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. This work is funded through the Planetary Astronomy Program in the Division of Astronomical Sciences.***

AST 0073837特德斯科博士。 Tedesco 将开发一个小行星带的三维模型，其中包括所有亮度超过视星等 25 等的小行星的轨道元素、直径和反照率。然后，该模型将利用现有和同时期的目视至红外波长观测得到改进。改进后的模型将用于完善我们对当前小行星尺寸频率分布的了解，并帮助规划未来在解决这一问题的波长上的观测。测量的大约 2,400 个小行星的反照率将用于估计缺乏反照率和直径的真实小行星的反照率和直径，并生成统计小行星的反照率和绝对星等。这项工作由天文科学部的行星天文学计划资助。***
