The problems connected with phenomena to be observed.in variable stars must1be,
investigated and solved in consideration of the-mechanic effects of gas dynamics.
Observations haveabove all shown that on the occasion of the flashing up.of
...novaeland supernovae.radial gas motions with velocities. of tile orders .1000,to.,
6ooD km/sec occur. The following problem first arises on this occasion: What is
it we observe ? Is it thefront edge.of the expanding star surface,or the front,
of a shock which expands in the clomparatively:eold fog.which.purround5the star ?
The most probable hypothesis is that of the expansion of the s4ar After the
:fashion of-a sphere of gas in a vacuum',(or in a.very thin atmos~here)..ffhen.in-
vestigating the explosions preceding the star explosions and causing the explo-
sions, those detonation phenomena,must be investigated which are connected with,
the existence of"jum s''.( = compression shocks ?). The latter expand within the
p~
gas masses of the stars and transport a considerable amount of energy,on',to the
star surface.

gas behind the:shock wave. This caused doubts as to the physical reality of
such models.
In the case. of 4/3 and at (J 2, 5 the author obtained solutions with
,.,finite-initial energy and finite energy of the disturbed motion. On this oc,ca-
sion cavities form in the center,of the star in the case of strong shock waves
with the pressure zero, but in the case of weak
~shock waves no cavities are
;formed. The spherically.symmetric gas motion is also investigated without

,ducing hiCh pressures and temperatures. (According to the reviewerls:opinion
