Book 2018Latest editionof the new interstellar composition into next-generation stars characterises the compositional (chemical) evolution of cosmic gas in and between galaxies. Radioactive species have unique messages about how this occurs.. .Since the first Edition of this book published in 2011 with the title .Astronom

Working Smarter with Arrays and Loops,energy is produced by alternate hydrogen and helium burning in shells above the core. The long-lived radioactive nucleus.Al is produced in AGB stars by proton captures at relatively high temperatures, above 60 MK. Efficient production of .Al occurs in massive AGB stars (> 4:5 M.), where the base of

Working Smarter with Arrays and Loops,than about 100 Myr) in the Early Solar System (hereafter ESS). (3) An explanation of their existence in terms of nuclear processes. We often only have incomplete and/or qualitative views of such complex processes. Additionally, these may have occurred at a galactic scale (providing a .), or at the l

Building a Random Quotation Generator, detectable. The large number of degrees of freedom that may be present in the microscopic physics must be explored by clever variations of the experimental setup. Most astronomical observations are obviously also taken from the far field, because the distance to the observed source is so much large
