The Large Fiber Array Spectroscopic Telescope: status update of the prototype telescope

The Large Fiber Array Spectroscopic Telescope, a part of the Eric and Wendy Schmidt Observatory System (LFAST), is designing and building a new optical telescope composed of an array of small “unit telescopes”, which can be replicated economically and at scale to produce an arbitrarily large incoherent aperture. Our fi...

Radial velocity follow-up of \textit{Gaia} astrometric substellar companions: six confirmed brown dwarfs and 13 impostor binaries

With microarcsecond precision, \textit{Gaia} has made the astrometric discovery of substellar companions feasible. However, follow-up observations are needed to check on orbital solutions and rule out astrophysical false positives. We validate and characterise a sample of 20 \textit{Gaia} Data Release 3 (DR3) astrometr...

The NEID Earth Twin Survey. VI. Discovery of a Low-Mass Planet Orbiting HD 126053 and RV Signals Near the Rotation Periods of HD 168009 and HD 10780

Extreme precision radial velocity (EPRV) spectrographs are making strides in extending the limits of radial velocity exoplanet detection. Perhaps the best evidence for this is how readily EPRV instruments are facilitating the discovery and detailed characterization of small-amplitude planetary signals around stars that...
