ABYSS. III. Observing Accretion Activity in Young Stars Through Empirical Veiling Measurements
Stellar accretion plays an important role in the early stages of stellar evolution, particularly in Classical T Tauri Stars (CTTSs). Accretion of a CTTS can be related to different physical parameters such as effective temperature (Teff), age,…

Semiempirical versus Theoretical Stellar Population Models: A Comparison with Star Clusters
Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity, and reddening of star clusters from their integrated spectra. Using a sample of 129 star clusters with high-quality spectra, we analyze…
