2 ADASS XVII, Sept. 2007 1 The eSTAR network

3 ADASS XVII, Sept. 2007 2 eSTAR in a nutshell

4 ADASS XVII, Sept. 2007 3 How does it work? User Agent User Agent Embedded Agent Embedded Agent CREDIT: Liverpool John Moores University UI

5 ADASS XVII, Sept. 2007 4 Other Clients Other Clients Event Network Reactive case? User Agent User Agent Embedded Agent Embedded Agent UI Alert Client Alert Client

6 ADASS XVII, Sept. 2007 5 The eSTAR/HTN Protocol Registry User Resource Resource Discovery Phase 0 Scoring Request Confirm Reject Observed Update Fail

7 ADASS XVII, Sept. 2007 6 Parallel Strands Two parallel strands –VOEvent standard –HTN and eSTAR standards VOEvent standard has been designed to –transport timely information concerning transient events HTN standards has been designed to –allow the recipient of an event message to negotiate for, and obtain, follow-up observations to these reported events from a heterogeneous collection of networked telescopes

9 ADASS XVII, Sept. 2007 8 Smarter than average? How well should one bit of software believe other bits of software when they tell it somewhere? Currently running simulations in Exeter –keeping track of scores from telescopes and whether they actually returned data, i.e. are they “lying” to us? –using this to modify our decision making process in the future, hopefully weighting things towards the telescopes that don’t “lie” about how well they can perform observations Emerging social conventions?

13 ADASS XVII, Sept. 2007 12 Doing real science

14 ADASS XVII, Sept. 2007 13 PLANET/Robonet-1.0 Campaign First look observations of OGLE-EWS events –first look for MOA will be done next season Continuous monitoring of ongoing OGLE and MOA events –maximise planet discovery rate Rapid response to possible anomalies in real-time –trigger override observations –event notification Closed-loop system

17 ADASS XVII, Sept. 2007 16 Anomaly hunting Real time data reduction Real time data analysis –See “An anomaly detector with immediate feedback to hunt for planets of Earth mass and below by microlensing”, 2007, MNRAS, M.

19 ADASS XVII, Sept. 2007 18 …and finally?

20 ADASS XVII, Sept. 2007 19 Conclusions Autonomous observing –IVOA standard VOEvent messaging –HTN standard RTML messaging –eSTAR represents a “turn-key” system Operating in three modes –event driven –long term monitoring –reactive follow-up See http://www.estar.org.uk/ for more information
