Collision of Galaxies : numerical simulation made by my friend Mario Juric

Nonradial Stellar Pulsations (NRP): numerical modeling of light curves calculated by my program NORSTEP. Here you can find animated example (3.1Mb) of pulsations: blue and red colors represent opposite radial deformation of the stellar surface. There is , also , example without animation.And one example of rotationally deformed star.

the Vector Spherical Harmonics are angular vectors with Real an Imaginary part. Here you can find visualization for : (l=1,m=0) (only imaginary part exist), real part for (l=1,m=1) , imaginary part for (l=1,m=1) , (l=2,m=0) (only imaginary part exist), real part for (l=2,m=1) , imaginary part for (l=2,m=1) , real part for (l=2,m=2) , imaginary part for (l=2,m=2) .
