Using AIJ for Double Stars

AstroImageJ (AIJ) is the industry standard for measuring exoplanet transits as well as accurately measuring double stars, and has quickly become a core component of the astronomical sciences. This video is a guide and reference for anyone using AIJ for double stars measurements.


Double Stars Overview

By determining the gravitational or mutual orbit of two stars using astrometry, it is possible to derive stellar mass and consequently contribute to and refine contemporary astrophysical theories and knowledge.


Astrometry Overview

Astrometry is the area that deals with the positions and motions of celestial objects. It has two main scientific objectives to provide: A stellar reference frame to which the motions of celestial objects (Solar System and beyond) may be referred Basic...
