Stellar age compression in spectroscopic estimates can produce apparent rapid thick-disk formation signatures without requiring an intrinsically bursty history.
Ages inferred for red giant stars via machine learning are generally insensitive to hyperparameters and architecture but somewhat sensitive to training set choice, especially for the oldest, coolest, and lowest-metallicity stars.
C/N/O abundance patterns indicate that some α-rich young red giants are merger or mass-transfer products rather than genuinely young stars with anomalous chemistry.
