  1. Robo-AO: Demo Period Nicholas Law

  2. The Demo Period • 4 weeks on the Palomar 60” • Q2 2011 • Mission: do lots of great science

  3. What’s unique to Robo-AO? • Large surveys • High efficiency • Continual availability • Great sky coverage • Visible-light & high speed imaging

  4. Demo Period Goals • Variety of science programs • Extragalactic • Transients • Stars • Planets • ... • Cover all Robo-AO unique capabilities • Large surveys • High efficiency • Visible-light AO • High NIR Strehl • Resulting in great science... and a large group of papers

  5. Survey Programs • Binarity survey • all spectral types, companions down to brown dwarfs for most • cover range of stellar parameter space with one instrument and one coherent survey

  6. Monitoring Trent Dupuy 2008, 2009

  7. High availability programs New Old Subtraction • The Palomar Transient Factory finds 1 transient candidate every ~10 minutes • Many found near galactic nuclei - how do we separate them?

  8. High-speed, high-resolution imaging 5/17/2010 Astronomy Tea Talk 2

  9. How much time is one month? • Overheads • 35-40 secs: telescope pointing & settling • 20 secs: Centering on target & verification • 10 secs: WFS calibration, wait for loop to close • Assume: • no science in first week • 50% uptime • 30% weather losses • Conservatively ~60 hours, or 1800 targets at 2 mins per target • However, we need about 5000 targets for contingency!

  10. Types of demo programs • Large, 1000 targets • Need to be very exciting papers -- only 2-3 possible • High-risk if incomplete • Medium, 100-300 targets • 10+ projects • Lower risk • Others • eg. transient followup (equiv. to 4m in sensitivity...)

  11. Demo period capabilities • General AO imaging • NIR & Visible [specific NIR camera TBD] • Dithering, standard observation sequences, etc. • Visible-light high-speed imaging • Efficiency will improve throughout run • Likely semi-robotic system • Probably manual target lists to start with • Maybe some simple scheduling by end of demo

  12. Decision process • Projects defined by September • Robo-AO team will collaborate, provide data, and support for data reduction, in exchange for paper authorship • Mini-TAC process within Robo-AO team • Current science team: • C. Baranec, R. Dekany, J. Johnson, M. Kasliwal, M. van Kerkwijk, S. Kulkarni, N. Law, T. Morton, E. Ofek, A. Ramaprakash, R. Riddle, S. Tendulkar
