Eclipsedtilat

Eclipsedtilat is a fictional term used in speculative astronomy and world-building to describe a rare multi-body eclipse event in a star system. In this imagined scenario, two transiting bodies—typically a planet and a smaller satellite in a hierarchical arrangement—produce overlapping shadows on the host body, resulting in a distinctive two-phase dimming in the observed light curve that is not present in ordinary eclipses. The event is characterized by an initial rapid drop in brightness as the outer body begins to obscure the source, followed by a secondary, more gradual dimming as the inner body completes its passage, with a brief plateau during the overlap.

Etymology of the term combines the standard word eclipse with tilat, a coinage from the fictional Tilatian language in the setting. The name reflects the perceived “veil” or shadow effect produced by the overlapping shadows. In-world usage often ties the term to observational campaigns and theoretical work conducted by scientists in the Tilatian-descended cultures that populate the setting.

Occurrence and modeling in the fictional framework place eclipsedtilat in hierarchical triple systems where the orbital planes are closely aligned. Detecting such events would require precise, multi-band photometry over extended time baselines, and timing measurements that reveal the overlap of shadows. The modeling approach combines elements of classic eclipse geometry with light-curve decomposition to separate the contributions of each body’s transit and account for light-travel time effects.

Cultural and narrative significance in the fiction includes implications for navigation, calendar systems, and myth. Eclipsedtilat events serve as plot devices to explore themes of alignment, hidden influence, and the interplay of multiple celestial actors within a shared system.
