... and the kinematics of stars depends mainly upon the dynamic state of the interstellar gas at the time of star formation; the dynamic state of the interstellarmedium is always inhomogeneous and stars of different metallicities are born in different places ...
... The results can be explained if the stars were born in a chemically inhomogeneous interstellarmedium whose mean metallicity had been increasing with time. ...
... of the chemical evolution of the Galaxy: it suggests that the spatial distribution of metal abundance in the interstellarmedium was initially highly inhomogeneous, the inhomogeneities being smoothed out and the mean metallicity being increaswd as the ...
... Al the same time, the dynamic state of the interstellarmedium chages, resulting in a reduction of the dispersion of peculiar velocities of stars that form form it. ...
... Apparently, the interstellarmedium did not undergo deep mixing in the process, since we observe a strong, negative vertical metallicity gradient with virtually no radial gradient in this subsystem. ...
