Georgia State University Professor Emeritus of Astronomy Hal McAlister will be giving a talk, “Georgia State’s CHARA Array Zooms in on the Universe,” at 3:00pm on Monday, October 7th, in the Honors College Auditorium (100 Auburn Avenue). The talk, part of Georgia State’s Centennial Speaker Series, will focus on GSU’s Center for High Angular Resolution Astronomy (CHARA) and its six-telescope array on Mount Wilson, California. The array, which began operation in 2005, can resolve detail “equivalent to the angular size of a nickel seen from a distance of 10,000 miles” 1.
Since 2005, 94 peer-reviewed journal articles have been published based on CHARA data, along with related articles, reports, and more. Take a look at these articles to see what research GSU scientists are conducting with the CHARA Array:
- Characterization of the Red Giant HR 2582 Using the CHARA Array, E.K. Baines et al., The Astrophysical Journal, 772, 16, 2013.
- Binary Star Orbits. III. Revisiting the Remarkable Case of Tweedledum and Tweedledee, B.D. Mason et al., The Astronomical Journal, 140, 242, 2010.
