Simulated Asteroid Belt Population Model

AST 0073837TedescoDr.特德斯科将开发一个小行星带的三维模型，包括轨道要素、直径和所有可能变得比视星等25更亮的小行星的半径。然后，将利用现有的和同时期的观测结果，从可见光到红外线波长，对这一模型进行改进。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，并帮助规划今后在这些波长上进行的观测，以解决这一问题。将利用对大约2，400颗小行星测得的日冕度来估计缺少日冕度和直径的真实的小行星的日冕度和直径，并计算统计小行星的日冕度和绝对星等。这项工作是由天文科学司的行星天文学计划资助的。

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.
