On the Perturbative Picture and the Chang-Refsdal Lens Approximation for Planetary Microlensing
Keming Zhang
Under the perturbative picture of planetary microlensing, the planet is considered to act as a uniform-shear Chang-Refsdal lens on one of the two images produced by the host star t…

A Mathematical Treatment of the Offset Microlensing Degeneracy
Keming Zhang, B. Scott Gaudi
The offset microlensing degeneracy, recently proposed by Zhang et al. (2022), has been shown to generalize the close-wide and inner-outer caustic degeneracies into a unified regime…

A Ubiquitous Unifying Degeneracy in Two-Body Microlensing Systems
Keming Zhang, B. Scott Gaudi, Joshua S. Bloom
While gravitational microlensing by planetary systems provides unique vistas on the properties of exoplanets, observations of a given 2-body microlensing event can often be interpr…
