Physical Parameter Eclipse Mapping

3D eclipse mapping

A light curve modelling and fitting program is presented for cataclysmic variable stars and related objects. It allows modelling of a three-dimensional disk in conjunction with the Roche-lobe filling secondary star, thus rendering it a very general tool for light curve analysis. Optimization of the solution is based on the maximumentropy algorithm. Some bench-mark tests are presented, and the g...

Eclipse mapping of accretion discs

The eclipse mapping method is an inversion technique that makes use of the information contained in eclipse light curves to probe the structure, the spectrum and the time evolution of accretion discs. In this review I present the basics of the method and discuss its different implementations. I summarize the most important results obtained to date and discuss how they have helped to improve our...

Toward Eclipse Mapping of Hot Jupiters

Recent Spitzer infrared measurements of hot Jupiter eclipses suggest that eclipse mapping techniques could be used to spatially resolve the day-side photospheric emission of these planets using partial occultations. As a first step in this direction, we simulate ingress/egress lightcurves for three bright eclipsing hot Jupiters and evaluate the degree to which parameterized photospheric emissio...

What can we learn from Accretion Disc Eclipse Mapping experiments?

The accretion disc eclipse mapping method is an astrotomographic inversion technique that makes use of the information contained in eclipse light curves to probe the structure, the spectrum and the time evolution of accretion discs in cataclysmic variables. This paper presents examples of eclipse mapping results that have been key to improve our understanding of accretion physics.
