Variable stars (PAP313: 5pts )

Timetable in autumn 2018

Main idea of the course

Simulated and previously unpublished photometry of a chromospherically active star are analysed. Detailed modelling of the light curves is performed. The applied new period analysis method is from | Jetsu (2018) |. Print this paper and keep it with you in every lecture. There are no exams. The students will perform personal assignments. The number of assignments completed by the student determines the grade received of this course. The aim is to report the results in a refereed paper, where the authors will be all the students that pass the course. The best student will be the main author. There will be N=10-12 exercises. The evaluation criteria of each Exercise are

  • 0/2 (Exercise not done at all, or it makes no sense)
  • 1/2 (Exercise is a good try)
  • 2/2 (Exercise is correct, or nearly correct)
  • The maximum points are NMAX = 2 x N pts. The grade limits are

  • 0/5 = <45% of NMAX
  • 1/5 = 45-55% of NMAX
  • 2/5 = 55-65% of NMAX
  • 3/5 = 65-75% of NMAX
  • 4/5 = 75-85% of NMAX
  • 5/5 = <85% of NMAX
