Machine learning for exoplanet detection in high-contrast spectroscopy Combining cross correlation maps and deep learning on medium-resolution integral-field spectra

no code implementations22 May 2024 Rakesh Nath-Ranga, Olivier Absil, Valentin Christiaens, Emily O. Garvin

Through this paper, we demonstrate that ML techniques have the potential to improve the detection limits and reduce false positives for directly imaged planets in IFS datasets, after transforming the spectral dimension into a radial velocity dimension through a cross-correlation operation.

NA-SODINN: a deep learning algorithm for exoplanet image detection based on residual noise regimes

no code implementations6 Feb 2023 Carles Cantero, Olivier Absil, Carl-Henrik Dahlqvist, Marc Van Droogenbroeck

Supervised deep learning was recently introduced in high-contrast imaging (HCI) through the SODINN algorithm, a convolutional neural network designed for exoplanet detection in angular differential imaging (ADI) datasets.
