This course has been specifically designed at the request of the Severo Ochoa IAA Scientific Committee. It is specially addressed to IAA staff with other non-specific training in astrophysics (electronic engineers, mechanics, computer scientists, etc.) . This course is intended to be a tool to facilitate the work of all personnel who do not have training in these subjects, but who are immersed in their day-to-day work in a multidisciplinary work environment. The content covers all the basic points of astronomy and astrophysics on which to build a subsequent more in-depth study of each subject.
