Chromaticity effects in microlensing by wormholes
(World Scientific, 2001-12)
We discuss the possibility that the stellar system Cyg OB2 No. 5 can be a gamma-ray source in the light of recent EGRET and radio data. This system is formed by an O7 Ia + Ofpe/WN9 contact binary. A third star, probably a ...
Microlensing by natural wormholes: theory and simulations
(American Physical Society, 2002-12)
We provide an in depth study of the theoretical peculiarities that arise in effective negative mass lensing, both for the case of a point mass lens and source, and for extended source situations. We describe novel observational ...
New Measurement of Microlensing Optical Depth and Examination of Blending in Microlensing Events
(AAS, 2004)
We present a new determination of the optical depth to microlensing to the Galactic bulge. We select a sample of 62 clump giant events (60 unique) and calulate the optical depth. With a detailed efficiency analysis we find ...
Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events
(2009)
To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of lensing light curves. However, it is known ...
A systematic fitting scheme for caustic-crossing microlensing events
(2009)
We outline a method for fitting binary-lens caustic-crossing microlensing events based on the alternative model parametrization proposed and detailed by Cassan. As an illustration of our methodology, we present an analysis ...
