Polarimetric interferometry combines milliarcsecond angular resolution with sensitivity to scattered light and can therefore probe both dust formation around evolved stars and dust survival at the inner rims of planet-forming disks. At optical and near-infrared wavelengths, however, the many oblique reflections in an i...

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...
