ARTEMiS (Automated Robotic Terrestrial Exoplanet Microlensing Search) - A possible expert-system based cooperative effort to hunt for planets of Earth mass and below
M. Dominik, K. Horne, A. Allan +12
(abridged) The technique of gravitational microlensing is currently unique in its ability to provide a sample of terrestrial exoplanets around both Galactic disk and bulge stars, a…
An anomaly detector with immediate feedback to hunt for planets of Earth mass and below by microlensing
M. Dominik, N. J. Rattenbury, A. Allan +6
(abridged) The discovery of OGLE 2005-BLG-390Lb, the first cool rocky/icy exoplanet, impressively demonstrated the sensitivity of the microlensing technique to extra-solar planets…
High-precision astrometry on the VLT/FORS1 at time scales of few days
P. F. Lazorenko, M. Mayor, M. Dominik +3
We investigate the accuracy of astrometric measurements with the VLT/FORS1 camera and consider potential applications. The study is based on two-epoch (2000 and 2002/2003) frame se…
Adaptive Contouring -- an efficient way to calculate microlensing light curves of extended sources
M. Dominik
The availability of a robust and efficient routine for calculating light curves of a finite source magnified due to bending its light by the gravitational field of an intervening b…
Lens binarity vs limb darkening in close-impact galactic microlensing events
M. Dominik
Although point caustics harbour a larger potential for measuring the brightness profile of stars during the course of a microlensing event than (line-shaped) fold caustics, the eff…
Can microlensing fold caustics reveal a second stellar limb-darkening coefficient?
M. Dominik
Dense high-precision photometry of microlensed stars during a fold-caustic passage can be used to reveal their intensity profiles from which the temperature of the stellar atmosphe…
Revealing stellar brightness profiles by means of microlensing fold caustics
M. Dominik
With a handful of measurements of limb-darkening coefficients, galactic microlensing has already proven to be a powerful technique for studying atmospheres of distant stars. Survey…
Probing the atmosphere of the bulge G5III star OGLE-2002-BUL-069 by analysis of microlense H alpha line
A. Cassan, J. P. Beaulieu, S. Brillant +25
We discuss high-resolution, time-resolved spectra of the caustic exit of the binary microlensing event OGLE 2002-BUL-69 obtained with UVES on the VLT. The source star is a G5III gi…
High-Precicison Limb-Darkening Measurement of a K3 Giant Using Microlensing
Dale L. Fields, M. D. Albrow, J. An +21
We obtain high-precision limb-darkening measurements in five bands (V, V_E, I_E, I, and H) for the K3 III (Teff=4200 K, [Fe/H]=+0.3, log(g)=2.3) source of the Galactic bulge microl…
Microlensing Constraints on the Frequency of Jupiter Mass Planets
B. Scott Gaudi, M. D. Albrow, Jin H. An +17
Microlensing is the only technique likely, within the next 5 years, to constrain the frequency of Jupiter-analogs. The PLANET collaboration has monitored nearly 100 microlensing ev…
A robust and efficient method for calculating the magnification of extended sources caused by gravitational lenses
M. Dominik
To determine the magnification of an extended source caused by gravitational lensing one has to perform a two-dimensional integral over point-source magnifications in general. Sinc…
Where are the binary source galactic microlensing events?
M. Dominik
Though there have been some galactic microlensing events which show a clear signature of a binary lens, no event has yet been claimed as due to lensing of a binary source. Here I a…
