and i' bands (SNR ~ 50), while fainter ones (andgt; 18 mag.) are observed only in i' band (SNR ~ 20). We alter this cadence in response to our own analysis or Astronomers Telegrams (ATels)
