The hunt for exoplanets, planets located outside our solar system, which is very active in the last decade, has already produced a lot of results, which led to some incredible discoveries
And now, planetary scientists have a new scientific instrument — a detailed mathematical model that describes in detail the processes that lead to the birth of new planets.
According to this model, the cloud of gas and dust form a sufficiently dense disk around the central star. Millions of years, micro-and particulate matter that disk collide and form larger objects, which gradually increase the weight and getting bigger. And, in the end, some of these objects are obtained by the planet.
The mathematical model describing the formation of gas and dust disk around the star and the processes occurring inside the disc, was developed by a team of scientists from the University of Texas at Austin (University of Texas at Austin), led by Sally Dodson-Robinson (Sally Dodson-Robinson). The mathematical model is so complex that it requires for its calculation power supercomputer Ranger, located in the data center Texas Advanced Computing Center (TACC).
Scientists, using their mathematical model, conducted a series of calculations with different sets of input data. Thus they were able to find conditions under which there was the formation of planets in our solar system, which to some extent confirms the efficiency of the mathematical model is not a bad idea, and algorithms.
Well, the video below you can see the visualization of the calculation of the mathematical model of the formation of new planets.
