The Companion We Have Not Found
An unusually elongated orbit motivates a possible binary-disruption history.
S301 may once have belonged to a compact binary system. This imagined pair illustrates the proposed origin, rather than an observed companion or a documented moment. AI-generated illustration.
THE OBSERVATION
What we can actually see.
Interferometric positions constrain S301’s tight, eccentric orbit near Sagittarius A*. The proposed binary origin follows from dynamics; the former partner has not been identified in the observations.
THE ILLUSTRATION
What the artwork imagines.
The two stars are cast as an intimate pair before an imagined encounter. Their separation, color, and history are inventions, not a reconstructed image of a known system.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article follows S301’s observed orbit and the future prospect of measuring Sagittarius A* spin from repeated passages. An unusually elongated orbit motivates a possible binary-disruption history.
