Dust in the Very Metal-poor Galaxy Sextans A with JWST. I. Characterizing the Evolved Stellar Population of Sextans A Based on JWST Observations and Stellar Evolution Models

The nearby star-forming dwarf galaxy Sextans A offers a unique window into galaxy evolution in the early Universe, owing to its extremely low metallicity (∼0.01–0.07 Z _⊙ ). Recent JWST imaging of Sextans A spanning 1–21  μ m enables a detailed characterization of its dusty stellar populations and i...
