Uncovering stellar atmospheres with gravitational microlensing telescopes
M. Dominik
A strong differential magnification over the face of the source star passing the caustic created by a binary lens star allows to measure its radial intensity profile with an angula…
Uncovering galactic and extragalactic planets by gravitational microlensing
M. Dominik
With its planet detection efficiency reaching a maximum for orbital radii between 1 and 10 AU, microlensing provides a unique sensitivity to planetary systems similar to our own ar…
Determining the abundance of extragalactic planets
M. Dominik
Gravitational microlensing provides a unique technique to reveal information about extragalactic planets. A network of at least four 2m-class telescopes distributed around the nort…
PLANET II: A Microlensing and Transit Search for Extrasolar Planets
Penny D. Sackett, M. D. Albrow, J. -P. Beaulieu +16
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily difficult to detect directly in optical light. Ca…
The PLANET microlensing follow-up network: Results and prospects for the detection of extra-solar planets
M. Dominik, M. D. Albrow, J. -P. Beaulieu +19
Among various techniques to search for extra-solar planets, microlensing has some unique characteristics. Contrary to all other methods which favour nearby objects, microlensing is…
Detecting planets around stars in nearby galaxies
G. Covone, R. de Ritis, M. Dominik +1
The only way to detect planets around stars at distances of several kpc is by (photometric or astrometric) microlensing observations. In this paper, we show that the capability of…
