How Stars Form - Christopher McKee (SETI 2017)
Δημοσιεύτηκε στις 3 Φεβ 2017
Stars
are the atoms of the universe. The process by which stars form is at
the nexus of astrophysics since they are believed to be responsible for
the re-ionization of the universe, they created the heavy elements, they
play a central role in the formation and evolution of galaxies, and
their formation naturally leads to the formation of planets. Whereas
early work on star formation was based on the assumption that it is a
quiescent process, it is now believed that turbulence plays a dominant
role. In this overview, I shall discuss the evolution of our
understanding of how stars form and current ideas about the stellar
initial mass function, the rate of star formation, the formation of
massive stars, the role of magnetic fields, and the formation of the
first stars.
