hypermassive

From hyper- +‎ massive.

hypermassive (not comparable)

1. (chiefly astronomy) Extremely massive.

     “Wait a minute. Two years ago Johann Karlsen went down into a hypermassive sun, with a berserker-controlled ship on his tail. Unless that story’s not true?” “It’s perfectly true, except we think now that his launch went into orbit around the hypermass of falling into it.

   • 1968, Gérard de Vaucouleurs, Larousse Encyclopedia of Astronomy‎^[2], Paul Hamlyn, page 124:

     The old Population I stars, such as the Sun, would have been formed after this original distribution of the heavy elements. Once the hypermassive Population II stars had all disappeared, no further distribution of metals could occur. Population I supergiants would, however, continue to condense from the clouds of cosmic gas as long as any remained.

     He rode above a thunderstorm at war with a sunset— a ceaseless, soundless turmoil of fantastic clouds that filled half the sky like a nearby planet. But this cloud-mass was immeasurably bigger than any planet, vaster even than most giant stars. Its core and its cause was a hypermassive sun a billion times the weight of Sol.

     If the ejecta which will form spiral arms come from a temporarily hypermassive nucleus the necessary gravitational restraint can be applied to them. Such new physics, if valid, would have ramifications throughout astrophysics.

   • 1983, Isaac Asimov, Counting the Eons‎^[5], Doubleday, page 109:

     If one of these hypermassive exchange particles should happen to be transferred from one quark to another within a proton, a quark would be changed to a lepton, thus breaking both the law of conservation of baryon number and the law of conservation of lepton number. The proton, losing one of its quarks, becomes a positively charged meson that quickly decays into antielectrons, neutrinos, and photons.
