Intercomparison of Brown Dwarf Model Grids and Atmospheric Retrieval Using Machine Learning
The Astrophysical Journal, 2023 Understanding differences between substellar spectral data and models has proven to be a major challenge, especially for self-consistent model grids that are necessary for a thorough investigation of brown dwarf atmospheres.

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...

Atmospheric circulation of exoplanets
地球与行星物理论评, 2023 To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is ...

The Oceanus Moving Group: A New 500 Myr Old Host for the Nearest Brown Dwarf
The Astrophysical Journal, 2023 We report the discovery of the Oceanus moving group, a ≈500 Myr old group with 50 members and candidate members at distances 2–50 pc from the Sun, using an unsupervised clustering analysis of nearby stars with Gaia DR3 data.

Possible nuclear fusion of deuteron in the cores of Earth, Jupiter, Saturn, and brown dwarfs
AIP Advances, 2020 Many brown dwarfs have recently been discovered as sub-stellar objects in which deuteron thermonuclear fusion is taking place. Although Jupiter and Saturn emit nearly twice as much heat as they absorb from the Sun, their internal heat-generation ...
