Dr. Rachel Rampy, of W.M. Keck Observatory, will offer a talk entitled “Laser Guide Stars for Adaptive Optics” at the Imiloa Astronomy Center’s in Hilo, at 7 p.m., on Friday, July 19. The talk is part of the next Maunakea Skies program, and will focus on why astronomers benefit from creating artificial stars.
The turbulent atmosphere, which is responsible for twinkling stars, poses significant limitations on the capabilities of large ground based telescopes. Only in the past two decades has the technology of adaptive optics begun allowing astronomers to overcome this.
This talk will provide an overview of how adaptive optics technology functions, and describe how it is enhanced by the use of laser beacons. Rampy recently joined the Adaptive Optics team at the W. M. Keck Observatory after completing a doctorate in physics at the University of California, Santa Cruz, in February.
