Aims
- To observe a number of variable stars over the course of multiple weeks.
- To use the programming language Python to analyse the magnitude of these stars as a function of time
- To determine both the variable period and variation in magnitude of these stars
- Prior to this, take dark frames as detailed in Data and Logs dark study
- Use Python to analyse these dark frames via Histogram plots and plots of column mean and standerd deviation, to determine if the pixels follow a Poisson distribution.
- To compare my results regarding dark frames with Chris Haynes and Ryan Cheale's results.
List of Potential Targets
- Gamma Cassiopeia - Variable Star (Gamma Cassiopeia Variable), magnitude variation 1.5 - 3.0, period 0.7 day, Good Visibility
- Delta Cephei - Variable Star (Cephid Variable), magnitude variation 3.5 - 4.4, period 5.4 day, Good Visibility
- Beta Persei - Variable Star (Algol Variable), magnitude variation 2.1 - 3.4, period 2.9 day, Good Visibility
- Eta Aquila - Variable Star (Cephid Variable), magnitude variation 3.5 - 4.4, period 7.2 day, Poor Visibility
- RR Lyrae - Variable Star (RR Lyrae Variable) magnitude variation 7.06 - 8.12, period 0.6 day, Good Visibilty
