Neutron stars are the collapsed cores of supergiant stars. [1] They are created as a result of supernovas and gravitational collapse, [2] and are the second-smallest and densest class of stellar objects. [3] In the cores of these stars, protons and electrons combine to form neutrons. [2] Neutron stars can be classified as pulsars if they are ...

Comparison of a 10 km radius neutron star (top left corner) and a 6000 km radius white dwarf, the latter roughly the size of Earth. Neutron stars have overall densities of 3.7 × 10 17 to 5.9 × 10 17 kg/m 3 (2.6 × 10 14 to 4.1 × 10 14 times the density of the Sun), [a] which is comparable to the approximate density of an atomic nucleus of 3 ...
Neutron star: Neutron stars are stellar remnants produced when a star of around 8–9 solar masses or more explodes in a supernova at the end of its life. They are usually produced by stars of less than 20 solar masses, although a more massive star may produce a neutron star in certain cases. [2] 4U 1820-30: 9.1 Pulsar [3] Lich Pulsar (PSR ...

In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
Stars that are at least sometimes visible to the unaided eye have their apparent magnitude (6.5 or brighter) highlighted in blue. The first list gives stars that are estimated to be 60 M ☉ or larger; the majority of which are shown. The second list includes some notable stars which are below 60 M ☉ for the purpose of comparison. The method ...
