Editing Tidal locking (section)

===Stars===
Close [[binary star]]s throughout the universe are expected to be tidally locked with each other, and [[extrasolar planet]]s that have been found to orbit their primaries extremely closely are also thought to be tidally locked to them. An unusual example, confirmed by [[MOST (satellite)|MOST]], may be [[Tau Boötis]], a star that is probably tidally locked by its planet [[Tau Boötis b]].<ref name="space.com">{{cite web |url=http://www.space.com/scienceastronomy/050523_star_tide.html |title=Role Reversal: Planet Controls a Star |date=2005-05-23 |first=Michael |last=Schirber |publisher=space.com |access-date=2018-04-21 |archive-date=2008-08-04 |archive-url=https://web.archive.org/web/20080804180104/http://www.space.com/scienceastronomy/050523_star_tide.html |url-status=live }}</ref> If so, the tidal locking is almost certainly mutual.<ref>{{cite journal | title=Life on a tidally-locked planet | last=Singal | first=Ashok K. | journal=Planex Newsletter | volume=4 | issue=2 | page=8 | date=May 2014 | bibcode=2014arXiv1405.1025S | arxiv=1405.1025 }}</ref><ref>{{cite journal | title=MOST detects variability on tau Bootis possibly induced by its planetary companion | url=http://www.aanda.org/articles/aa/full/2008/17/aa8952-07/aa8952-07.html | last1=Walker | first1=G.
