Detection maps for five configurations of simulated point-like sources whose locations are pointed out by circles. Reconstruction results b𝒙 obtained with the proposed approach (bottom) are compared to S/N maps obtained with PACO (middle) and with the oracle version of PACO (top) assuming a perfect unmixing (not achievable in practice) between the objects of interest and the nuisance component for the computation of the nuisance parameters. Dataset: HIP 113283 (2015-06-27, #6), total parallactic rotation Δ𝜙 = 22.8 ◦ for 𝑇test = 64 temporal frames kept, see Sect. 3.1 for the detailed observation parameters. We used a detection threshold of 5 for all methods. -- astro-ph.IM

MODEL&CO: Exoplanet Detection In Angular Differential Imaging By Learning Across Multiple Observations

by Keith CowingOctober 12, 2024October 12, 2024

Direct imaging of exoplanets is particularly challenging due to the high contrast between the planet and the star luminosities, and their small angular separation. In addition to tailored instrumental facilities […]
