Sentences with phrase «outer gas»

As a second - ascent giant brightens, the star's outer gas layers become unstable, and it may begin to «valve» its outgoing radiative energy by pulsating which also changes its brightness.

While we have four inner rocky planets and four outer gas giants, many other systems have «hot Jupiters» very close to their star.

The swelling of the star's outer gas envelope also cools the surface, however, which makes the star look redder.

The star Kepler 36 has two planets: an inner rocky world slightly larger than Earth, and an outer gas giant about the size of Neptune.

But iPTF14hls maintained a toasty temperature — about 5,700 ° Celsius — for the entire time it was observed, and its outer gas layers did not slow down as they should have.

The gravity of the outer gas giants quickly drew these elements in, bloating them into their current forms: solid cores of rock and ice covered with gas.

H. Bond (STSci), R. Ciardullo (PSU), WFPC2, HST, NASA CM Draconis B is a white dwarf (a remnant stellar core which enriched its binary companions, Stars Aab, with elements heavier than hydrogen when it cast off its outer gas layers) like planetary nebula NGC 2440.

Eventually, Stars Aa and Ab will lose much of their current mass, from intensified stellar winds that eventually puff out their outer gas envelopes of hydrogen and helium (and lesser amounts of higher elements such as carbon and oxygen) into interstellar space as planetary nebulae.

Called «NASA's Leadership and America's Future in Space,» the report said that studying the outer gas giant planets (such as Saturn) help scientists learn about their atmospheres and internal structure.

Meanwhile, gases froze into giant balls that would build the outer gas giants.

Moreover, as a giant star swells, the temperature of its outer gas envelope falls, and so less light is produced there.

H. Bond (STSci), R. Ciardullo (PSU), WFPC2, HST, NASA (Sirius B is a young white dwarf, a remnant stellar core, which enriched Sirius A with elements heavier than hydrogen when it cast off its outer gas layers, like planetary nebula NGC 2440)

As a result of faster rotation and up - and - down convection in its outer gas layers, the star is probably also more magnetically active than our Sun.

Since the outer gas envelopes of the stars are in contact (overflowing their Roche lobes), they essentially share a common photosphere despite having two distinct nuclear - burning cores.

H. Bond (STSci), R. Ciardullo (PSU), WFPC2, HST, NASA — larger image (Gacrux may have a white dwarf companion B, a remnant stellar core that has already cast off its outer gas layers, like planetary nebula NGC 2440.)

H. Bond (STSci), R. Ciardullo (PSU), WFPC2, HST, NASA HD 147513 B is a young white dwarf (a remnant stellar core which enriched its binary companion, Star A) with elements heavier than hydrogen when it cast off its outer gas layers) like planetary nebula NGC 2440.

Such «barium stars» may be binaries, where a more massive companion has already thrown off its outer gas envelopes as a planetary nebula in becoming a white dwarf (see HD 147513 AB).

Eventually, the star will lose much of its current mass, from an intensified stellar wind that eventually puffs out its outer gas envelopes of hydrogen and helium (and lesser amounts of higher elements such as carbon and oxygen) into interstellar space as a planetary nebula.

And its outer gas layers did not slow down as they should have.

A key test of this hypothesis would be to ascertain whether carbon - based life ever arose in Earth - like habitats that may have once existed, or still persist, elsewhere in the Solar System — on Mars, on Venus, and in other planetary bodies (including sub-ice oceans on Europa and other large moons of the outer gas giants)-- as well as around other stars.

H. Bond (STSci), R. Ciardullo (PSU), WFPC2, HST, NASA — larger image (White dwarfs are remnant stellar cores that have cast off their outer gas layers, like planetary nebula NGC 2440)

As they die, these stars release their outer gas layers, leaving behind a dense core barely visible as a white dot of light in the center of the nebula.

Lowell figured that a new planet beyond Neptune would explain the discrepancies in the orbits of the outer gas giants.
