A recent theory claimed that stars might have appeared as a result of cosmic cannibalism.
Stars are known to have been born in a swirling cloud of interstellar gas and dust that contracts to star’s density due to its own gravitational force. The cloud goes into a circumstellar disk that is created around the star and afterwards lands on the star. The material carried through the disk onto the star leads to an increased mass of the star.
This phenomenon has currently became an important topic for research among astrophysicists. It was thought that stars accumulate their mass steadily but now experts no longer think this is true. They claim a sequence of violent actions which appear as sharp stellar brightening may be linked to the stars’ increased mass.
For example, in the Orion constellation, FU Orion’s star brightness was higher with a 250 factor in just one year. One possible theory for these brightening processes was revealed by Eduard Vorobyov 10 years ago. At the moment Vorobyov is working at the Astrophysical Department of the Vienna University with Shantanu Basu from the University of Western Ontario, Canada.
New data made them think the increase in stellar brightening may appear due to the gravitational processes of the star’s surrounding disk that leads to fragmentation. The experts compared the phenomenon to the action of throwing logs into a fireplace; they believe some excess of energy is released which eventually makes the star brighter. Moreover, they said the star consumes a massive amount of mass every ten days.
Eduard Vorobyov’s opinion is that the mass formation in the star’s disk followed by their transition on the star is a process of cannibalism on cosmic scales. Also, the researcher believes the clumps might have transformed into massive planets such as Jupiter if they hadn’t been swallowed by the star.
What’s more, this process is thought to resemble the Greek mythology. Kronos, the titan god ate his children except Zeus who threw him in Tartarus. Scientists claim this is a
“major step towards our understanding of how stars and planets form and evolve”.
Moreover, if their theory proves to be true, it would mean that even the Sun may be connected to these phenomena. This implies that large planets in the Solar system may actually be seen as survivors of the Sun’s tempestuous past. The theory that Stars might have appeared as a result of cosmic cannibalism gives a new perspective to all the experts in this field.
