Observation of multiple stars
The purpose of the course is to observe and study the characteristics of more than a hundred multiple stars, both optical and those linked by gravity.
Course with a duration of 34 hours, distributed over 17 sessions, with one session per week.
|In this course we will observe and study the characteristics of over 100 multiple stars, both optical and gravity-bound. In the sky we can see stars that are very close to each other; given their appearance, we call them double or multiple stars. These can be stars that appear to be occupying the same position in the sky but are actually at different distances, called optical doubles, or they can be stars that actually are close to each other and orbit around a common center of mass, in which case they are known as binary stars, with 2 or more components. Since they appear so close together, their different tonalities, due to temperature differences, can be distinguished, although this spectacle is invisible to the naked eye.|
|Anyone interested in observing a spectacle that is invisible to the naked eye.|
