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.

The course is given during daytime and is part of the Bachelor’s Programme in Astronomy. You can also take the course as a freestanding course if you fulfil the entry requirements. The course is taught in English.


Teaching Format

The teaching consists of lectures, where preparation before each session is very important. Scheduled problem‑solving sessions with teachers are also offered. The course additionally includes a mandatory computer laboratory.


Assessment

The course is examined with a written examination and hand-in questionnaires during the lectures.

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.


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 at the Stockholm University digital teachning plattform.

Course reports are displayed for the three most recent course instances.
