javaHRD - An interactive Hertzsprung-Russell Diagram

Load javaHRD

A Java-applet has been developed to display tracks of evolution of stars as they are given in a Hertzsprung-Russell Diagram (HRD). This form of display is especially useful for beginners in astronomy.

The Java applet allows to highlight various parts of the evolution and special regions in the HRD. Several more features are available.

The applet has been developed at the Argelander-Institut für Astronomie of the University of Bonn.

Full german documentation "The javaHRD" by C. Carazo is available (diploma thesis; 2006, Univ. Bonn).
