Lithium is also found in [[brown dwarf]] substellar objects and certain anomalous orangemetal-poor stars. Because lithium is present in cooler, less massive brown dwarfs, but is destroyed in hotter [[red dwarf]] stars, its presence in the stars' spectra can be used in the "lithium test" to differentiate the two, as both are smaller than the Sun.<ref name=emsley/><ref name="Cain"/><ref>{{cite web|url=http://www-int.stsci.edu/~inr/ldwarf3.html |archive-url=https://archive.today/20130521055905/http://www-int.stsci.edu/~inr/ldwarf3.html |url-status=dead |archive-date=21 May 2013 |title=L Dwarf Classification|accessdate=6 March 2013 | first =N. | last = Reid | date = 10 March 2002}}</ref>
