Astronomical spectra as language: Order-agnostic foundation model for low-SNR reconstruction and stellar parameter prediction
Summary Large-scale spectroscopic surveys contain numerous low-SNR stellar spectra that are difficult to analyze with traditional pipelines but remain valuable for Galactic archaeology, chemical-evolution studies, and population-level stellar characterization. We propose an order-agnostic foundation model that represen...
