A new study has confirmed that a quarter of our Sun-like stars have swallowed their planets at some point within the solar system.
According to new research, these “cosmic crimes” perpetrated by stars against their relatives from neighboring planets are destructive to many planetary systems, resulting in disruption of the solar system.
According to new research published in Natural astronomy, “Evidence of observation. Systems The planets may have been very different from each other and their dynamic histories may have been very different, perhaps as a result of the extreme sensitivity of the initial stages in which they arose. Perhaps these dynamic processes in the most chaotic systems can disrupt the orbits of the planets and cause them to be swallowed up by their stars. ”
The study considers these indicators to be “solid evidence of phenomena sinking the planet by stars such as our Sun.”
The Sun is a very rare star in the Milky Way because it belongs to a certain class
In turn, the press noted Science “science”, which touched on research, That our sun is a rare star in the Milky Way. Most of the stars in our galaxy, about 75%, are M-type stars or “red dwarfs”, which are small, cold and long-lived stars. As for our sun, it is a type (G) star or “yellow dwarf”; The Milky Way contains only 7% of G-type stars.
Not only that, but astronomers believe that most stars are born out of stellar systems that contain one or more siblings (i.e., a group of two or three stars). Most stars in the Milky Way have at least one mate, i.e., unlike our Sun, two stars are imprisoned in alternating orbits as a dual system. The sun may have lost twins somewhere for a long time.
When a dense knot collapses A cloud of molecular gas floating in space Under the influence of its gravity and rotation, the formation of the primary star begins, but the primary star swells as gas accumulates around it, splitting its disk into pieces and into two or more pairs.
Once the stars are formed, the remnants of the orbit around them form planets, asteroid belts, comets, as well as all other objects that make up a planetary system, or a solar system like ours. .
But every rule has an exception … the stars swallow their planets
A team of astronomers led by Lorenzo Spina from the Astronomical Laboratory in Padua, Italy and the University of Monash in Australia decided to study binary systems. They identified 107 pairs of stars with similar surface temperatures and gravity and carefully studied their chemical properties. Scientists have increasingly observed double stars with “incompatible chemistry”.
There is such a thing as cosmic cannibalism.

“Although the stars in binary systems share the same type of chemistry, the 33 pairs of stellar elements in our model contain iron, which differ irregularly at the 2-sigma level,” the researchers wrote. This difference indicates that all stars, such as the Sun, have a 20-35% chance of swallowing their planets.
The researchers said that “as planetary matter enters the star and pollutes the tropics, the composition of the galaxy changes to reflect the composition found in the rock bodies of the planets, which are inert elements such as metals and silicate. More than turbulence.”
Scientists have concluded that stars that swallow their planets “must have a lot more refraction at turbulence than normal ratios found in stars of similar ages and metals”.
Scientific evidence suggests that this research provides further evidence that a large part of the systems around stars, such as the Sun, had a very turbulent beginning to life.
These disturbances, according to scientists, could have a significant impact on understanding how life evolved on Earth because all the stars in the study are binary. The results indicate that “binary systems are too confusing for the standard conditions necessary for the origin of the organism.”
A new “source” for the study of Earth-like planets
The researchers wrote:Possibility to detect chemical signals of planetary intake events Unlike our solar system, we can use the star’s chemical composition to predict whether its planetary system has passed through a complex dynamic past, which keeps its planets in almost circular orbits.
The researchers noted that these results may be “evidence” from which scientists are unlikely to hold Earth-like planets or identify sun-like stars that are the opposite.
Does the sun swallow the planet? … weird and confusing answers
According to an article published in the magazine ‘American science’ may have formed the thin outer layers of the sun The Earth moves inward toward the Sun, but on the other hand, scientists point to a completely different theory, some pointing out that the Sun expands outside the planet’s orbit, i.e. an astronomical unit (AU), but during its expansion it loses mass, and as a result the Earth moves outward, the force of gravity Decreases, but these are hypotheses that could occur billions of years later.
