Photonic spectro-interferometry with SCExAO/FIRST at the Subaru Telescope: towards H-alpha imaging of protoplanets
Sébastien Vievard, Manon Lallement, Elsa Huby +27
FIRST is a post Extreme Adaptive-Optics (ExAO) spectro-interferometer operating in the Visible (600-800 nm, R~400). Its exquisite angular resolution (a sensitivity analysis of on-s…
Single-aperture spectro-interferometry in the visible at the Subaru telescope with FIRST: First on-sky demonstration on Keho'oea (α Lyrae) and Hokulei (α Aurigae)
Sébastien Vievard, Elsa Huby, Sylvestre Lacour +20
FIRST is a spectro-interferometer combining, in the visible, the techniques of aperture masking and spatial filtering thanks to single-mode fibers. This instrument aims to deliver…
Caractérisation et intégration de composants d'optique intégrée sur l'interféromètre fibré FIRST au télescope Subaru pour l'étude des protoplanètes en accrétion
Kévin Barjot
Protoplanets accreting matter seem to feature a strong emission at wavelength and the contrast of the system is then weaker at these wavelengths and thus more accessibl…
First light of the FIRST visible fibered interferometer upgrade at the Subaru telescope
Kevin Barjot
FIRSTv2 (Fibered Imager foR a Single Telescope version 2) is the upgrade of a post-AO spectro-interferometer (FIRST) that enables high contrast imaging and spectroscopy at spatial…
