Researchers have discovered a galaxy that can help study the different stages of evolution of a planetary system-Scientific Investigation-cnBeta.COM



Researchers have discovered a unique step in the evolution of planetary systems by imaging a star system more than 400 light years away.The project scientist said this discovery provides an opportunity to study how the solar system develops. What we found this time is the fast-flowing carbon monoxide gas flowing out of a young low-mass star.

Researchers believe that studying the unique stages of planetary system evolution can provide insight into how the solar system evolved. This discovery also shows that the development of the solar system could be more complex than previously thought. At present, it is unclear how the gas is emitted at such high speeds. Researchers led by Cambridge University believe that high-speed gas can be generated through icy comets that evaporate in the star’s asteroid belt.

The system was discovered in the investigation of young class III stars using Chile’s Atacama Large Millimeter / Submillimeter Array (ALMA). Some of the stars being studied are surrounded by debris disks, thought to have been formed by constant collisions of comets, asteroids and planets. These collisions occurred on the periphery of the newly formed planetary system.

The dust and debris remaining in these collisions absorbs the light from the central star and radiates this energy into a weak light, which can be studied with ALMA. The star studied by the researchers is called “NO Lup” and has a mass of about 70% of the sun. It has a low-mass, low-density dust disc, and is the only Class III star studied for carbon monoxide.

Detection of Class III star with carbon monoxide is a first for ALMA. Some scientists believe that when NO Lupon reaches the current stage of evolution, its planet will lose its original gas. Detection of carbon monoxide gas is very rare, but what makes the gas observed by ALMA so unique is that its scale and speed have prompted subsequent research. These subsequent studies show that this gas can be generated during collisions between asteroids, or during the high altitude of comets’ surface around stars that are thought to be rich in carbon monoxide ice, that is, the change of solid to gas.
