bullet::::- ultra series (1966–), a long-running television and film tokusatsu series featuring the ultramen (also known as the ultras), created by tsuburaya productions. the land of light is a massive world located in nebula m78. the ultra homeworld, the land of light consists of a collection of levitating emerald continents orbiting the planet's core. originally, the planet had its own star, but when this star gradually died and became a black dwarf, the inhabitants built the plasma spark. this artificial star provided great strength to the then human-like people, transforming them into the first ultras. the power given off by the star travelled so far when it was first switched on that it affected another planet in the neighbouring nebula l-77 (the homeworld of ultraman leo and astra), transforming the people who lived there into ultras too. the land of light is a monarchy, ruled by a king and watched over by the space garrison, an organisation that seeks universal justice and peace—unless unduly provoked. due to the strength and importance of the plasma spark, m78 has been the target for many aliens and enemies seeking to exploit or destroy it. the earliest conflict of this kind to affect m78 was the great ultra war, in which the evil alien empera attempted to take over the planet after learning of the plasma spark's power. dark zagi, the main antagonist of "ultraman nexus", tore a hole through the multiverse to reach the planet, but was repelled by the combined efforts of the space garrison and nexus's true form, noa. the renegade ultraman belial also attempted to take the plasma spark twice. in his first attempt, he was successful, but was later defeated in the monster graveyard by ultraman zero and several members of the ultra brothers. in his second attempt, he attacked the land of light directly, but his army was dealt an embarrassing defeat. many of the ultras live on the land of light or other planets in the nebula, including leo and his brother, astra, who reside in m78 after their home nebula, "l-77" was destroyed by the alien magma.

a theoretical transiting exoplanet light curve model predicts the following characteristics of an observed planetary system: transit depth (δ), transit duration (t), the ingress/egress duration (τ), and period of the exoplanet (p). however, these observed quantities are based on several assumptions. for convenience in the calculations, we assume that the planet and star are spherical, the stellar disk is uniform, and the orbit is circular. depending on the relative position that an observed transiting exoplanet is while transiting a star, the observed physical parameters of the light curve will change. the transit depth (δ) of a transiting light curve describes the decrease in the normalized flux of the star during a transit. this details the radius of an exoplanet compared to the radius of the star. for example, if an exoplanet transits a solar radius size star, a planet with a larger radius would increase the transit depth and a planet with a smaller radius would decrease the transit depth. the transit duration (t) of an exoplanet is the length of time that a planet spends transiting a star. this observed parameter changes relative to how fast or slow a planet is moving in its orbit as it transits the star. the ingress/egress duration (τ) of a transiting light curve describes the length of time the planet takes to fully cover the star (ingress) and fully uncover the star (egress). if a planet transits from the one end of the diameter of the star to the other end, the ingress/egress duration is shorter because it takes less time for a planet to fully cover the star. if a planet transits a star relative to any other point other than the diameter, the ingress/egress duration lengthens as you move further away from the diameter because the planet spends a longer time partially covering the star during its transit. from these observable parameters, a number of different physical parameters (semi-major axis, star mass, star radius, planet radius, eccentricity, and inclination) are determined through calculations. with the combination of radial velocity measurements of the star, the mass of the planet is also determined.
