A Low-Dimensional Chemical Representation of High-Resolution Stellar Disk Spectra: Residual Abundance Signatures

Stellar abundances are generated by complex chemical enrichment pathways yet show strong correlation structure. We test how well high-quality spectra of low-α disk stars can be reconstructed using low-dimensional models. By validating model performance in flux space, we quantify and locate where residual information...
