Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
n-point Gravitational Lenses with 5(n-1) Images
Sun Hong Rhie
It has been conjectured (astro-ph/0103463) that a gravitational lens consisting of n point masses can not produce more than 5(n-1) images as is known to be the case for n = 2 and 3…
Addendum to Astro-ph/0207612: Reflection Symmetry of Cusps in Gravitational Lensing
Sun Hong Rhie
A contour plot of positive iso-J curves is shown for a gravitational binary lens epsilon_2 = 0.1883 and ell = 0.687. The caustic curve is made of 4-cusped central caustic (so-calle…
Reflection Symmetry of Cusps in Gravitational Lensing
Sun Hong Rhie
Criticality in graviational microlensing is an everyday issue because that is what generates microlensing signals which may be of photon-challenged compact objects such as black ho…
The Microlensing Event MACHO-99-BLG-22/OGLE-1999-BUL-32: An Intermediate Mass Black Hole, or a Lens in the Bulge
D. P. Bennett, A. C. Becker, J. J. Calitz +5
We present an re-analysis of the longest timescale gravitational microlensing event discovered to date: MACHO-99-BLG-22/OGLE-1999-BUL-32, which was discovered by both the MACHO and…
Line Caustic Revisted: Which distance is in ?
Sun Hong Rhie
The line caustic behavior has been discussed since Chang and Refsdal (1979) mentioned inverse-square-root-of-the-distance dependence of the amplification of the images near the cri…
