Long-baseline interferometric observations in the Near Infrared reach angular resolutions on the order of milliarcseconds. With the long baselines of the CHARA array, science cases such as exozodiacal dust of early-type main sequence stars can be probed to study early-stage planet formation with percentage-precision vi...

The Center for High Angular Resolution Astronomy (CHARA) Array is a six-element interferometer at Mount Wilson Observatory with baselines ranging from 34 to 331m. The Array hosts a number of new or upgraded, six-telescope beam combiners that span the spectrum from the visible R-band to the near-infrared K-band with a r...

The suite called Stellar Parameters and Images with a Cophased Array (SPICA) has two interferometric instruments installed at the focus of the CHARA Array located at Mount Wilson, CA. SPICA is made of SPICA-VIS, a fiber-fed six-beam visible spectrograph with three spectral resolutions, and SPICA-FT, a six-beam near-inf...

Dual-field interferometry uses a bright reference star for real-time fringe tracking, allowing a second beam combiner to record long coherent integrations on a fainter off-axis science target. At the Center for High Angular Resolution Astronomy (CHARA) Array, we implement this mode using the six-telescope MIRC-X and MY...
