Neutron stars are very small stars (Usually 30km in diameter) with an extremely high density of 1.4 to 2.16 solar masses. A neutron star is a very small and dense star made almost completely of neutrons.They are small stars with a radius of about 11–11.5 kilometres.They have a mass of about twice that of the Sun.They are the smallest and densest stars known to exist in the Universe. Depending on the mass at the start of its life, a supernova will leave behind either a neutron star or a black hole. Meaning of neutron star. Neutron stars synonyms, Neutron stars pronunciation, Neutron stars translation, English dictionary definition of Neutron stars. Neutron star Definition from Encyclopedia Dictionaries & Glossaries. Once the core of the star has completely burned to iron, energy production stops and the core rapidly collapses, squeezing electrons and protons together to form neutrons and neutrinos. English Wikipedia - The Free Encyclopedia. They are what is left of a huge star which exploded as a supernova.. A star burns into a hydrogen gas helium. The density of the star is like that of the nucleus of an atom. It's all in how stars live their lives. Information and translations of neutron star in the most comprehensive dictionary definitions resource on the web. neutron star - WordReference English dictionary, questions, discussion and forums. Neutron stars comprise one of the possible evolutionary end-points of high mass stars. Studies of these events enable unique insights into astrophysics, particles in the ultrarelativistic regime, the heavy element enrichment history through cosmic time, cosmology, … A neutron star is a type of stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Neutron stars are the smallest and densest stars known to exist and they are rotating extremely rapidly. So, how does a massive star go from being a shining object to a quivering, highly magnetic and dense neutron star? A neutron star may be as little as 15 km in diameter but so dense that a teaspoonful would weigh 10000000000000 newtons* on Earth. The most intense variety of neutron star is one that comes from a parent star that rotates very rapidly. Neutron star definition: A neutron star is a star that has collapsed under the weight of its own gravity. Neutron star mergers are the canonical multimessenger events: they have been observed through photons for half a century, gravitational waves since 2017, and are likely to be sources of neutrinos and cosmic rays. Neutron stars are the smallest and densest stars known to exist and they are rotating extremely rapidly.A neutron star is basically a giant atomic nucleus about 11 km in diameter made especially of neutrons. The density of the star is like that of the nucleus of an atom. Hyponyms . The neutron star is born from a supernova explosion. en A large fraction of the neutrons in a neutron star could turn into hyperons and merge into dibaryons during the early part of its collapse into a black hole. A neutron star is a type of compact star that can result from the gravitational collapse of a massive star after a supernova. Hypernyms ("neutron star" is a kind of...): star ((astronomy) a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior). A celestial object of very small radius (typically 18 miles/30 km) and very high density, composed predominantly of closely packed neutrons. Neutron stars have a prevalence of around 0.7% and are usually of spectral type D. Some of the closest neutron stars to Earth are RX J1856.5 – 3754, situated at around 400 light-years away, and PSR J0108-1431, located at around 424 light-years away from us. Neutron stars are mostly concentrated along the disk of the Milky Way. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. Hyponyms (each of the following is a kind of "neutron star"): pulsar (a degenerate neutron star; small and extremely dense; rotates very fast and emits regular pulses of polarized radiation) A neutron star is a really dense, compact ball of neutrons. A black hole is anything but empty space. Search neutron star and thousands of other words in English Cobuild dictionary from Reverso. Define supernova, supernova remnant, interstellar medium, and neutron star Explain the 'guest star' observed in 1054 Summarize how a white dwarf becomes a neutron star A neutron star is a super-compressed object left over when stars with a mass between 1.4 and about 3 times the mass of our Sun exhaust their nuclear fuel and collapse inwards. The escape velocity for a neutron star is approximately half the speed of light. NEUTRON STAR 'NEUTRON STAR' is a 11 letter phrase starting with N and ending with R Synonyms, crossword answers and other related words for NEUTRON STAR We hope that the following list of synonyms for the word neutron star will help you to finish your crossword today. A neutron star is the core of a red giant which is so compressed through the force of its own gravity that its protons and electrons have been squashed together and have finished up as neutrons*. In this lesson, you'll learn the definition and some of the characteristics of neutron stars and learn how scientists study them. magnetar; pulsar; Translations neutron star (plural neutron stars) A degenerate star that has been so collapsed by gravity that its electrons and protons have been merged into neutrons by the intense pressure. | Meaning, pronunciation, translations and examples A celestial object of very small radius (typically 30 km) and very high density, composed predominantly of closely packed neutrons. Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star is insufficiently massive to produce a black hole. Neutron star definition. All Free. Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star … A neutron star is basically a giant atomic nucleus about 11 km in diameter made especially of neutrons. A neutron star is the incredibly compact core that remains after a supernova event.. The Creation of Neutron Stars . Neutron Star as “Giant Nucleus” A neutron star is the collapsed core of a large star (usually of a red giant). The remnants of a star that collapsed under its own gravity after going supernova. Neutron stars are the fascinating remains of older stars. The neutron is a subatomic particle, symbol n or n 0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons. The neutron star is an exotic astronomical object whose existence was predicted by theory 35 years before one was actually discovered in 1968. A neutron star is the collapsed core of a large star (usually of a red giant). A neutron star is a very small and dense star made almost completely of neutrons.They are small stars with a radius of about 11–11.5 kilometres.They have a mass of about twice that of the Sun.They are the smallest and densest stars known to exist in the Universe. When all his fuel is exhausted, he becomes red gaint. The solid mass of neutrons is sometimes called neutronium. These stars also emit extremely powerful magnetic fields that could rip planets apart. Neutron star or black hole. When the core of a massive star undergoes gravitational collapse at the end of its life, protons and electrons are literally scrunched together, leaving behind one of nature's most wondrous creations: a neutron star.
