Word	Definition
remnantsnoun	A small portion remaining of a larger thing or group; part of a former whole.
hypernovanoun	(astronomy) The gravitational collapse of a massive star to form a black hole.
failed supernovanoun	(astronomy, astronomy) An event that ends the fusion lifetime of a large and massive star. It is a partial type-II supernova, where the collapse process occurs, but no significant rebound occurs, and the nascent black hole swallows the incoming implosion resulting in no outbound explosion or subsequent light burst.
neutron starnoun	(astronomy) A degenerate star that has been so collapsed by gravity that its electrons and protons have been merged into neutrons by the intense pressure. The solid mass of neutrons is sometimes called neutronium.
supernova impostornoun	(astronomy) An extremely energetic stellar flare event that is bright enough to be mistaken for a supernova, but through later spectral analysis is revealed to not be one.
bosenovanoun	(physics) A very small, supernova-like explosion, which can be induced in a Bose-Einstein condensate by suitably changing its magnetic field.
neutronizationnoun	(physics, astronomy) The process, such as within a collapsing star, in which protons and electrons fuse to form neutrons and release neutrinos.
gravitational collapsenoun	The stage in the evolution of a star in which the pressure of the star is insufficient to maintain it at a stable size, and its material falls inward under its own gravity, eventually forming a black hole or a neutron star, and sometimes accompanied by a supernova explosion.
kilonovanoun	(astronomy) A type of supernova that is underluminous, caused by the merger of two neutron stars
runaway starnoun	(astronomy) A star that has a high velocity relative to its surroundings (typically the result of a supernova in a binary star system).
emission nebulanoun	(astronomy) A nebula composed of ionized gases which produce visible light (as distinct from a reflection nebula, which reflects the light produced by neighboring stars).
neutron emissionnoun	(nuclear physics) A nuclear reaction in which one or more neutrons are emitted.
neutrinospherenoun	(astronomy) The region of a star or supernova rich in neutrinos.
jet cocoonnoun	(supernovae astronomy) A cloud of gas that obscures the poles of a star undergoing hypernova (HN), which gets heated by the polar jet escaping the hypernova progenitor star (hnp), and may absorb the energy of a weak gamma-ray burst (GRB), leaving an observable HN lacking the associated GRB, or be penetrated by a stronger GRB, giving a HN with an associated GRB.
protostarnoun	(astronomy) A collection of gas and dust in space with high temperature that usually grows to the point of beginning nuclear fusion and becoming a star.
superwindnoun	(astronomy) An outflow of highly energetic radiation and material from a starburst galaxy.
big bangnoun	(cosmology) The cosmic event that marks the beginning of time and the rapid expansion of space for the visible universe. The evolution of the universe since that beginning point is described by the Big Bang Theory.
dwarf novanoun	(astronomy) A cataclysmic variable star consisting of a close binary star system in which one of the components is a white dwarf that accretes matter from its companion.
white nebulanoun	(astronomy, obsolete) a nebula that appears white in colouration through a high-powered telescope (nebulae often appear to have some hint of colour through a powerful telescope, but white when not using a powerful instrument); these nebulae were generally to be determined to be galaxies in the 20th century
dark starnoun	(astronomy, physics) An extremely bright and massive hypothetical astrophysical object whose illumination is powered by annihilation of dark-matter particles and anti-particles (or by self-annihilation if they are Majorana particles).
