Sentences with phrase «star radiation pressure»

Not exact matches

Incrementally adjusting its angle as it approaches to soak up more radiation pressure from the stars, that sail could bleed off enough speed to be captured into orbit within the system.

But the twin stars» radiation pressure has its limits; if Heller's and Hippke's 100,000 - square - mter light sail came in any faster than 4.6 percent light - speed, it would simply overshoot the system.

As far - off as that is, the timing could be much worse, Heller says: Sending their sail directly to Proxima Centauri would demand much slower interstellar speeds due to the smaller star's weaker radiation pressure and braking ability, raising the total travel time to nearly a millennium.

The massive star Sirius, for example, is just over twice as far away as Alpha Centauri — but because it shines some 25 times brighter than our sun, it offers a stronger radiation - pressure braking effect, allowing light sails to approach at much higher speeds.

In this process, massive stars formed early in the life of a galaxy shine so brightly that the pressure of their radiation pushes lots of gas and dust out of the galaxy altogether.

Having a mass of only less than seven per cent of the mass of the Sun, they are unable to create sufficient pressure and heat in their interiors to ignite hydrogen - to - helium fusion, a fundamental physical mechanism by which stars generate radiation.

The collapse creates so much heat and pressure that the star forges the heaviest elements known and blasts them and most of its outer layers back out into space, along with blinding radiation.

Now, Hippke and Heller show that a combination of the stars» gravity and radiation pressure from their photons can bring the craft into a stable orbit around one of the stars, then around the tantalising planet (Astrophysical Journal Letters, doi.org/bx8t).

Ehrenreich and his team think that such a huge cloud of gas can exist around this planet because the cloud is not rapidly heated and swept away by the radiation pressure from the relatively cool red dwarf star.

With the inclusion of radiation pressure, the 2017 models show how these two factors can create spirals like those also observed around the same star.

We propose to use the radiation pressure of the star's light to slow down the probe, symmetrically to its initial acceleration using laser light.

In addition to the radiation pressure, the winds that so massive a star generates disperse its natal cloud, further limiting its growth as well as interfering with the formation of nearby stars.»

Is star formation triggered mainly by shockwaves from exploding stars, or the pressure created by radiation and stellar winds from massive stars — or can those processes get in the way of the collapse?
