After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Abstract Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program
Analysis Group was organized to study the effect of stellar contamination on space-based …

The distortions of absorption line profiles caused by photospheric brightness variations on
the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) shifts …

In many star–planet systems discovered so far, the innermost planet orbits within only a few
stellar radii. In these systems, planets could become in situ probes of the extended stellar …

We present temperature maps of RS CVn star λ Andromedae, reconstructed from
interferometric data acquired in 2010 and 2011 by the Michigan Infra-Red Combiner …

We have built and characterized, to our knowledge, the first six-telescope discrete beam
combiner (DBC) for stellar interferometry in the astronomical J-band. It is the DBC with the …

We present new angular diameter measurements for 33 stars from the Navy Precision
Optical Interferometer, reaching uncertainties on the limb-darkened diameter of 2% or less …

We have built and characterized a six-telescope near-infrared discrete beam combiner
(DBC) for stellar interferometry using the technique of ultrafast laser inscription (ULI). The 3D …

We present spectroscopic data obtained by IUE of the chromospherically active binary
system λ And in the period (1978–1994). The ultraviolet observations show indication of …

The newest generation of radial velocity spectrographs are impressive instruments that are
capable of making RV measurements with extreme precision (< 30 cm s− 1). The biggest …
