Radii, masses, and ages of 18 bright stars using interferometry and new estimations of exoplanetary parameters
Roxanne Ligi, Orlagh Creevey, Denis Mourard +7
Accurate stellar parameters are needed in numerous domains of astrophysics. The position of stars on the H-R diagram is an important indication of their structure and evolution, an…
GRAVITY: the VLTI 4-beam combiner for narrow-angle astrometry and interferometric imaging
N. Blind, F. Eisenhauer, S. Gillessen +23
GRAVITY is the second generation Very Large Telescope Interferometer instrument for precision narrow-angle astrometry and interferometric imaging in the Near Infra-Red (NIR). It sh…
Spectral and spatial imaging of the Be+sdO binary phi Persei
D. Mourard, J. D. Monnier, A. Meilland +25
The rapidly rotating Be star phi Persei was spun up by mass and angular momentum transfer from a now stripped-down, hot subdwarf companion. Here we present the first high angular r…
The GRAVITY metrology system: narrow-angle astrometry via phase-shifting interferometry
M. Lippa, N. Blind, S. Gillessen +26
The VLTI instrument GRAVITY will provide very powerful astrometry by combining the light from four telescopes for two objects simultaneously. It will measure the angular separation…
