Oimodeler: a modular modelling software for optical interferometry

Résumé

It has been more than 20 years since optical-interferometric facilities first started producing spectro-interferometric data, and yet the number of general user tools able to handle this type of data properly is limited. Moreover, they often either focus on simple generic cases (e.g., simple grey geometrical models defined with analytical functions) or very specific objects (e.g., binaries, kinematics in emissions lines of circumstellar disks, stellar photospheres).

To overcome these limitations, we have developped oimodeler, a python-based optical-interferometric data modelling software allowing one to build complex models from various type of components ranging from simple geometrical to external outputs of radiative transfer models. The software allows one to add chromaticity (continuum, line and bands) and time-dependence easily. The code is object-oriented to be more flexible and easily expandable. Here we present its concept, implementation and some examples of fitting of real data. The code is available at https://github.com/oimodeler/oimodeler
