Well let's be more precise. If we assume that this is not the exhaust of an engine pointed towards the camera and that is an astrophysical object (because you said it's all procedurall), then:
1.- The star and the planetary object (planet or moon) are in different systems or at least both are in a multiple system with the star being part of another ramification of the nested hierarchy of the system and very far far away (not to much since it's emmiting red and therefore it probably has not too much luminosity). This is because the phases of the planet are not aligned.
2.- Because of the first point this image has to be taken with an extremely tiny FOV
3.- It's also clear for the first image that the star is closer to the camera and the planetary object is behind it from our point of view.
Having this in mind, I would say it's some kind of low temperature star, like M-type in a binary system where there is another star of higher type (F-type or G-type) illuminating a planet. The camera is positioned near the M-type star pointing towards the planet with a tiny FOV.
There is still something strange about this. I have the feeling that the disk of the star is not a perfect circle
