Scientists get gruesome look at how stars like our sun eat their own planets

Scientists have known for a long time that one day the sun will grow into a red giant and destroy its nearest planets. The study explores how devoured planets can affect the processes inside the dying star.

Red giants that are ten times larger than the original star are created when the size of the sun runs out. There are a lot of things that can happen when the red giants surround the planets.

A new study claims that expelling large planets, defined as 10 or more times the size of Jupiter, can cause the star to shed its envelope and increase its brightness.

Scientists find mini red giant stars.

A glimpse into the possible future scenarios of our own solar system's evolution was provided by the study. To gain in-depth insights into the interactions between stars and planets, the researchers had to model only a small portion of the boundary.

"Evolved stars can be hundreds or even thousands of times larger than their planets and this disparity of scales makes it difficult to perform simulations that accurately model the physical processes occurring at each scale." We used a small section of the star centered on the planet to measure the drag forces acting on it.

The results may provide a glimpse into what will happen 5 billion years from now when our sun turns into a red giant, as well as explain the discovery of planets around white dwarfs.

Some planets may be able to survive being burned by the red giants.

Mercury and Venus are the closest planets to the sun in our solar system. Earth will be so scorched that it will be impossible to live on. Jupiter, Saturn and their moons may have more life-friendly conditions in the vicinity of the sun.

Researchers believe that further studies of exoplanets will lead to more discoveries since only a few planets that have survived a red giant engulfment have been observed so far.

Yarza believes thatplanetary engulfment is common.

The study can be found in the online repository arxiv, which was published in the Astrophysical Journal.
