Origins: From Early Universe to Extrasolar Planets

Proceedings of the 19th Nishinomiya-Yukawa Memorial Symposium

Edited by Shin Mineshige and Shigeru Ida

Probably the most fascinating and attractive research frontier in the field of modern astrophysics will be to clarify the origins and subsequent evolution of various astrophysical objects in the Universe. Together with recent rapid developments of multi-wavelength observations it has become possible to get more and more vivid view of the evolution of our world. The 19th Nishinomiya-Yukawa memorial Symposium (Nishinomiya, November 1-2, 2004) was designed to provide an opportunity to discuss the latest developments towards our ultimate understanding of the origins of astrophysical objects.

When and how was this world created? Our universe is full of various states of matters. We also observe a variety of astrophysical objects, including planetary systems, stars, galaxies, clusters of galaxies, and so on. Further, we know the existence of something exotic, such as black holes, dark matter, and dark energy, the nature of which we have not fully understood yet. These have been created in the evolution of the universe and are themselves evolving, having been affecting each other.

This Supplement contains the lectures presented at the symposium. The lectures are on theoretical and observational subjects, with special attention on the first objects (first stars, supernovae, protogalaxies, and black holes) and the extrasolar planetary systems. This volume will be a good reference to all the researchers and, especially, graduate students who are starting the origin researches.
