Science and technical progress at the Palomar Testbed Interferometer
Abstract
The Palomar Testbed Interferometer (PTI) is a long-baseline, near-infrared interferometer located on Palomar Mountain. PTI has been in operation since 1997 and is used for extensive science observing as well as technical development. I will review the recent progress at PTI covering both science and instrumentation work. The science topics include fundamental stellar properties, novae, and an evaluation of all calibrator observations. The technical work includes the narrow-angle phase scanning mode and installation of the integrated optics combiner IONIC.
Additional Information
© 2008 Society of Photo-Optical Instrumentation Engineers (SPIE). PTI was designed for an operational lifetime of 3 years, but has produced scientifically relevant results for over 10 years. This is the result of the work and dedication of many people, in particular the project architect Mark Colavita and our excellent observers, Jean Mueller and Kevin Rykoski. In the last two years, the following have provided particular operations and development support to PTI: A. Boden, E. Hovland, M. Ireland, B. Lane, M. Muterspaugh, B. Thompson and G. Vasisht. Thanks to G. van Belle and M. Ireland for providing material for this review.Attached Files
