In this workshop we present three lesson activities to teach core (astro)physics concepts at pre-university level which students find difficult to grasp with traditional interventions: star properties, star states and the fusion-gravity balance. In each activity, students construct and simulate a conceptual …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …
