Abstract

SPICA (Stellar Parameters and Images with a Cophased Array) is a 6-telescope (6T) visible instrument for the CHARA Array (Center for High Angular Resolution in Astronomy) at Mount Wilson Observatory. It uses single mode fibers for feeding the interferometric spectrograph, which offers three different spectral resolutions: R=140, R=4000, and R=14000. CHARA/SPICA has been mainly designed for large programs (surveys) in the domain of stellar fundamental parameters but also permits fast imaging thanks to the 15 baselines and the large number of spectral channels (60 in low resolution mode). SPICA is made of the visible instrument SPICA-VIS and of a new H-band, 6T, ABCD combiner performing group delay and phase delay tracking. In this paper, we present the first light results of SPICA.
