Astrophysical Spectra

Studies of spectra are a fundamental tool in astrophysics. This course will introduce you to the tools that are required to characterize the radiation that originates in astronomical objects. Analyzing spectral observations will be your key to inferring the physical conditions that are present in the object where radiation originates.

The course treats the fundamentals that govern the formation of spectral lines in astrophysical objects. It deals with the transport of radiation through astrophysical media where absorption and emission processes together with hydromagnetic effects take place. It also treats the use of analytical and numerical models to perform calculations of the formation of synthetic spectra. All these concepts are used in applications to stellar atmospheres and interstellar gas.


  • Course structure

    The course is given in English during day time, and is part of the Bachelor’s programme in Astronomy.


    Teaching format

    We normally use a flipped classroom approach where the students are expected to read some material before the lecture. Part of the in-class time is used for problem solving with the teacher. The course has a computer lab that is mandatory.

    The course is examined as follows: Knowledge assessment takes the form of written examination and hand-in questionnaires during the lectures.

  • Schedule

    The schedule will be available no later than one month before the start of the course. We do not recommend print-outs as changes can occur. At the start of the course, your department will advise where you can find your schedule during the course.
  • Course literature

    Note that the course literature can be changed up to two months before the start of the course.

    The course makes use of notes developed by the teachers that are made available to the students on the course page in Athena.
