Molekyylivalkio

Molekyylivalkio is a Finnish term that translates to "molecular star" or "molecular giant". It refers to a type of star that is still in the process of forming. Specifically, it is a dense cloud of gas and dust that has begun to collapse under its own gravity. As the cloud collapses, its temperature and density increase, and it starts to emit radiation. This radiation is primarily in the infrared part of the spectrum, which is why these objects are often detected by infrared telescopes.

Molekyylivalkiot are a crucial stage in the birth of stars. They are the precursors to protostars, which are stars that have begun nuclear fusion in their core. The material within a molekyylivalkio continues to accrete onto the central protostar, providing it with the mass needed to eventually become a stable, main-sequence star. The study of molekyylivalkiot helps astronomers understand the complex processes involved in stellar formation and the early evolution of planetary systems. These massive clouds are composed mainly of molecular hydrogen, but also contain helium and trace amounts of other molecules, including water and carbon monoxide. The exact conditions and timescale for the formation of a molekyylivalkio and its subsequent evolution into a protostar depend on the initial mass and density of the gas cloud.
