Scientific hopes and aspirations

However, this is not the end of the story. Calcnlations carried ont in a spherically symmetric context mnst now be extended to inclnde clearly or subtly anisotropic effects, in order to model jets, rotation and the like. Three-dimensional numerical simulation is required. Astrophysicists should proht from considerable progress made in hydrodynamics with the development of extremely powerful lasers in France and the United States, but that is another Story.  

These are therefore the main hues of research into galactic evolution. However, stellar archaeology is still in its early stages. In future years it will obtain a signihcant boost from the VLT and its high-quality spectrographic observations, to become eventually a major branch of astronomy. 

One cannot overemphasise the importance of accurate abundance measurements and estimates of the errors involved in them. If suitable data are unavailable, or if their quality cannot be properly assessed, it is quite impossible to draw astrophysical conclusions. In this respect, systematic observation campaigns are preferable, collecting large and uniform samples of good quality. One might seek to achieve the aims on the following hst  

Lithium, beryllium, boron and the controversy over oxygen and the origin of the light elements 

As the halo stars tell us, oxygen was overabundant with respect to carbon and iron in the adolescent Galaxy. This has been well established for a number of years now. However, debate has rekindled over the amplitude of this oxygen excess and its variations as a function of metallicity.
