Study by MOA of extra-solar planets in gravitational microlensing events of high magnification
I. A. Bond, N. J. Rattenbury, J. Skuljan +27
A search for extra-solar planets was carried out in three gravitational microlensing events of high magnification, MACHO 98-BLG-35, MACHO 99-LMC-2, and OGLE 00-BUL-12. Photometry w…
Photometry of pulsating stars in the Magellanic Clouds as observed in the MOA project
J. B. Hearnshaw, I. A. Bond, N. J. Rattenbury +24
A review of the MOA (Microlensing Observations in Astrophysics) project is presented. MOA is a collaboration of approximately 30 astronomers from New Zealand and Japan established…
Asteroseismological Observations of the Central Star of the Planetary Nebula NGC 1501
H. E. Bond, S. Kawaler, R. Ciardullo +17
We report on a global CCD time-series photometric campaign to decode the pulsations of the nucleus of the planetary nebula NGC1501. The star is hot and hydrogen-deficient, similar…
Study of variable stars in the MOA data base: long-period red variables in the Large Magellanic Cloud
S. Noda, M. Takeuti, F. Abe +31
One hundred and forty six long-period red variable stars in the Large Magellanic Cloud (LMC) from the three year MOA project database were analysed. A careful periodic analysis was…
Microlensing optical depth towards the Galactic bulge from MOA observations during 2000 with Difference Image Analysis
T. Sumi, F. Abe, I. A. Bond +27
We analyze the data of the gravitational microlensing survey carried out by by the MOA group during 2000 towards the Galactic Bulge (GB). Our observations are designed to detect ef…
Recent results by the MOA group on gravitational microlensing
P. Yock, I. Bond, N. Rattenbury +25
Recent work by the MOA gravitational microlensing group is briefly described, including (i) the current observing strategy, (ii) use of a high-speed parallel computer for analysis…
