Trapezia may also evolve dynamically in a less violent way, if they start out from a virialized state (Allen et al. 1974b). In this case, the time scale for their dynamical evolution is ab ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
