Techniques used in variable star research

Participants in the VSS community undertake research using a variety of techniques. You can learn more about these techniques below.


Spectroscopy is the analysis of electromagnetic radiation received from astronomical objects and is generally presented as a graph of radiation amplitude versus wavelength. Amateur spectroscopy is presently restricted to the visual range, for cost and technical reasons, but that is hardly a limitation as the interested observer will find no end of interesting objects and events to observe.
