Georgia State University and ALPAO Sign Agreement for Adaptive Optics Upgrade on Telescopes at CHARA Array - KFDAGeorgia State University’s Center for High Angular Resolution Astronomy (CHARA) and the French company ALPAO have signed a contract for the development of an adaptive optics upgrade for the CHARA Array, the largest optical interferometer array in the world. Mount Wilson, Calif. ALPAO will develop and manufacture six deformable mirrors, each composed of 6. These deformable mirrors represent state- of- the- art instrumentation to correct for the effect of atmospheric turbulence. The goal of this technique, known as adaptive optics, is to observe stars and their surroundings as clearly as they would appear in space.“We are delighted to begin this new stage in CHARA's scientific mission with deformable mirrors from ALPAO,” said CHARA Array Director Theo ten Brummelaar.

Georgia State University and ALPAO Sign Agreement for Adaptive Optics Upgrade on Telescopes at CHARA Array.
Ten Brummelaar and collaborators from Georgia State have carefully considered the most effective approaches to enhance the sensitivity of the instrument. The main goal of this work, funded by the U. S. National Science Foundation, is to add deformable mirrors to each of the six 1- meter telescopes, completing the development and implementation of fast adaptive optics capabilities at each telescope.
To simplify the telescope upgrade, the size of the deformable mirror will match the corresponding flat mirror now used on the six CHARA telescopes. The optical surface will form an ellipse measuring 1.
Computer control of the actuators will push the surface into a shape that compensates for turbulence in Earth's atmosphere. Together, these modifications should allow the telescopes to measure stars three times fainter than now possible.
The new system will increase the number of nights with high- quality data by about a factor of three in the summer and five in the winter, with much faster observation times. New important areas of study will include the study of high- interest targets, such as dusty debris disks around young stars and accretion disks and gas flows around newborn stars.“ALPAO is proud to work with CHARA, the world's highest angular resolution telescope at near- infrared wavelengths,” said Vincent Hardy, sales manager of ALPAO. All of our team is very excited to be a part of this project for the future of the interferometric telescope and the development of astronomical science.”About CHARAEncouraged by the success of the program of binary star speckle interferometry initiated at Georgia State in 1. Center for High Angular Resolution Astronomy (CHARA) was established in 1. Such an instrument is able to measure the sizes of thousands of stars, see the individual components of binary stars gravitationally bound together in orbits having periods as short as one day, and even detect and image surface details on stars whose existence has only been inferred.

With nearly 3. 00 people in attendance, the CHARA Array was dedicated on October 4, 2. On September 1. 9, 2. Array achieved starlight fringes on its 3. Arrington Remote Operations Center for the CHARA Array, located on the Georgia State campus in Atlanta, was dedicated on February 2.
This facility is permitting GSU faculty, staff and students to participate in observing activities at the Array on Mt. Wilson, enabling the remote control of all CHARA facilities from across the country. With this in mind, CHARA has entered into several collaborations with groups offering unique instruments or technologies for enhanced performance. At present these collaborations include a joint observing effort with astronomers from the Laboratoire d'Etudes Spatiales et d'Instumentation en Astrophysique (LESIA) of the Observatoire de Paris who have located their .
A collaboration with astronomers from the University of Michigan has led to the development of an imaging beam combiner which has already produced the first images of stellar surfaces and close binary stars. An agreement between GSU and L'Observatoire de la C. Finally, a joint project between CHARA and astronomers from the University of Sydney (Australia) has led to the development of a fourth beam combiner with significantly improved sensitivity to fainter objects while also providing measurements of very high precision. These international collaborations have brought significant added value to the science capabilities of the CHARA Array. For more information: http: //www.
