Scientists have discovered a star in the main sequence swallowing the planet. Reported by Universe Today.

Initially, scientists drew attention to this star when they recorded the optical transition of the intermediate luminosity ZTF SLRN-2020. This is what experts call an astrophysical phenomenon in which a star shines brighter than a new star, but much weaker than a supernova. These events are relatively rare to see, and scientists know very little about them. According to one version, they are caused by the absorption of the planet. One key difference between the star that gave birth to ZTF SLRN-2020 was that it was located in the main sequence – that is, it was relatively old, while in young stars the planets can orbit in a chaotic manner and fall regularly. star.

Now astronomer Noam Socker analyzed reconstructed past observations and swallowing. He concluded that the planet did not “dive” into the photosphere and disappeared, but instead underwent a series of transformations. As it got closer to the star, the planet warmed and its outer layers turned into plasma. This gave rise to a series of electrical and magnetic phenomena, as a result of which jets (jets) began to eject from the planet. However, the velocity of the material of these jets was not great enough to overcome the attraction of the star, and so it fell on it.

Prior to final absorption, an accretion disk may form from the planet’s material around the star, which slowly flows over it. During all the interactions described above, huge amounts of energy recorded by astronomers were released.

Formerly paleontologists saidwhere live “bagels” live obama 550 million years old.
