International Olympiad Astronomy and Astrophysics (IOAA) 2019 is a competition for high schools held internationally in the lines of other International science olympiads which covers the fields of Astronomy and Astrophysics. It is an annual astrophysics and astronomy competition for students of high school. It is one of the international science olympiads.
The Olympiad was founded from a dissidence inside the International Astronomy Olympiad in order to increase the scope of the organization.

  • Practical Competition – The organizer may provide a set of task comprising of

1) observation, 2) paper-based practical problem, 3) computer-based problem, 4) planetarium simulation or combination of the four which is expected to be solved in a duration of 5 hours. The problems provided should involve at least 4 areas as mentioned in the syllabus.

The competition days sequence is to be decided by the organizer of the competition. There must be 1 free day within the two parts of the competition.

The Olympiad duration should normally be of 10 days including arrival and departure days.

While solving the problems, contestants can use non-programmable pocket calculators without graphics and drawing materials, as brought by contestants themselves. Formulae collections from chemistry, mathematics, physics, etc., are restricted.

Marking Scheme

The theoretical part makes 50 % of the total mark and the practical part 50 % (25% data analysis and 25% observation) of the total mark. The practical solutions should consist of theoretical analysis (plan and discussion) and practical execution. The solution to each problem should contain an answer and its complete justification.
