binary lensの例文

• Caustic crossings in binary lenses can happen with a wider range of lens geometries than in a single lens.
• These include very high magnification events, binary lenses, parallax, and xallarap events, and events where the lens is visible.
• As in the single lens case when the source magnification is formally infinite, caustic crossing binary lenses will magnify different portions of the source star at different times.
