Lecture 1: Cosmic nucleosynthesis and astronomical tools

Nucleosynthesis in cosmic sites occurs under extreme environmental conditions. These often prevent observational access, from overlying matter that absorbs any direct signals, or from the extreme conditions where different messengers appear.
We discuss the direct and (mostly) indirect ways one may be able to record signals about cosmic nucleosynthesis. Herein, we will discuss how one may address the inherent experimental difficulties and observational biases.

Lecture 2: Gamma-ray astronomy: Profile of a difficult experimental-physics field

Gamma-ray telescopes have been established in the recent decades. With the prospect
of rather direct observations of cosmic nucleosynthesis signals, hopes were great
50 years ago. But we will discuss the experimental difficulties that are faced by the different telescope designs, and present the two legacy space missions together
with future prospects of this field of astronomy

Lecture 3: Lessons from gamma-ray spectroscopy

As one example of the astronomy of cosmic nucleosynthesis, we present the measurements made in gamma rays from radioactive decays of short-lived isotopes that are a by-product of nucleosynthesis processes in cosmic sites. We discuss what has been learned about stars and stellar explosions, and how their ejecta are distributed towards next-generation star formation.

Galactic chemical evolution

Lecturer: Chiaki Kobayashi (University of Hertfordshire, UK)

Observational night and hands-on stellar spectroscopy

Lecturer: Tiina Liimets (Tartu Observatory, Tartu University, Estonia)
Brankica Kubatova (Ondřejov Observatory, Czech Republic)

"Observing in a nutshell – NOT”

We will be giving an overview of the Nordic Optical Telescope (NOT) as well as the spectrograph FIES we are going to use in our observing night. In addition, the lecture will contain information how to prepare for the observing night.
