The sun swallows the planets close to it, including the earth – Mehr news agency RCO News Agency

According to Mehr news agency, quoted from InterestingEngineeringstars like the Sun consume hydrogen, expand and cool, and thus become red giants. In this regard, it is predicted that this dramatic change will occur for the sun in about five billion years. Researchers believe such an expansion could destroy Mercury, Venus, and possibly Earth, but so far there is little direct evidence to confirm exactly what happened.

Now a research led by university researchers Warwick and YossiL the eye size has provided a new version of the fate of stars orbiting dying stars. By analyzing about half a million near-Earth star systems, researchers are trying to understand how long planets survive after their host stars turn into red giants.

Their findings show that the existence of planets around stars that are in the final stages of their life is very limited. This suggests that many planets orbiting close to the star were probably destroyed as the stars grew larger. are. This provides strong evidence of planetary death.

According to University Astrophysicist Edward Bryant Warwick who led much of the research, the findings provide strong evidence that as stars evolve from the main sequence, they can rapidly cause nearby planets to spiral inward and annihilate.

This phenomenon has long been discussed in theory, but now its effect can be directly observed in a large population of stars. According to Bryant, aging stars can engulf nearby planets due to a gravitational phenomenon called tidal interaction. fashionswallow As the star expands, the planet’s pull on it causes the planet’s orbit to slow down. As a result, the planet enters an inner spiral to disintegrate or be absorbed.

The researchers focused on stars that recently entered the post-main sequence phase areconsumed all the hydrogen and identified about 130 planets and planet candidates orbiting them. 33 of them had not been traced before.

Focusing on stars that had cooled and expanded into red giants, they found that the probability of a planet near such a star was only 0.11 percent.
