Microlensing Event MOA-2007-BLG-400: Exhuming the Buried Signature of a Cool, Jovian-Mass Planet
Subo Dong, I. A. Bond, A. Gould +55
We report the detection of the cool, Jovian-mass planet MOA-2007-BLG-400Lb. The planet was detected in a high-magnification microlensing event (with peak magnification A_max = 628)…
A Low-Mass Planet with a Possible Sub-Stellar-Mass Host in Microlensing Event MOA-2007-BLG-192
D. P. Bennett, I. A. Bond, A. Udalski +44
We report the detection of an extrasolar planet of mass ratio q ~ 2 x 10^(-4) in microlensing event MOA-2007-BLG-192. The best fit microlensing model shows both the microlensing pa…
OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion?
Subo Dong, Andrew Gould, Andrzej Udalski +81
We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These…
Discovery of a Jupiter/Saturn Analog with Gravitational Microlensing
B. S. Gaudi, D. P. Bennett, A. Udalski +66
Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlens…
Observation of the first gravitational microlensing event in a sparse stellar field : the Tago event
A. Fukui, F. Abe, K. Ayani +17
We report the observation of the first gravitational microlensing event in a sparse stellar field, involving the brightest (V=11.4 mag) andclosest (~ 1 kpc) source star to date. Th…
SuprimeCam Observation of Sporadic Meteors during Perseids 2004
M. Iye, M. Tanaka, M. Yanagisawa +6
We report the serendipitous findings of 13 faint meteors and 44 artificial space objects by Subaru SuprimeCam imaging observations during 11-16 August 2004. The meteors, at about 1…
Discovery of a Cool Planet of 5.5 Earth Masses Through Gravitational Microlensing
J. -P. Beaulieu, D. P. Bennett, P. Fouque +46
In the favoured core-accretion model of formation of planetary systems, solid planetesimals accumulate to build up planetary cores, which then accrete nebular gas if they are suffi…
The Earliest Optical Observations of GRB 030329
K. Torii, T. Kato, H. Yamaoka +9
We present the earliest optical imaging observations of GRB 030329 related to SN 2003dh. The burst was detected by the HETE-2 satellite at 2003 March 29, 11:37:14.67 UT. Our wide-f…
The radiant of the Leonids meteor storm in 2001
Ken'ichi Torii, Mitsuhiro Kohama, Toshifumi Yanagisawa +1
We have measured the radiant of the Leonids meteor storm in November 2001 by using new observational and analysis techniques. The radiant was measured as the intersections of lines…
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…
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…
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…
Real-Time Difference Imaging Analysis of MOA Galactic Bulge Observations During 2000
I. A. Bond, F. Abe, R. J. Dodd +27
We describe observations carried out by the MOA group of the Galactic Bulge during 2000 that were designed to detect efficiently gravitational microlensing of faint stars in which…
Discovery of the optical counterpart and early optical observations of GRB990712
Kailash C. Sahu
We present the discovery observations of the optical counterpart of the gamma-ray burster GRB990712 taken 4.16 hours after the outburst and discuss its light curve observed in the…
