Rr Lyrae Stars in the Macho Database
The MACHO Project has catalogued 8000 RR Lyrae stars in the Large Magellanic Cloud, 1800 in the Galactic bulge, and 50 in the Sgr dwarf galaxy. These variables are excellent distance indicators, and are used as tools to study the structure of the Large Magellanic Cloud and the bulge. The large datasets also probe uncommon pulsation modes. A number of double-mode RR Lyrae stars (RRd) are found i...

متن کاملBinary Microlensing Events from the MACHO Project
We present the lightcurves of 21 gravitational microlensing events from the first six years of the MACHO Project gravitational microlensing survey which are likely examples of lensing by binary systems. These events were manually selected from a total sample of ∼ 350 candidate microlensing events which were either detected by the MACHO Alert System or discovered through retrospective analyses o...

متن کاملCalibration of the MACHO Photometry Database
The MACHO Project is a microlensing survey that monitors the brightnesses of ∼60 million stars in the Large Magellanic Cloud (LMC), Small Magellanic Cloud, and Galactic bulge. Our database presently contains about 80 billion photometric measurements, a significant fraction of all astronomical photometry. We describe the calibration of MACHO two-color photometry and transformation to the standar...
