Astronomers have used the James Webb Space Telescope to capture the first complete 0.6–14 micron spectra of six brown dwarfs with known viewing angles, according to a new preprint on arXiv (https://arxiv.org/abs/2603.24662). The study examined five roughly 133-million-year-old L dwarfs from the AB Doradus moving group and one 500-million-year-old T dwarf from the Oceanus group, employing NIRSpec Prism and MIRI LRS instruments (R100). With a small sample size of just six objects, the team built spectral energy distributions to estimate temperatures, radii, masses, and gravity, while identifying molecules such as water, methane, CO, and CO2. They focused on the 8–11 micron silicate absorption feature that traces cloud structure, finding that four of five L dwarfs match the trend of stronger absorption in equator-on views, though one near pole-on object was an outlier with unusually deep absorption. The preprint notes a tentative link between peak silicate wavelength and inclination angle but highlights unexpected spectral diversity overall. As this is a preprint and not yet peer-reviewed, with limitations including the small sample that makes trends preliminary, the authors call for future atmospheric retrievals to probe cloud composition.
