Or it may have formed a bigger, spinning neutron star that, propped up by its own rapid rotation, existed for a few milliseconds — or potentially much longer — before collapsing.
Volker Bromm, a theoretical astrophysicist at the University of Texas, Austin, says rapid rotation «could also lead to a special class of energetic supernova explosions called hypernovae, with unusual chemical abundance patterns.»
In addition to variations in chemical composition — both because of the initial abundances and the star's evolutionary status, [34] interaction with a close companion, [35] rapid rotation, [36] or a magnetic field can also change a main sequence star's position slightly on the HR diagram, to name just a few factors.
Some of the newly formed ones have been detected because their rapid rotation sends radio pulses our way multiple times per second.

«It is the rapid rotation that creates a different and very strong magnetic field.
The rapid rotation created by mass transfer between the two stars appears necessary to generate the ultra-strong magnetic field and then a second mass transfer phase allows the magnetar - to - be to slim down sufficiently so that it does not collapse into a black hole at the moment of its death.
This rapid rotation appears to be the essential ingredient in the formation of the magnetar's ultra-strong magnetic field.
RAPID ROTATION A robot made entirely of DNA can rotate its arm (purple) 360 degrees or lock it down in certain positions thanks to special latches (yellow) on the bot's platform.
Astronomers recently discovered that it is the flattest star known, measuring more than 50 percent wider across the equator than from pole to pole; rapid rotation is responsible.

The researchers used a table built on air bearings that can spin at 120 revolutions per minute and support a load of up to 1,000 kilograms (about 2,200 pounds), meaning that it could spin a large tank of fluid at high speed in a way that mimics Jupiter's rapid rotation.
The challenge to re-creating swirling winds in the lab was building a model of a planet with three key attributes believed to be necessary for jets to form: rapid rotation, turbulence and a «curvature effect» that mimics the spherical shape of a planet.
The rapid rotation regime is defined by the Rossby deformation radius being less than planetary radius, which occurs for planets with rotation rate < 5 days.
