Variable stars discovered with the Mini Observatory

Actualizado: abr 2


During the months of November and December 2017, I dedicated the newly built Mini Observatory to the search for variable stars, finding 6 new variables that were approved and added to the VSX (The International Variable Star Index).

The equipment has proven to be a good tool for the observation of variables up to a magnitude of approximately 17V.

This is the relationship of stars:

This graph represents the phase curve of one of the variables discovered, where the measurements are indicated with red dots and the ASAS-SN data with green dots. The combination of both sources of data helps to verify and refine the data associated with the star.
