Detects aluminum around a new star thanks to the ALMA telescope

The trace of aluminum has been found in meteorites considered one of the longest solid objects in the Solar System , but so far the scientific world has yet to relate to the process of formation and evolution of they are with the formation processes of planets and stars.

In a conclusion quoted in the Astrophysical Journal Lettersel , the research team works at ALMA, asserting 'this finding is therefore a great opportunity to study the process. Initial formation of meteorites and planets like Earth '.

This text explains that the stars are surrounded by gas disks, and some of them will "solidify" and shape cosmic dust particles that will eventually coalesce to form larger objects, from meteors, to planets and eventually to planets. Understanding this initial formation of solid objects is a fundamental step in understanding the whole process later.

Prof Shogo Tachibana, of the University of Tokyo and the Japan Space Exploration Agency (JAXA), and colleagues analyzed data collected through the telescope at ALMA about the giant star with the symbol Orion KL Source I and detects the characteristic emission of aluminum oxide molecules .

Professor Tachibana said: 'Aluminum oxide plays a very important role in forming the most ancient matter of the Solar System. Our findings will help to understand the evolution of matter in the beginning of the Solar System '.

According to the plan, the team will look at other young stars to find the presence of aluminum oxide. Combining these observations with data from meteorites and specimens from JAXA's Hayabusa 2 missions, Professor Tachinaba believed he would get basic information about the picture. city ​​and evolution of the Solar System and other planetary systems.
