Direct Temperature Map Estimation in Optical Long Baseline Interferometry
2016
Proceedings of the SPIE Astronomical Telescopes + Instrumentation Conference on Optical and Infrared Interferometry and Imaging V (SPIE-ATI'16)
We present a method to recontruct temperature map directly from spectro-interferometric data. It uses a sparse coding method to describe each pixel as a blackbody. Results are shown on the Herbig Be HD98922. Aside from recovering the mean environment temperature of 1654K in agreement with the photometry, this technique allows us to study the temperature distribution in the first astronomical units around the star.
