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…
A Lack of Planets in 47 Tucanae from an HST Search
Ronald L. Gilliland, T. M. Brown, P. Guhathakurta +21
We report results from a large Hubble Space Telescope project to observe a significant (~34,000) ensemble of main sequence stars in the globular cluster 47 Tucanae with a goal of d…
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…
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…
