tailieunhanh - Siriu s Matters

Astronomy is a difficult science and it is a challenge to understand even the stars that compose the brightest system on the night sky: Sirius (α Canis Majoris=α CMa). This is one of the nearest stars and the brightest one as seen from Earth, with the exception of our Sun. At present, perhaps unfortunately, stellar astronomy and in particular the study of the very bright stars are not part of the mainstream astronomy research. The professional attention is now focused on the cutting-edge of cosmology, the early Universe, extremely distant galaxies, the “origins” theme, etc. Bright stars are perceived to be too mundane to be considered an interesting. | ASTROPHYSICS AND SPACE SCIENCE LIBRARY 354 Noah Brosch Sirius Matters 0S SL 4Ù Springer Sirius Matters Astrophysics and Space Science Library EDITORIAL BOARD Chairman W.
