用于行星历表中主带小行星选择的提升决策树：一种替代模型

Boosting decision trees for Main Belt Asteroid selection in planetary ephemerides: an alternative model

针对行星历表中主带小行星质量建模参数过多的问题，提出基于提升决策树的小行星选择替代模型，以减少质点小行星及拟合参数，同时保持后验拟合残差不显著恶化。

Fast algorithms for slow moving asteroids: constraints on the distribution of Kuiper Belt Objects

We introduce a new computational technique for searching for faint moving sources in astronomical images. Starting from a maximum likelihood estimate for the probability of the detection of a source within a series of images, we develop a massively parallel algorithm for searching through candidate asteroid trajectories that utilizes Graphics Processing Units (GPU). This technique can search over 10^10 possible asteroid trajectories in stacks of the order 10-15 4K x 4K images in under a minute using a single consumer grade GPU. We apply this algorithm to data from the 2015 campaign of the High…

125万颗主带小行星的平近点角轨道目录及136个新碰撞族的发现

Catalog of Proper Orbits for 1.25 Million Main Belt Asteroids and Discovery of 136 New Collisional Families

本文提出了一份包含125万颗主带小行星平近点角要素的新目录，并基于该目录系统搜索发现了136个新的小行星碰撞族，详细分析了若干年轻族的特性。

Evaluation of Mother-Daughter Architectures for Asteroid Belt Exploration

This paper examines the effectiveness of an asteroid exploration architecture comprised of multiple nanosatellite sized spacecraft deployed from a single mother ship into a heliocentric orbit in the main asteroid belt where the mothership is ideally located in region of high density. Basic mission requirements associated with a Mother-Daughter architecture are established utilizing a relatively large number (10-20) daughter spacecraft distributed from a mothership within the asteroid belt for the purpose of executing sample and return missions. A number of trade analyses are performed to estab…

基于暗能量巡天数据的主带小行星分类学信息

Main belt asteroids taxonomical information from Dark Energy Survey data

本研究利用暗能量巡天（DES）数据，结合交叉关联与经遗传算法优化的机器学习方法，为6.8万余颗无分类信息的小行星判定C/S类群归属，并新发现409颗可能的V型小行星，填补了小行星分类数据的缺口。

JWST 观测到主带十米级小行星及其对陨石来源的启示

JWST sighting of decameter main-belt asteroids and view on meteorite sources

本文利用JWST红外能力与合成跟踪技术首次在主带探测到138颗十米级最小小行星，发现其尺寸-频率分布在约100米处出现拐折，并指出其来源于Nysa、Polana和Massalia等小行星族，为理解近地天体与陨石来源提供了关键观测约束。
