    The Shapes of Stellar Spectra
    Stellar atmospheres separate the hot and dense stellar interiors from the emptiness of space. Radiation escapes from the outermost layers of a star, carrying...

    The use of iteration factors for temperature correction in a stellar atmosphere when convective transport is present
    In a previous work (Paper I of this series), we presented a procedure for computing the temperature distribution in a stellar atmosphere under the constraint of...

    Very Low Mass Stars, Brown Dwarfs and Gas Giant Exoplanets
    Understanding the atmospheric and evolutive properties of very low mass stars, brown dwarfs, and gas giant exoplanets have been important challenges for...
