Summary. Virtually all detection and characterisation methods are based on time- domain data. This invited talk gave an overview of some recent results in the field, highlighting some of the time-series-specific challenges encountered along the way. In particular it focussed on planetary transits: how to detect shallow, rare transits in noisy data, and how to model them with extreme accuracy to extract information about the transiting planet’s atmosphere. Space-based transit surveys also constitute an extraordinary goldmine of information on stellar variability, and the talk touched briefly upon some recent statistical work in that field.

Asteroseismology Don Kurtz Jeremiah Horrocks Institute, University of Central Lancashire, Preston, PR1 2HE, UK email: [email protected] Invited Talk

Summary. In 1926 in the opening paragraph of his now-classic book, The Internal Consti- tution of the Stars, Sir Arthur Eddington lamented, “What appliance can pierce through the outer layers of a star and test the conditions within?” While he considered theory to be the proper answer to that question, there is now an observational answer: asteroseismology. This talk introduced the concepts of asteroseismology, then looked at a selection of discoveries made for “ticking things” with the micromagnitude precision light curves of the Kepler Mission.
