Definition of collapsar in English: collapsarnounkəˈlapsɑːkəˈlapˌsär Astronomy An old star that has collapsed under its own gravity to form a white dwarf, neutron star, or black hole. Example sentencesExamples - In collapsars the accretion flow toward the black hole has been studied in detail by Popham et al..
- Two papers scheduled for an upcoming Astrophysical Journal Letters appear to support the collapsar model.
- A key feature of the collapsar winds is that they are capable of producing radioactive elements necessary to power a long-duration supernova light curve.
- Pruet and his colleagues are also investigating whether collapsars might be the sources of other elements as well.
- Still, the collapsar is an extremely attractive model that fits a wide range of observed gamma-ray bursts.
Origin 1970s: from collapse, on the pattern of words such as pulsar.
