Sentences with phrase «outer layers of the star»

This causes a shock wave which blasts its way out through the infalling material, colliding with outer layers of the star as it does so.
The X-rays shown in red are from the supernova material itself - the outer layers of the star expanding outward behind the shock wave.
«Jets of material then hit the expanding outer layers of the star to produce the gamma - ray emission.»
When one star collapses, the resulting black hole and the other star wind up swirling through a «common envelope» of gas — literally the outer layer of the star.
Those time spans coincide with known stellar behavior: once a year, for example, a red giant pulsates in brightness, an event astronomers think is linked to an episodic shedding of gas; likewise, every 5,000 years the helium in an outer layer of the star ignites and burns up in a flash, and the star undergoes a brief burst of expansion.
The outer layers of the star — the stellar «atmosphere» — absorb this excess and swell outward into the characteristic distended figure of a red giant.
Meanwhile, much of the material that once made up the outer layers of the star is released into the surrounding area, and may form something called a planetary nebula (which, despite the name, doesn't actually have anything to do with planets).
When stars exhaust their hydrogen fuel the outer layers of the star can expand greatly and the star becomes a giant.
The spectacular structure of the planetary nebula contains the outer layers of a star that were expelled into interstellar space.
When the helium ignites, the outer layers of the star are blown off in huge clouds of gas and dust known as planetary nebulae.
The outer layers of the star are blown off into space, and are often seen as an expanding remnant shell of hot gas.
The colorful network of filaments is the material from the outer layers of the star that was expelled during the explosion.
This little nebula, like NGC 3242 above, is the remains of the outer layers of a star, not unlike our Sun.
The outer layers of the star are then expelled from the super-hot core, resulting in a stellar body that is hundreds of times its original size.
The outer layers of the star fall inward on the neutron core, thereby crushing it further.
Since gamma radiation provides the energy preventing gravitational collapse of the outer layers of the star onto the core, at some point the loss of this energy (through so - called «pair instability») causes violent pulsations that eject a large fraction of the outer layers of the star and eventually a star's outer layers to collapse inward to create a thermonuclear explosion that, in theory, would be brighter than previously detected supernova.
The increasingly hot core also pushes the outer layers of the star outward, causing them to expand and cool, and transforming the star into a red giant.
The outer layers of the star also begin collapsing; however, because of the enormity of the release of energy, they rebound and are shot out into space.
