9. Course learning outcomes

You will know the chemical and physical composition of the interstellar medium (ISM) regarding its gas and dust components. You will know the principles that determine the physical state of the ISM and understand the relationships between the ISM properties and the radiation observable from the ISM. You are able to analyse astronomical data and estimate basic ISM parameters (temperature, density, kinematics) based on observations.


10. Course completion methods

Weekly exercises and a final project work or a final exam (to be decided at the beginning of the course). The exercises may include simple programming tasks. The final project work can consist of a literature study or the analysis of actual observations.


11. Prerequisites

Basic course of observational astronomy II (Havaitsevan tähtitieteen peruskurssi II). Basic courses of astrophysics (Astrofysiikan peruskurssi I-II) are strongly recommended.

12. Recommended optional studies

13. Course content

The course covers the properties and physical processes in the

interstellar medium (ISM), especially in connection with star formation.

The course starts with a general description of the structure, evolution, and properties of the ISM, with an emphasis on dense molecular clouds. We will then study the interplay of gravity, turbulence, and magnetic fields that leads to the formation of dense cores within the molecular clouds and, as a result of their collapse, to the formation of new stars. The gravitational and thermal balance and the chemical evolution of the ISM along the star-formation process will also be examined. The course ends with a discussion of the observable properties of young stellar objects.

14. Recommended and required literature

Lecture notes and  Ward-Thompson & Whitworth: An introduction to star formation

Supplementary reading

  • Draine: Physics of the interstellar and intergalactic medium
  • Selected research papers (links will be provided on the course website)

15. Activities and teaching methods in support of learning

Weekly lectures and exercises (individual work) and a final project (individual). Total hours 130.


16. Assessment practices and criteria, grading scale


Final grade is based on the exercises (50%) and the final project or exam (50%).

17. Teaching language

English
