Course content

This course provides an advanced introduction to radiation transport applied to stellar atmospheres and numerical stellar atmosphere models, non-LTE and numerical methods in radiation transport.

Learning outcome

After completing this course:

  • you will have knowledge of spectral line formation without using the approximation of Local Thermodynamic Equilibrium (non-LTE).
  • you will have knowledge of basic numerical methods in non-LTE radiative transfer.
  • you will understand basic concepts in stellar atmosphere modeling.
  • you will be able to apply these methods to solve a stellar atmosphere modeling problem in the form of a term project.
  • you can present the results of the term project in a written report in the style of a research paper.

Overlapping courses


Teaching extends over one semester. There will be 2 hours of lectures/tutorials each week in the first half of the semester. During the second half of the semester students will be working on a project assignment and receive individual supervision.


This course has a final oral examination and a compulsory project assignment which counts 100% in the grade assessment. The final grade is determined after an overall assessment of the two parts.

It will also be counted as one of the three attempts to sit the exam for this course, if you sit the exam for one of the following courses: AST9410 – Stellar Atmospheres (discontinued)

Examination support material

No aids allowed during the oral examination

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.

Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.

Special examination arrangements, use of sources, explanations and appeals
