Everything has to wither away some day or the other. Likewise, it is interesting to know how the sun will look like when it will be in its last moments. Recent studies suggest that the sun will convert itself into a planetary nebula. It is believed to shed a large chunk of its mask and transform into the planetary nebula. The planetary nebula is a gigantic circular ring of the luminous gas. It will be towards the final stage of the sun’s life cycle.
The sun is a low mass star. The moment when it is about to wither away, it will turn into red giants and finally conclude into white dwarfs before extinguishing from the planetary system.
Additionally, as per the inputs suggested by a paper published in the Nature Astronomy, the sun will resemble a planetary nebula in between these two stages.
Earlier, the scientists doubted for the creation of the planetary nebula by the sun. The planetary nebula formation is the task of the stars who weighs double the mass of the Sun. The planetary nebula has been witnessed in more than ninety percent stars.
The computer model puts the illustration of the planetary nebula formation forward, which is a part of the published paper. It depicts that the hot cores of the stars heat up envelop. The heated envelope then expands at the rate of thirty kilometers per second. It is three times faster than the previous computer models. The entire phenomena occur when the temperature rises to forty thousand Kelvin.
It is expected that the low mass stars similar to the sun will give rise to the planetary nebulae, which will dazzle out to be visible before it withers away.
Ziljstra concludes, “We found that stars with mass less than 1.1 times the mass of the sun produce fainter nebula, and stars more massive than three solar masses brighter nebulae, but for the rest, the predicted brightness is very close to what had been observed. Problem solved, after 25 years!”
