TITLE: Invitation to the 2nd Workshop on Exoplanet Studies in support of space observatories: 2017 March 02 Dear BAA Member, The second workshop* on amateur observations of exoplanets (including those in support of the Twinkle and ARIEL space missions) will be held on Thursday, March 02 from 11:00-13:30 in Room G21A on the ground floor of Senate House, Malet St, University College London, WC1E 7HU. BAA members and others interested in exoplanet studies are invited to attend this meeting. This is an exciting time in astronomy with, for instance, the announcement just yesterday of the remarkable discovery of the first system of 7 Earth-sized planets orbiting another star**. The workshop will start with a series of short talks followed by an hour or so of active discussion to which all are welcome to participate. Speakers from the professional and amateur community will give talks on progress towards the goal for amateurs to observe relatively bright stars that host one or more exoplanets. A BAA Exoplanet Working Group, set up following the first meeting, will report back to the community and the Twinkle team will present the science case for the amateur campaign and introduce the list of target stars involved. The challenge of precision photometry required to monitor exoplanet transits of their parent star will be discussed along with plans for data analysis, the development of analytical tools, and the potential for collaboration with other organisations including schools via the ORBYTS programme. On the agenda are 10-minute talks by BAA members, including a progress update by our working group, namely: Mark Trapnell - Amateur observing programmes and working together Sam Anahory - Proposed exoplanet group Mark Salisbury - Some examples of exoplanet transit observations Richard Miles - Challenges of millimagnitude photometry It is expected that time will be available during the afternoon for follow-up informal discussion involving active observers and the Twinkle team, as well as a more detailed consideration of project proposals.
