Simulated Asteroid Belt Population Model

AST 0073837 tedescodr。Tedesco将开发一个小行星带的三维模型，包括轨道元素、直径和反照率，所有的小行星都可以变得比视星等25更亮。然后将利用现有的和同时代的可见光到红外波段的观测来改进这个模型。改进后的模型将用于完善我们对当前小行星大小-频率分布的了解，并帮助规划未来在这些波长上的观测，以解决这个问题。约2400颗小行星的测量反照率将用于估计真实小行星的反照率和直径，并为统计小行星生成反照率和绝对星等。这项工作由天文科学部行星天文学项目资助

AST 0073837TedescoDr. Tedesco will develop a three-dimensional model of the asteroid belt consisting of orbital elements, diameters, and albedos for all asteroids that can become brighter than apparent visual magnitude 25. This model will then be improved using extant and contemporaneous observations at visual through infrared wavelengths. The improved model will be used to refine our knowledge of the current asteroid size-frequency distribution and to aid in planning future observations at those wavelengths that address this issue. Measured albedos for approximately 2,400 asteroids will be used to estimate the albedos and diameters for real asteroids lacking them and to generate albedos and absolute magnitudes for the statistical asteroids.
