Astronomers discover red dwarfs absorbing matter from Earth-like planets

By observing various regions of the universe, astronomers sometimes find surprising phenomena. Indeed, after discovering a collision between two neutron stars and an exoplanet with a potential atmosphere, they have detected red dwarfs absorbing matter from Earth-like planets.

This discovery was revealed in a new study published in the Monthly Notices of the Royal Astronomical Society. Several researchers from Keele University and the University of Exeter have studied thousands of stars and discovered six red dwarfs exhibiting unusual behavior.

After conducting various observations, they noticed that these stars contained lithium. However, this chemical element should not be present in these celestial objects, as explained by Professor Robin Jeffries of Keele University, and lead author of the study:

"Red dwarfs are smaller and cooler than our Sun but inside they are extremely hot. This heat should destroy all of their fragile lithium in nuclear reactions shortly after they form."

Therefore, according to astronomers, these stars, which are the most common in the universe, could have absorbed matter from Earth-like planets. Thus, while this discovery highlights the destructive behavior of red dwarfs, it could also help researchers understand how planetary systems form. However, further studies will need to be conducted in the future using new instruments to identify stars with the same behavior.
