How can we use stellar kinematics to measure masses of stars? Any equations or reference papers to explain would be great!
The IMF, or initial mass function, is a statistical distribution that describes the relative number of stars with different masses in a given stellar population.
Stellar kinematics can be measured through various observational techniques, such as spectroscopy, astrometry, and photometry. These methods allow us to study the motions, positions, and properties of stars in a given population.
Stellar kinematics can provide valuable insights into the IMF of a stellar population. By studying the velocities and orbits of stars, we can infer their masses and determine the shape of the IMF, as well as any variations in it.
The IMF plays a crucial role in the process of star formation. It determines the number of stars that will form in a given region and the distribution of their masses. This, in turn, affects the evolution of galaxies and the chemical enrichment of the Universe.
Studying stellar kinematics and the IMF can have various applications, including understanding the formation and evolution of galaxies, constraining the properties of dark matter, and testing theories of star formation. It can also provide insights into the physical processes that govern the birth and death of stars.
