The Chemistry of Star Forming Regions
1998Abstract The first generation of stars formed in gas that was almost entirely hydrogen and helium, and the chemistry that was important during their births, is treated in Chapter 3. In this chapter we focus on star forming regions in which elements more massive than helium a.re important in the chemistry that controls star formation ...

Chemistry of Star-Forming Regions
2017Birth of protostars significantly affects chemical compositions of parent molecular clouds. Observational results of low-mass and high-mass star-forming regions are summarized, which show significant chemical differentiation within a source as well as among sources.

Kinematics of Star-Forming Regions
2015The previous chapters on star-forming regions have focussed on the spatial distributions of gas and stars. This chapter therefore focusses on the internal kinematics of the young stars within the star-forming regions. Our discussion covers the kinematics of objects in OB associations and young star clusters as well as star-forming regions, detailing ...

Masers in Star-Forming Regions
1999The subject of astronomical masers is now more than forty years old, and as a consequence, several good reviews have appeared in print. For the readers who want to enter the subject of astronomical masers in a serious way, we want to recommend two reviews (Elitzur 1982; Reid and Moran 1988) and a book (Elitzur 1992a).

Clumpiness in Star Forming Regions
Astrophysics and Space Science, 2003In this article, some aspects of the clumpy nature of molecular clouds are reviewed. In particular the observational evidence for small-scale structures both in low and high mass star forming regions will be discussed. I will review some examples of `clumpiness' such as: i) the molecular clumps ahead of HH objects and how the study of the physical and ...

Overview of Star-Forming Regions
2015The dynamical evolution of young star clusters and associations is an evolving interplay of the gravitational potential, as determined by the spatial distribution of volume densities and the motions of both the gas and stars. In this chapter we briefly discuss several nearby star-forming regions which are relevant to our discussion on the dynamics of ...
