How Sun-like Stars consume their own planets
Sun as Red -Giant
Study:
The the sun will eventually grow to the size of a red giant and swallow its neighboring planets, according to science. A recent study investigates the potential impact of these eaten planets on the dying star's internal procedures.
Red giants:
Red giants, which can grow to be more than ten times bigger than the initial star, form when sun-sized stars run out of hydrogen in their cores. All kinds of things can happen as these red giants swallow up the planets that surround them.
Research:
According to the latest research, swallowing massive planets, which are defined as planets ten times the size of Jupiter or larger, can cause the star to lose its protective envelope and brighten many orders of magnitude over millions of years.
Hydrodynamical Simulations:
The research, which used a technique called hydrodynamical simulations, offers a look into potential future prospects of the evolution of our own solar system. Red giant stars are enormous, thus to fully understand the connections, the researchers could only model a small fraction of the border between the stars and planets.
The lead author of the study, Ricardo Yarza, a graduate student in astronomy at the University of California,a student, said that" because evolved stars can be hundreds or even thousands of times larger than their planets", it is challenging to run simulations that accurately model the physical processes taking place at each scale.
"Instead, in order to comprehend the flow around the planet and calculate the drag forces operating on it, we mimic a small portion of the star that is focused on the planet."
Result:
The findings may explain recent discoveries of planets around white dwarfs, the burned-out stellar carcasses that stars evolve into during the red giant phase, as well as future events when our sun becomes a red giant in approximately five billion years.
Some planets may escape being burned by red giants, according to these studies that examine the latter phases of this planetary invagination.
Mercury and Venus, the two planets in our solar system nearest to the sun, are predicted to be completely absorbed by the expanding sun.
