Future high contrast interferometric observations with the Very Large Telescope Interferometer (VLTI) require nanometer level control of optical path variations to preserve fringe stability and maximize sensitivity. Within the framework of the PLANETES project, a dedicated laser metrology system is being developed to m...

The FIRST-PL instrument on the Subaru Telescope enables a new observational capability: measuring stellar spin orientations for indirect constraints on exoplanet orbital geometry. We describe the instrument and demonstrate data reduction techniques to measure the spin orientation of Humu (Altair), whose apparent size i...

We present PLANETES, a technology development project that aims at demonstrating GRAVITY-style dualfield interferometry into the J band. Building on PIONIER’s legacy in short-wavelength interferometry and GRAVITY’s breakthroughs in dual-field operation, this demonstrator integrates dual-field injection, integratedoptic...
