, 2021 The destiny of a star is depending on the status of hydrogen fusion that it can reach after its formation. Stars have steady hydrogen fusion and can maintain their luminosity. Degenerate brown dwarfs (D-BD) have no energy supply from hydrogen fusion thus

Retrieval Study of Brown Dwarfs Across the L-T Sequence [PDF]
, 2022 A large suite of 228 atmospheric retrievals is performed on a curated sample of 19 brown dwarfs spanning the L0 to T8 spectral types using the open-source Helios-r2 retrieval code, which implements the method of short characteristics for radiative ...

PICASO 3.0: A One-dimensional Climate Model for Giant Planets and Brown Dwarfs
The Astrophysical Journal, 2023 Upcoming James Webb Space Telescope observations will allow us to study exoplanet and brown dwarf atmospheres in great detail. The physical interpretation of these upcoming high signal-to-noise observations requires precise atmospheric models of ...

A measurement of the wind speed on a brown dwarf [PDF]
Science, 2020 High winds in an extrasolar atmosphere Brown dwarfs are objects intermediate in mass between large planets and small stars, and their atmospheres share many characteristics with gas giant planets. Wind speeds in Solar System gas giant atmospheres can be derived by comparing the planet's rotational periods in the infrared (tracing

Atmosphere Models of Highly Irradiated Brown Dwarfs
, 2021 While highly irradiated brown dwarfs are rare, the handful of known systems provide a unique lens into irradiated atmospheres. Ultra-short-period brown dwarfs around white dwarfs can reach atmospheric temperatures hotter than many stars. Such objects are

Advanced Science, EarlyView.This study integrates rice immune perception, signal transduction, and resistance output into a multi‐omics framework. By combining high‐throughput sequencing, phenomics, and AI‐assisted design with marker‐assisted selection, gene editing, and rapid domestication, we aim to accelerate the precise breeding of disease‐resistant rice varieties by ...
