Strehl ratio and visibility in long-baseline stellar interferometry.
The relationship between Strehl ratio (S), the parameter most often used by those in the adaptive optics field, and visibility (V), the parameter of most interest to those working in interferometry, is investigated. It is found that if the atmospheric turbulence is assumed to be Kolmogorov, V approximately S for high Strehl ratios. At low Strehl ratios, both simulations and an analytical formul...
متن کاملCepheid distances from infrared long-baseline interferometry
Using our interferometric angular diameter measurements of seven classical Cepheids reported in Kervella et al. (2003, Paper I), complemented by previously existing measurements, we derive new calibrations of the Cepheids Period–Radius (P–R) and Period–Luminosity (P–L) relations. We obtain a P–R relation of logR = [0.767 ± 0.009] logP + [1.091 ± 0.011], only 1σ away from the relation obtained b...
متن کاملAltair’s Oblateness and Rotation Velocity from Long-Baseline Interferometry
We present infrared interferometric angular size measurements for the A7IVV star Altair which indicate a non-circular projected disk brightness distribution. For preprints, please contact: [email protected].
متن کاملDegree-1 Earth deformation from very long baseline interferometry measurements
[1] The presence of degree-1 deformations in very long baseline interferometry (VLBI) measurements is detected for the first time. We compare VLBI measurements with the deformation field predicted using a GPS-determined load moment. Degree-1 series in the center of figure frame have root mean square values up to 3 and 1.5 mm in the up and horizontal components respectively. The predicted baseli...
متن کاملMultiplicity of Galactic Cepheids from long-baseline interferometry
Context. More than 60% of Cepheids are in binary or multiple systems. Studying such systems could lead to a better understanding of the age and evolution of Cepheids. These are also useful tools to estimate the mass of Cepheids, and constrain theoretical models of their pulsation and evolution. Aims. We aim at determining the masses of Cepheids in binary systems, as well as their geometric dist...
