Astrophysical Jets

Simulates the bulk motion of relativistic jets coming out of a microquasar. The jets are modeled here as a pair of jets moving away from a central source. The two jets always move in opposite directions. The size of the blobs here indicates the relative brightness.

Interesting to note:

Here is the above diagram for GRS1915+105, a black hole about 11,000 parsecs distant. Note that if the approaching jet were more face-on, it would be much brighter. (More info here).

Explanatory Notes

Brightness Exponent
The change in brightness depends on the Doppler factor raised to a certain power (exponent) That exponent takes different values, depending on the character of the emitter.

θ, sp, bri
The apparent angle, apparent speed, and relative apparent brightness of the blob.
