Stars in a galaxy    

Allocation of stars in an elliptic galaxy is uniform. It is known that the allocation of stars in an elliptic galaxy is extraordinary uniform and is not present any hint on an interior structure. What the parent of such allocation in, it remains the  unknown.

From Unified Тheory (Space vortex changes see) it is followed that the more galaxy density (the quantity of stars in unit volume), the less its structure is distinguished and at transition from the spiral phase to the globe phase the luminescence is became more and more uniform. Besides the velocities of the stars and the density will be well intermixed as a result of the active processes (Globe galaxies – places of the improbably powerful activity see) .

Secret of a variance of the velocities of stars of the late classes. It is known that «the stars of the late classes have higher variance of the velocities, than the stars of the early classes» [18, p. 129]. The explanation to it misses.

According to Unified Тheory (The velocity grows to the central region of the vortex see) the flow rate of ether in the galaxy "sleeves" is increased at the approaching to its kern. Accordingly the forward stars progressively increase the velocity in comparison with the back stars, that in the closer (to the galaxy kern) field gives the greater variance of velocities of this stars. But as closer to a kern of the galaxies there are more the stars of the late classes ("In the kern of galaxies are the old stars" look a little lower), then the greatest variance of the velocities is reached namely at them.

Why out of  galaxies stars are a little. It is known that out of galaxies it is a little of stars. Existing explanations of this fact have the fragmentary character and are insufficiently clear. Unified Theory of  Nature explains this fact.

So from Unified Тheory it is  followed that vortexes can be formed only  at the converging fluxion (to сonverge, means, already to collide, Formation of galaxies and stars see). But the converging macrofluxion (the convergence) on Unified Тheory precedes directly to the formation of a macrovortex – of a galaxy, but  the converging mesofluxions, transmuting in the mezovortexes – the stars, can arise earlier also, but not so frequently, as at formation of the more dense converging macrofluxion. Therefore on Unified Theory practically all stars should be in galaxies.

In the spiral sleeves of galaxies are the youngest stars, in the kern – the old. There is a riddle, consisting in that in the spiral sleeves of galaxies there are the youngest and brightest stars, but in a kern on the contrary. By that the young stars have smaller own velocities.

From Unified Тheory ("Space vortex changes" see above) it is visible that a spiral galaxy is the youngest, so, its stars are the youngest. These stars are disposed in the sleeves because the greatest (on a circle of the galaxy) density of ether, of which they are organized, is in the sleeves. According to ("Space vortex changes" see above) their ratation velocity gradually with the age (i.e. with magnification of the steepness of the star-bearing sleeve of the galaxy) will be increased. In the kern the process has begun earlier, therefore there stars are the less bright (Formation of new stars  in a galaxy see).

The brightest stars are on boundaries of galaxies sleeves. One more secret of spiral galaxies:  the brightest stars are disposed on boundaries of sleeves of the spiral galaxies.

It is explained by Unified Тheory ("Formation of galaxies and stars" see above and classification of the types of galaxies see) that the sleeve – a branch of the major vortex – of the macrovortex, and nearby it is the ether of the smaller density and of the motion in the mach less intensive. As the result on the boundary of such fluxions is appeared the earliest (the bright) mesovortexes (the stars). They  are younger than the stars in the sleeve, since the ether motion transfers the stars not only along a sleeve, but also to a sleeve (from the sleeve sides) and further in the sleeve (Flow of ether see).
