Limits RegistryTeide 1, found in the Pleiades cluster, was confirmed in 1995 as the first bona fide brown dwarf — a substellar object with a mass below the roughly 0.08 solar-mass threshold needed to sustain ordinary hydrogen fusion, resolving a decade of unconfirmed brown-dwarf candidates. It was identified using the Spanish Nordic Optical Telescope.

Teide 1, found in the Pleiades cluster, was confirmed in 1995 as the first bona fide brown dwarf — a substellar object with a mass below the roughly 0.08 solar-mass threshold needed to sustain ordinary hydrogen fusion, resolving a decade of unconfirmed brown-dwarf candidates. It was identified using the Spanish Nordic Optical Telescope.
The year a substellar object was first confirmed to be a genuine brown dwarf (too massive to be a planet, too low-mass to sustain hydrogen fusion).
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
