AbstractThe “telescopic” gravodynamics of the MACH‐EINSTEIN‐Doctrine gives expanding “MACHian clouds” as world models. The universe becomes a closed system (according to the classical statistical mechanics) if and only if the total energyHof this cloud, i.e. its HAMILTONian, vanishes. This cloud is the MACHian equivalent to the EINSTEIN‐deSITTERuniverse of general relativity (or of “NEWTONian cosmology”). However, the MACHian cloud withH= o describes a linearly e

摘要:

AbstractA catalogue is given of the 179 known galaxies within 10 Mpc. The inclusion of a galaxy depends on its redshift (v0≤ 500 km s−1) or, in the case of 7 dwarf galaxies, on the fact that their distances are known to be small. The catalogue contains in addition 52 more distant galaxies withv0≤ 500 km s−1: 50 are bona fide Virgo cluster members and 2 are members of the Leo group. Positions, types, absorption‐corrected luminosities, and velocities are given for the catalogue galaxies. The catalogue is believed to be nearly complete for galaxies brighter than ∽ – 18m.5, but it contains also many considerably fainter galaxies. The galaxies within 10 Mpc form the Local Group with 28 members and seven additional groups with a total of 92 known members. 59 galaxies (33%) do not seem to belong

摘要:

AbstractThe consequences of a pure power law luminosity function on the distribution of objects in the HUBBLEdiagram are described. As long as such a law acts, magnitudes do not contain any information on distances. A high value of the coefficient of the luminosity function of radio quiet quasars,b= 0.95 ± 0.05 in the expression lg ψ(M) ∽b. M, is shown to be plausible. This implies a high density evolution, ǫ ∽ (1 +z)k, withknear 9–10. Findings from modern samples, searched on low‐dispersion spectral plates point to an even stronger evolution atz3 (about 30) for these radi

摘要:

AbstractFurther investigations of the Ap star γ Equ (SCHOLZ, 1975) showed that a very slow variation of the longitudinal magnetic field exists, with a change of sign in the years 1970/1971. In three spectrograms obtained near of the crossover points of the longitudinal magnetic field hints are given at the presence of a transversal magnetic field of about 3500 Gauß. The radial velocity measurements show no definitive variation
