The death of a star does not necessarily spell the end for most of the planets around it. An international team of scientists has found a planetary system that allows a glimpse of the future of the Solar System after the death of the Sun, according to a statement published by the Superior Council of Scientific Investigations (CSIC).
The WM Keck Observatory demonstrated through high resolution images shows how the closest planets to the dying star, like the earth, they will be destroyed, but not the furthest. The graphical representation shows how a solar system consisting of a white dwarf and a recently found Jupiter-like planet can give clues to what will be the moments when the Sun dies and becomes a red giant.
In this system, the white dwarf contains 60% of the mass of the Sun and the planet around it is 40% larger than Jupiter. The planet revolves around the star in a wide orbit, at a minimum distance of about three times that between the Earth and the Sun.
When a star dies, the first thing that happens is an accelerated expansion of it, turning it into a red giant and then it will continue to lose mass and energy until it becomes a white dwarf, a celestial body. much smaller than a star in his youth and much colder.
“This finding confirms that planets orbiting at a sufficiently great distance can continue to exist after the death of their star since this system is an analog to our own Solar System, suggests that Jupiter and Saturn could survive the Sun’s red giant phaseJoshua Blackman, a researcher at the University of Tasmania, who is leading the study, says in the statement.
“Given that 97% of the stars in our galaxy will become white dwarfs, this discovery and those that follow nthey will allow you to glimpse the future of exoplanets“, Indicates Camilla Danielski, IAA-CSIC researcher.
The research team plans to include their results in a statistical study to find out how many other white dwarfs have intact planetary survivors.
