Possibility of Mass Loss in the Red-Giant Stage from H-R Diagrams of Galactic Clustersisochronous curves without mass loss derived from Iben’s evolutionary tracks and time scales for Population I stars. Interpreting the difference in magnitude between the theoretical positions thus calculated and the observed ones as due to mass loss, when negative, the results indicate that this los

Coronae Around Helium Stars and X-Ray Sourcest log . = 4 and 15000K at log . = 6. The author’s suggestion in his last paper that a helium star . Sgr may have a corona seems to be justified. X-ray from a corona around a helium star is strongest when the physical parameters of the star are logg ~ 6 and T. ~ 15000K. But the total energy flux is t

Starke Verschiebungen und Aufspaltungen fallen auch in polykristallinen Proben auf. Hinzu kommt, daß eine regelmäßige und räumlich dichte Anord
