Exoplanet Ring Detection 2D — Sky-Plane Transit Model
Interactive 2D simulator: a ringed exoplanet's silhouette is projected straight onto the star's sky-plane disk and integrated with a polar quadrature light-curve model, showing exactly how ring tilt, position angle and optical depth turn a symmetric transit into the asymmetric ingress/egress signature astronomers use to detect exoplanetary ring systems.
A ring system around an exoplanet is far too small to resolve with any telescope, so astronomers infer it purely from how it distorts the transit light curve — a phenomenon that lives entirely in the two-dimensional sky plane. This simulator renders that sky-plane view directly: the star's limb-darkened disk, the planet's silhouette and the ring's projected ellipse, all drawn in true 2D geometry, with a light curve computed underneath by an independent polar-quadrature integration over the stellar disk. Adjust the ring's outer radius, tilt, position angle and optical depth and watch the transit deepen, stretch, and — for a ring whose position angle is neither aligned with nor perpendicular to the orbit — become measurably asymmetric between ingress and egress, exactly the deviation-from-symmetry astronomers use to flag a ringed-planet candidate.
