small about 0.7 solar mass. Others with different ideas of how neutrons interact, believe that the limiting mass is higher about 2.2 solar masses.
The crucial question now becomes: Are there any stars that leave remnant with more mass than the magic figure of three solar masses ? (The maximum mass of a neutron star is probably less than this, but I stick with the figure three because it is certain that no evolved star can have more mass than that and remain stable.)
(Ibidem. 60] A black hole is not shown because the star would have to be over 3M initially before it could become a black hole. Its final size would be similar to that of neutron star.

19. During the night of 23-24 February 1987, the Canadian astronomer. Ian
Shelton, working at the Las Companas Observatory in Chile, had the extraordinary good fortune to be the first professional' to discover a supernova (a night assistant had just noticed it with the naked eye as a 4th magnitude star). The Large Magellanic cloud, in which the supernova occurred, is an irregular galaxy.... A telegram was sent urgently to the Bureau of the International Astronomical union, and caused an immediate sensation in the astronomical community.

[Ibidem P. 110) 21. A 10 M spherical black nole has an area of 5650 square kilometres
comparable to the size of a country. Similarly the surface gravity is inversely proportional to the mass. A 10M, spherical black hole has a surface gravity 150 billion times that of the Earth.
[Ibidem P. 196] 22. A typical mini black hole of 10 grams, the size of a proton, has a temperature of trillion K.
