VizieR Online Data Catalog: Exoplanetary parameters for 18 bright stars (Ligi+, 2016)
Abstract
We performed interferometric measurements from 2010 to 2013 using the VEGA/CHARA instrument. VEGA is a spectro-interferometer working at visible wavelengths ([450-850]nm) at medium (6000) or high (30000) spectral resolution. It takes advantage of the CHARA baselines, which range from 34 to 331 m, to reach a maximum spatial resolution of ~0.3 millisecond of arc. VEGA is able to recombine the light coming from two to four of the six one-meter telescopes hosted by the CHARA array. The telescopes are arranged in a Y shape, which allows a wide range of orientations and thus a rich (u,v) coverage. Our observations were performed using three telescopes at medium spectral resolution and at observing wavelengths generally ranging between 650 and 730nm. This allowed us to reach an average of 1.9% uncertainty on angular diameters.
