The stellar halo of the Galaxy
- Physics, Geology
- 2008
Stellar halos may hold some of the best preserved fossils of the formation history of galaxies. They are a natural product of the merging processes that probably take place during the assembly of a…
Unstable objects in the galaxy and the star-formation process
- Physics
- 1995
Using observational data, we consider the problem of instability of astronomical objects and systems of objects and its close connection with the star-formation process. We show that it is only due…
Status of Cosmological Parameters
- Physics
- 1998
The cosmological parameters that I will discuss are the Hubble parameter H 0 ≡100h km s-1 Mpc-1, the age of the universe t 0, the average density Ω0, and the cosmological constant Λ. The most…
Detailed Analysis of Nearby Bulgelike Dwarf Stars. II. Lithium Abundances
- Physics, Geology
- 2002
Li abundances are derived for a sample of bulgelike stars with isochronal ages of 10-11 Gyr. These stars have orbits with pericentric distances, Rp, as small as 2-3 kpc and Zmax < 1 kpc. The sample…
The New Galaxy: Signatures of Its Formation
- Physics
- 2002
▪ Abstract The formation and evolution of galaxies is one of the great outstanding problems of astrophysics. Within the broad context of hierachical structure formation, we have only a crude picture…
The Cosmic Century

- 2006
Part I. Stars and Stellar Evolution up to the Second World War: 1. The legacy of the nineteenth century 2. The classification of stellar spectra 3. Stellar structure and evolution 4. The end points…
The Fundamental Parameters of Cosmology
- Physics
- 1999
I describe the evidence for the big bang, including the various cosmological parameters. There is general concordance on their values, although the uncertainties remain large enough to justify the…
Cosmological Parameters and Galaxy Formation
- Physics
- 2000
There are ten critical cosmological parameters that monitor cosmo-logical models and structure formation. In this review, I summarize the current status of these parameters and discuss the issues…
