چکیده

We use a Monte Carlo technique together with a simple model for the distribution of dust in M31 to investigate the observability and spatial distribution of classical novae in M31. By comparing our model positions of novae to the observed positions, we conclude that most M31 novae come from the disk population, rather than from the bulge population as has been thought. Our results indicate that the M31 bulge–to–disk nova ratio is as low as, or lower than, the M31 bulge–to–disk mass ratio.

Modelisations of galactic 1.275 MeV emission produced by the decay 22 Na have been performed for several frequency-spatial distributions of ONe novae. Recent results of nova rates and their distributions in our Galaxy have been used. These modelisations allow to estimate the lower-limit of the 22 Na mass ejected per ONe novae detectable with the future spectrometer (SPI) of the INTEGRAL observa...

Measurements of the linear diameters of 12 nearby spiral galaxies with distances determined from primary indicators suggest that both the Milky Way Galaxy and M31 are in the middle of the range of sizes for such galaxies. By comparing the measured linear diameters of these nearby systems with the inferred diameters of a sample of more than 3000 spirals with known redshifts, we conclude that the...

The theory of inertial induction, which has been quite successful in explaining a number of hitherto unexplained astrophysical phenomena, predicts a redshift in light grazing massive objects. The total solar eclipse on 11 August 1999 offers an opportunity of testing the theory. In this paper we predict the additional redshift of a few stars during the eclipse and urge professional astronomers t...
