Abstract

Imaging large intensity gradients for rapid rotators, complicated spot patterns on rotating RS CVn binaries, and diffuse disk emission around Young Stellar Objects requires advanced imaging methods beyond the current image reconstruction paradigms in optical/infrared interferometry. We report on the ongoing development of SQUEEZE, a flexible software for optical and infrared interferometry capable of simultaneous model-fitting and image reconstruction, and possessing useful new capabilities such as imaging on a spheroid. We treat the problem of the local minimas due to the "missing phase" and explore the use of non-pixel-based reconstructions within the Bayesian evidence and compressed sensing frameworks.
