Sentences with phrase «because giant stars»

In fact, it would have been extremely difficult to detect this substellar object around a highly evolved star like Edasich, because giant stars often pulsate and produce radial velocity patterns similar to substellar companions.

He might have faced competition from teammate Madison Bumgarner, 10 - 4 and second in the NL with a 1.94 ERA, but Bumgarner won't pitch in the All - Star Game because he started on Sunday for the Giants.

That's because, since the All - Star break ended and the second half of the season began, the Giants have been one of the worst teams in the game.

Justin R. Crepp, Freimann Assistant Professor of Physics, was part of the team that discovered KELT - 4Ab, a so - called «hot Jupiter» because it is a gas giant that orbits extremely close to one of the stars in its solar system.

«This result is unique because it demonstrates that a giant planet can form so rapidly that the remnant gas and dust from which the young star formed, surrounding the system in a Frisbee - like disk, is still present,» said Lisa Prato of Lowell Observatory, co-leader of the young planet survey and a co-author on the paper.

This is because pockets of gas rich in heavy elements would be created if a comet in the outer regions of a solar system got vaporised by a dying star in its red giant phase or by the expanding planetary nebula that follows it (arxiv.org/abs/1001.4513).

Many planets outside the solar system are even more massive than Jupiter, and they orbit their Sun - like stars at an Earth - like distance, but these faraway super-Jupiters are effectively giant gas balls that can not support life because they lack solid surfaces.

Because their gravitational grip is weak, the gas could have been pushed out before many stars could form; a few giant stars may have blasted it out with their fierce heat and explosive deaths, for example.

This scenario naturally produces a planetary system just like our own: small, rocky planets with thin atmospheres close to the star, a Jupiter - like gas giant just beyond the snowline, and the other giants getting progressively smaller at greater distances because they move more slowly through their orbits and take longer to hoover up material.

This lower limit was intriguing because the outer edge of the hole is about as far from its star as the giant planets in our solar system are from the sun.

These giants are fainter than our star system simply because they contain fewer stars.

To make that transformation, the mass - gaining companion star could experience a giant eruption because of some instability related to the acquiring of matter from the newly formed Wolf - Rayet.

«We know that these showers are linked to the jets because they're found in filaments and tendrils that wrap around the jets or hug the edges of giant bubbles that the jets have inflated,» said Tremblay, «And they end up making a swirling «puddle» of star - forming gas around the central black hole.»

Previous observations looked at brighter, aging red giant stars, which are not as plentiful because they represent a brief episode in a star's lifetime.

That's because the radiation emitted from the central star heats the gases circling a gas giant's center and, over time, scatters them away from the nascent planet, the scientists say.

This is because their intense magnetic activity interferes with the light emitted by the star to a far greater extent than a potential giant planet, even in a close orbit.

«Red giants don't have accretion disks, but many most likely have companion stars, which presumably have lower masses because they are evolving more slowly.

Fusion is more efficient than fission, but even if we enclose the sun in a perfect Dyson sphere, we'll still never convert more than about 0.08 percent of the sun's mass to energy we can use, because once the sun has consumed about a tenth of its hydrogen fuel, it will end its lifetime as a normal star, expand into a red giant, and begin to die.

Because a star remains a red giant for approximately a billion years, it may be possible for life to arise on bodies in the outer solar system, which will be closer to the sun.

The internal structures of giant planets are much less well known than those of main - sequence stars because of uncertainties in the equation of state of degenerate gas, the composition (typically non-solar), the interaction with the magnetic field and, in the upper layers, the relative magnitudes of internal heat and energy deposited from the sun.

In particular, it has suggested that we should see few gas giants around low mass stars because the gas disk is expected to dissipate before the atmosphere collapse leading to a rapid accretion phase.

For example, the Spitzer infrared astronomers favour a two major arm model because red giant stars (which emit a lot of infrared) are largely confined to the Perseus and Centaurus arms, whereas radio astronomers tend to favour a four major arm model because radio telescopes can detect atomic hydrogen in all four arms.

This is not because they are unusually small, but instead comes from their smaller radii and lower luminosity as compared to the other main category of stars, the giant stars.

The pulsar's rotation is thought to slow because the neutron star's powerful magnetic field acts as a giant dynamo, emitting light, radio waves and other electromagnetic radiation as the star rotates.

Because of its great distance from Earth, HE 0107 - 5240 is roughly about ten thousand times fainter than the faintest stars that can be seen with the unaided eye, despite being a highly evolved and relatively luminous giant.

«We are focusing on these big gas giants that are heated to very high temperatures due to the close proximity of their stars simply because they are the easiest to study with the current technology,» Evans said.

The gravity, and hence the pressure, on the surface of a giant star is much lower than for a dwarf star because the radius of the giant is much greater than a dwarf of similar mass.

Perhaps we're only saying this because the only image we've seen of her was shot by Annie Leibovitz, but Laura Dern's new Star Wars heroine looks like she's adding a giant dose of fashion to the galaxy.

You want it because it's got a giant three - pointed star on the front.

Those at the show include the Bergamasco, a giant walking felted beast; the Berger Picard (Think star of Because of Winn - Dixie); and Cirnechi dell» Etna (like a miniature Pharaoh Hound); Coton de Tulear (just remember Coton and cotton).
