Optical velocities of semi-regular (SR) and irregular (Lb) variables are analysed for a K-term. There is evidence for a dependence upon stellar period. Absorption lines in shorter period non-emission SR variables are ...

We have recalculated the processes e ν → e ν and e + e − → ν ¯ ν due to an assumed magnetic moment κ of the neutrino (correcting some errors in the previous calculations). Comparing the results with ...

The processes ν ν → ν ν , ν ¯ ν → ν ¯ ν , ν ¯ ν → 2 γ , and ν γ → ν γ , which are of astrophysical interest, are calculated both in the electroweak model and in the magnetic model when the ...

We investigate the conditions of the vanishing cosmological constant and the presence of gravity and vector gauge fields in a D -dimensional non-Abelian Kaluza-Klein theory based on a dimensionally continued ...
