摘要
The Center for High Angular Resolution Astronomy (CHARA) Array is a six-element interferometer with baselines ranging from 34 to 331m. The Array has had many upgrades in recent years including new beam combiners: MYSTIC is a 6T combiner for K-band; SPICA is a 6T combiner for the visible R-band; and SILMARIL is a 3T combiner for high sensitivity in the H- and K-bands. A seventh, mobile telescope is now on site for use with fiber optics for beam transport. Observing time is available to the community through a program funded by NSF. The observing programs are solicited and peer-reviewed by NSF's NOIRLab. Here we summarize the scientific work and the on-going technical advances of the CHARA Array.
