Astronomical research at VMI has developed in two directions:
- Observations of pulsating variable stars using the 20-inch reflector telescope.
- Theoretical investigations involving time-series analysis of variable star data
The VMI Observatory includes a 20-inch telescope which is ideal for obtaining professional-quality observations of pulsating variable stars. We use an astronomical CCD electronic imaging system, which is cooled to -40 degrees C to permit time exposures. The procedure is to obtain images of a small field around the variable star and then to use a few surrounding stars as comparison stars. Images are obtained in several standard filter bandpasses to obtain color information as well as the brightness changes of the variable star.
