Found via reverse dictionary — words that share a conceptual meaning.
| Word | Definition |
|---|---|
| supernovanoun | (astronomy) A powerful and bright explosion of a massive star, which afterwards becomes a neutron star or a black hole, or is destroyed. |
| 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. |
| 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. |
| black hole starnoun | (astronomy, cosmology) A theoretical early universe object, with the outer layers of a star and a black hole for a stellar core. Theorized to be born of an ultramassive pre-stellar nebula collapse to an ultramassive protostar, and later birthing an intermediate mass black hole when the star's life ends. |
| kilonovanoun | (astronomy) A type of supernova that is underluminous, caused by the merger of two neutron stars |
| 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. |
| 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. |
| 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. |
| neutronizationnoun | (physics, astronomy) The process, such as within a collapsing star, in which protons and electrons fuse to form neutrons and release neutrinos. |
| frozen starnoun | (astrophysics) Synonym of stellar black hole. |
| 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). |
| 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. |
| quasistarnoun | (astronomy, cosmology) A theoretical early universe object, with the outer layers of a star and a black hole for a stellar core. Theorized to be born of an ultramassive pre-stellar nebula collapse to an ultramassive protostar, and later birthing an intermediate mass black hole when the star's life ends. |
| hypernuclidenoun | (physics) A hyperonic nuclide |
| bosenovanoun | (physics) A very small, supernova-like explosion, which can be induced in a Bose-Einstein condensate by suitably changing its magnetic field. |
| microquasarnoun | (astronomy, stars) A high-energy binary star system that includes black hole or neutron star and which resembles a quasar. |
| infallnoun | (countable) The area where water, storm runoff, etc., enters a storm drain. |
| blazarnoun | (astronomy) A very compact quasar, associated with a supermassive black hole at the center of an active galaxy. |
| quasi-starnoun | Alternative form of quasistar. [(astronomy, cosmology) A theoretical early universe object, with the outer layers of a star and a black hole for a stellar core. Theorized to be born of an ultramassive pre-stellar nebula collapse to an ultramassive protostar, and later birthing an intermediate mass black hole when the star's life ends.] |
| 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). |
