61Photometric system — In astronomy, a Photometric system is a set of well defined passbands (of filters), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a… …
62UBV photometric system — UBV photometric system, also called the Johnson system (or Johnson Morgan system), is a wide band photometric system for classifying stars according to their colors. It is first known standardized photoelectric photometric system. The letters U,… …
63Methods of detecting extrasolar planets — Any planet is an extremely faint light source compared to its parent star. In addition to the intrinsic difficulty of detecting such a faint light source, the light from the parent star causes a glare that washes it out. For those reasons, only a …

65Exoplanetology — is the Art and Science of Exoplanets and the search for Life on other Worlds. It is formally defined as the study of the characteristics, formation and fate of planets outside our solar system. The discovery of extrasolar planets or exoplanets in …
66Constellation model — The constellation model is a probabilistic, generative model for category level object recognition in computer vision. Like other part based models, the constellation model attempts to represent an object class by a set of N parts under mutual… …
67Moons of Haumea — Keck image of Haumea and its moons. Hiʻiaka is above Haumea (center), and Namaka is directly below. The outer Solar System dwarf planet Haumea has two known moons, Hiʻiaka and Namaka, named after Hawaiian goddesses. These small moons were… …
68Bande B — Système photométrique En astronomie, un système photométrique est un ensemble choisi de filtres, chacun ayant une bande spectrale bien définie, et couvrant généralement le domaine optique (ou visible ) du spectre électromagnétique. Sommaire 1… …
