Supernovae and interstellar gas dynamics

Symposium - International Astronomical Union, 1967
The efficiency of the transfer of energy from supernovae into interstellar cloud motions is investigated. A lower limit of about 0·002 is obtained, but values near 0·01 are more likely. Taking all uncertainties in the theory and observations into account, the energy per supernova, in the form of relativistic particles or high-velocity matter, needed to

Whistlers in interstellar gas dynamics

AIP Conference Proceedings, 2002
Based on equation of electromagnetic induction for the magnetic flux density driven by Hall and Ohmic components of electric field generated by flows of thermal electrons an analytic model of helicoidal magneto-electron waves, whistlers, is developed.

Interstellar Gas Dynamics

Publications of the Astronomical Society of Australia, 1968
It is a well established observational result that young stars exhibit differences in chemical composition. The differences are comparatively large. For example, some stars have metal abundances as high as 3/2 solar-value while others have abundances as low as 1/2 solar-value.
