Contribution grade

Astrophysics · Source-reported experimental result or reusable measurement method

Reference score80,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Rebolo and colleagues reported a lithium absorption feature in spectra of the Pleiades objects Teide 1 and Calar 3. They combined the spectral feature with luminosity and evolutionary models to support the interpretation that these objects are brown dwarfs.

Scientific scope

Rebolo and colleagues reported a lithium absorption feature in spectra of the Pleiades objects Teide 1 and Calar 3. They combined the spectral feature with luminosity and evolutionary models to support the interpretation that these objects are brown dwarfs. The lithium feature overlaps molecular bands at the available resolution, and inferred masses depend on the atmospheric models, temperature calibration and assumed cluster age. The earlier object discovery and lithium-test proposals are separate contributions.

Evidence

The linked original works support the scoped statement and contribution attribution. WRS has not independently replayed experiments or reconstructed a full mathematical proof. The lithium feature overlaps molecular bands at the available resolution, and inferred masses depend on the atmospheric models, temperature calibration and assumed cluster age. The earlier object discovery and lithium-test proposals are separate contributions.
