Teide 1 is abrown dwarf located around 430 light years away in thePleiades. It was the first brown dwarf to be confirmed. Its surfacetemperature is 2,600 ± 150 K,[6] which is about half that of theSun. Itsluminosity is 0.08–0.05% of that of the Sun.[7] It is estimated to have about the same age as Pleiades, giving a plausible range from 70 to 140 Myr.[7]
Teide 1 was detected byRafael Rebolo López, María R. Zapatero-Osorio and Eduardo L. Martín in optical images obtained in January 1994 with the 0.80 meter diameter telescope (IAC-80) from theInstituto de Astrofísica de Canarias, located at theTeide Observatory on the island ofTenerife. Its cold nature was confirmed in December 1994 with theWilliam Herschel telescope (WHT) of the Roque de los Muchachos observatory inLa Palma. On May 22, 1995, the article reporting their discovery was submitted to the journal Nature, which published it on September 14, 1995.[8] Meanwhile, a similar object, Calar 3, was discovered. The brown dwarf nature of Teide 1 and Calar 3 was independently confirmed in 1996 following spectroscopic observations with the 10-meter diameter telescope of the W. M. Keck observatory of Mauna Kea on the island of Hawaii.[7]
