Where the Stream Strikes
Direct-impact accretion turns incoming material into a concentrated region of heat.
A conceptual close-up of direct-impact accretion: transferred gas strikes the receiving brown dwarf’s atmosphere and heats a luminous region to roughly 8,900 kelvin. The image depicts the mechanism inferred from observations, rather than a resolved view of the system.
THE OBSERVATION
What we can actually see.
Brightness changes and spectral analysis in the reported binary support a hotspot where transferred material reaches the accretor. The system is not spatially resolved into the detailed gas stream and glowing atmospheric structure shown here.

FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article begins with a rapidly orbiting, mass-transferring brown-dwarf pair, then expands to the small young objects and unusual infrared chemistry Webb is investigating. It separates present accretion heating from a possible future change in stellar status. This frame focuses on direct-impact accretion turns incoming material into a concentrated region of heat.
