👉 Spheniscine is a term used in the field of astrophysics to describe the structure and properties of stellar companions, or "spherii," which are objects orbiting stars. These spherii can be either black holes (like our sun) or neutron stars, depending on their mass and spin rate. Spheniscines are thought to have a complex environment that includes both gas and dust, and they may also be part of the larger galaxy, known as the circumstellar disk
