High precision photometry for exoplanet and time domain astronomy

RAS specialist discussion meeting: High precision photometry for exoplanet and time domain astronomy

10:30–15:30 on Friday 8 November 2019 in the Geological Society Lecture Theatre, Burlington House, Piccadilly, London W1J 0BG

Organisers:  Sarah Casewell (Leicester), Peter Wheatley (Warwick), Mike Goad (Leicester), Dan Bayliss (Warwick)



The UK has led the world in the use of high precision time-series photometry to detect transiting planets, first with the WASP survey and ULTRACAM and more recently with NGTS and HiPERCAM.  These facilities have opened a new window in exoplanet detection and characterisation, together with a wide range of time-domain phenomena. From space, the Kepler and TESS satellites have revolutionised the world of exoplanet detection, with the ability to detect Neptune to Earth-sized planets.  Both NGTS and TESS are observing at longer wavelengths than their predecessors, focusing on characterising Neptune and Earth-sized exoplanets around stars cooler than the sun. As they do, these facilities are observing millions of stars and are also discovering giant planets, eclipsing binaries, variable stars, pulsating white dwarfs, and many more unusual systems. They also probe stellar activity (e.g. flares) over a broad range of timescales.  These precision photometric observations are an invaluable resource for the astronomical community, providing months of high-cadence monitoring data that would be nigh-on impossible to obtain via open time on International observing facilities. They are also an excellent preparation for future facilities such as PLATO.
