    Redshifting the Study of Cold Brown Dwarfs and Exoplanets: The Mid-infrared Wavelength Region as an Indicator of Surface Gravity and Mass by S. K. Leggett, Pascal Tremblin

    Published 2025-01-01
    “…We find that an absolute 4.5 μ m flux measurement constrains temperature, and the ratio of the 4.5 μ m flux to the 10–15 μ m flux is sensitive to gravity and less sensitive to metallicity. We identify 10 T dwarfs with red W2−W3 colors that are likely to be very-low-gravity, young, few-Jupiter-mass objects; one of these is the previously known COCONUTS-2b. …”
