MACHOs in M31? Absence of evidence but not evidence of absence
Jelte T. A. de Jong, Lawrence M. Widrow, Patrick Cseresnjes +9
We present results of a microlensing survey toward the Andromeda Galaxy (M31) carried out during four observing seasons at the Isaac Newton Telescope (INT). This survey is part of…
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…
Microlensing in M31; Preliminary lightcurves from MEGA
Jelte de Jong, Penny D. Sackett, Konrad Kuijken +3
One of the possible astrophysical solutions to the galactic dark matter problem is the presence of a significant amount of ``dark'' compact objects (MACHOs) in galactic dark matter…
Results from Microlensing Searches for Extrasolar Planets
Penny D. Sackett
Specially-designed microlensing searches, some of which have been underway for several years, are sensitive to extrasolar planets orbiting the most common stars in our Galaxy. Micr…
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…
Microlensing and the Physics of Stellar Atmospheres
Penny D. Sackett
The simple physics of microlensing provides a well-understood tool with which to probe the atmospheres of distant stars in the Galaxy and Local Group with high magnification and re…
