A new study suggests that the Sun will lose a large amount of its mass and will gradually turn to a planetary nebula, which will be a giant luminous cloud of gas as it will come to end of its cycle.
Professor Albert Zijlstra who hails from the University of Manchester’s School of Physics and Astronomy has joined a team of international astronomers who are researching the things that will happen with the sun when it will die in about 10 billion years from now.
The study which was done by them has shown that the sun will be turning to a planetary nebula which will get surrounded by ionized gas. The study was published on May 7th in the journal Nature Astronomy.
According to Albert Zijlstra, who is the co-author of the paper and a professor of astrophysics at the University of Manchester said, “When a star dies it ejects a mass of gas and dust – known as its envelope – into space. The envelope can be as much as half the star’s mass. This reveals the star’s core, which by this point in the star’s life is running out of fuel, eventually turning off and before finally dying.”
As per an old study, it suggested that the stars with smaller masses like the sun will be turning into nebulae which will be not bright as big stars are. This will result in invisible of this nebula from far away. During the early period, scientists were not sure about the mass of the Sun and that mass is good enough to create the envelope of material in planetary nebulae. This happens with 90 percent of all stars, but they have double the mass of the sun.
According to a computer model, which was described in a model of a paper, shows that the hot cores of the stars are involved in heating up the envelope, and it helps in expanding about 30 Kilometers per second. This is about three times faster than the previous models in a temperature of about 40,000 Kelvin.
This shows that the low mass stars like the sun can also create planetary nebulae which are bright enough to get visible from a distant place. According to the Penn State astronomer Robin Ciardullo, he said that this study is an important step towards the future.
