Philoprogenitive STARS: PEACE YOUTH OF THE WORLD

Are there times that the star of ...

According to modern ideas, it all starts with a sparse cold clouds, which under its own gravity starts to shrink. Gradually, its density increases, especially in the central part. The energy of gravity is converted into heat and heats up the cloud - until finally the temperature at its core does not reach millions of degrees.

After that, start thermonuclear reactions, and the compression stops: pressure created by them, counteracts gravity. The rest of the cloud continues to revolve around a young star by condensing more pressure it emitted radiation and particles. In the end, the planet is born.

But the star attraction is too great, and the young planets continue to move closer to her still scattered gas-dust cloud, curled into a disk. Their rate of rotation of the orbit is not enough to effectively counter the centrifugal force of gravity. Theoretically, sooner or later the world should fall on the star - which, as we know from practice, there is at least not always.

Plevchen Peter (Peter Plavchan) Bilinsky and Christopher (Christopher Bilinski) interested in the question of what exactly stops the planets in their migration to the star. They conducted computer simulations based on data on 126- ty of the observed exoplanets reliably obtained ground-based telescopes, as well as 649- ty has not yet definitively confirmed extrasolar planets found by Kepler space probe.

The calculation showed that the migration stops void.... The fact that the accretion disk of gas near the star, a region of more white space, from which the substance is either absorbed by the star, or ... Friction, slowing the flight of the planet when it is here, drops, and the planet can better resist the attraction of the stars. The scientists conclude that ...
