Towards A Census of Earth-mass Exo-planets with Gravitational Microlensing

J. P. Beaulieu, E. Kerins, S. Mao +26

Thirteen exo-planets have been discovered using the gravitational microlensing technique (out of which 7 have been published). These planets already demonstrate that super-Earths (…

Extended-Source Effect and Chromaticity in Two-Point-Mass Microlensing

Ondrej Pejcha, David Heyrovsky

We explore the sensitivity of two-point-mass gravitational microlensing to the extended nature of the source star, as well as the related sensitivity to its limb darkening. We demo…

Computing Limb Darkening Coefficients from Stellar Atmosphere Models

David Heyrovsky

We explore the sensitivity of limb darkening coefficients computed from stellar atmosphere models to different least-squares fitting methods. We demonstrate that conventional metho…

OGLE 2004-BLG-254: a K3 III Galactic Bulge Giant spatially resolved by a single microlens

A. Cassan, J. -P. Beaulieu, P. Fouque +37

We present an analysis of OGLE 2004-BLG-254, a high-magnification and relatively short duration microlensing event in which the source star, a Bulge K3-giant, has been spatially re…

Velocity Effects on the Deflection of Light by Gravitational Microlenses

David Heyrovsky

We study the influence of general lens and source velocities on the gravitational deflection of light by single and two-point-mass microlenses with general axis orientation. We dem…

Measuring Stellar Limb Darkening by Gravitational Microlensing

David Heyrovsky

Observations of microlensing transit events can be used to measure the limb darkening of the lensed star. We discuss the advantages and drawbacks of several microlensing light curv…
