  25. Massive Star Binaries Workshop on Robotic Autonomous Observatories, Málaga

  26. Massive Star Binaries Workshop on Robotic Autonomous Observatories, Málaga

  27. X-ray Binaries Bright X-ray sources where material flows onto a compact object (neutron star or black hole) from its binary companion X-ray luminosity of 1034 - 1038 erg s-1 (cf. the Sun’s 1028 erg s-1) Temperature ~ 10,000,000 K Around 300 known XRBs in our Galaxy Workshop on Robotic Autonomous Observatories, Málaga

  28. Lifecycle of stars Workshop on Robotic Autonomous Observatories, Málaga

  29. Low-Mass X-ray Binaries (LMXBs) Donor usually K or M star (small, red, faint, long-lived, low-mass) Long-lived (~107 – 109 years) System’s brightness dominated by disc Workshop on Robotic Autonomous Observatories, Málaga

  30. Workshop on Robotic Autonomous Observatories, Málaga

  31. LMXBs For once, big isn’t better Star doesnt dominate overall brightness Great testbeds for gravitation/space-time theories Does what a quasar does (assuming you dont have the time or funding to wait for a quasar !) Workshop on Robotic Autonomous Observatories, Málaga

  32. LMXB Monitoring 30 sources split between FTN & FTS (NS & BH) Monitored once per week since 2006 Frequency increased after alert or if we see interesting activity Future plans include infra-red, more telescopes, spectroscopy Workshop on Robotic Autonomous Observatories, Málaga
