Programme
| 10:30 – 11:00 | Introduction to morning session and TTV recap – Roger Dymock |
| 11:00 – 12:00 | Analysis of TTVs using Exoplanetpie – Peter Vuylsteke Demo of a new software package for analysing Transit Timing Variations |
| 12:00 – 12:30 | Where have all the Tatooines gone? A geometrical perspective on the detection of exoplanets orbiting non-eclipsing binaries – Paul Dooley Exoplanets in orbit around binary stars (sometimes known as “Tatooines”) form a fascinating category of exoplanetary systems. To date, photometric detection of such exoplanets has concentrated on eclipsing binary systems. However, most binary systems do NOT eclipse, meaning that a significant number of potential Tatooines may be going undetected. Here we use simulation to review and illustrate the geometry and challenges in detection of exoplanets orbiting non-eclipsing binary systems. |
| 12:30 – 13:30 | Lunch break |
| 13:30 – 13:50 | Introduction to afternoon session – Rodney Buckland |

| 14:20 – 14:30 | Break |
| 14:30 – 15:00 | Reducing effects of stellar variability using Lombe-Scargle techniques – Daniel Barbos Can Earth-based telescopes help reduce noise in data from space telescopes by modelling stellar variability using Lomb-Scargle techniques? |
