e/Fast Low-Ionization Emission Region

Information
has gloss	eng: Fast Low-Ionization Emission Regions (FLIERs) are volumes of gas with low ionization near the symmetry axis of many planetary nebulae. Their outflow speeds are significantly higher than the nebulae in which they are embedded, and their ionizations are much lower.
lexicalization	eng: Fast Low-Ionization Emission Region
instance of	(noun) a nebula that was once thought to be a star with its planets but is now thought to be a very hot star surrounded by an expanding envelope of ionized gases that emit a fluorescent glow because of intense radiation from the star planetary nebula
