description Teide 1 Overview
Teide 1 is a brown dwarf in the Pleiades open cluster, a group of stars in the constellation Taurus. Its identification was announced in 1995 and followed by spectroscopic confirmation, including detection of lithium, a sign of its substellar nature. Teide 1 is distinguished from ordinary stars by having insufficient mass for sustained hydrogen fusion, making it a reference object for research on substellar atmospheres and evolution.
help Teide 1 FAQ
Where is Teide 1 located?
Teide 1 is a brown dwarf in the Pleiades open cluster in the constellation Taurus. It is part of a young stellar environment rather than an isolated object near the Solar System.
Why was Teide 1 important when it was identified?
Its identification was announced in 1995, followed by spectroscopic evidence including lithium. That evidence helped establish Teide 1 as a substellar object rather than an ordinary low-mass star.
What does lithium reveal about Teide 1?
A young brown dwarf can retain lithium because it never becomes hot enough to destroy it through sustained stellar fusion. Lithium detection therefore supports the conclusion that Teide 1 lacks the mass of a normal hydrogen-burning star.
Is Teide 1 a normal star in the Pleiades?
No, it is a brown dwarf, meaning it is below the mass needed for sustained hydrogen fusion. Its 1995 confirmation made it an important example of a substellar object inside a well-studied star cluster.
