Efficient reduction of stellar contamination and noise in planetary transmission spectra using neural networks

arXiv:2602.10330v2 Announce Type: replace-cross Abstract: Context: JWST has enabled transmission spectroscopy at unprecedented precision, but stellar heterogeneities (spots and faculae) remain a dominant contamination source that can bias atmospheric retrievals if uncorrected....
