Autonomous laser-adaptive-optics for few-meter-class telescopes

Robo-AO is the first autonomous laser adaptive optics system and science instrument operating on sky. The system robotically executes large scale surveys, monitors long-term astrophysical dynamics and characterizes newly discovered transients, all at the visible diffraction limit. The first of many envisioned systems has finished over 130 nights of science observing at the Palomar Observatory 60-inch telescope (with over 18,000 robotic observations executed).

The Robo-AO project, led by Principal Investigator Christoph Baranec, with Software Lead Reed Riddle, Project Scientist Nicholas Law, Co-Investigator A. N. Ramaprakash, and students and collaborators, is a collaboration between Caltech Optical Observatories and the Inter-University Centre for Astronomy and Astrophysics. It is partially funded by the National Science Foundation under grants AST-0906060, AST-0960343 and AST-1207891, the Office of Naval Research under grant N00014-11-1-0903, by the Mount Cuba Astronomical Foundation, by a gift from Samuel Oschin and by the Indo-US Science and Technology Forum.

July 13th, 2015 In the summer of 2014, we successfully tested using an infrared avalanche photodiode with the Robo-AO system as both a high-speed camera and tip-tilt sensor. The results of that effort have just been accepted for publication in the Astrophysical Journal.

June 10th, 2015 We are wrapping up our last Robo-AO observing run at Palomar Observatory in a few nights. The last five years have been fantastic at Palomar and we couldn't have been successful without the support of such a dedicated and helpful observatory staff. Thank you all! We will soon be hard at work preparing for our next deployment - stay tuned for an announcement soon.

March 4th, 2015 Robo-AO has discovered the second known case of a planet residing in a quadruple star system. The findings help researchers understand how multiple star systems can influence the development and fate of planets. Read more in NASA's Jet Propulsion Laboratory News and in an Institute for Astronomy press release.

Robo-AO discovered the orange-red star in the upper left, bringing the total number of known stars in the system to four. The planet, a gas giant, orbits its primary star (yellow) in about a year's time. Image copyright: Karen Teramura, UH IfA.

January 27th, 2015 Visible light adaptive optics imaging from the Robo-AO system helped in accurately determining the relative sizes of the five Earth-sized planets orbiting their ancient (11.2 billion years old) host star, Kepler-444. Read more in the news and the journal paper led by the University of Birmingham's Dr. Tiago Campante.
