Resolving gravitational microlensing events with long - baseline optical interferometry . Prospects for the ESO Very Large Telescope Interferometer
Until now, the detailed interpretation of the observed microlensing events has suffered from the fact that the physical parameters of the phenomenon cannot be uniquely determined from the available astronomical measurements, i.e. the photometric lightcurves. The situation will change in the near-future with the availability of long-baseline, sensitive optical interferometers, which should be ab...
متن کاملResolving the Future of Astronomy with Long-Baseline Interferometry
We present six H band interferometric images of cool starspots on the chromospherically active giant Lambda Andromedae. Images span ∼75% of the rotational period with a cadence of ∼1 week. The data were obtained using all six telescopes in the CHARA array with the MIRC beam combiner. Model solutions show cool starspots evenly distributed in longitude. The starspots have an average covering fact...
متن کاملGravitational Microlensing with the Space Interferometry Mission
The Space Interferometry Mission (SIM), with its launch date planned for 2005, has as its goal astrometry with ∼ 1 μ arcsecond accuracy for stars as faint as 20th mag. If the SIM lives to expectations it can be used to measure astrometric displacements in the light centroid caused by the gravitational microlensing in the events detected photometrically from the ground. The effect is typically ∼...
متن کاملPerspective of long baseline optical interferometry
This article is a sort of sequel of the earlier extensive review by Saha (1999a) where emphasis was laid down on the ground based single aperture, as well as on the working long baseline optical interferometers (LBI) situated at the various observatories across the globe that are producing a large amount of astronomical results. Since the future of high resolution astronomy lies with the new ge...
متن کاملA self-calibration approach for optical long baseline interferometry imaging
Current optical interferometers are affected by unknown turbulent phases on each telescope. In the field of radio-interferometry, the self-calibration technique is a powerful tool to process interferometric data with missing phase information. This paper intends to revisit the application of self-calibration to Optical Long Baseline Interferometry (OLBI ). We cast rigorously the OLBI data proce...
