论文摘要
我们介绍了一种分析小行星稀疏光度数据的新方法，并将其应用于木星木马小行星的Zwicky瞬态设施观测。该方法依赖于创建可能性模型，该模型包括在未知旋转阶段旋转亮度变化的概率分布。通过马尔可夫链蒙特卡洛（Monte Carlo）分析了可能性模型，以量化我们的参数估计值中的不确定性。使用此方法，我们为1049木星木马提供了颜色，相位参数，绝对幅度和旋转测量的幅度。我们发现相位参数与颜色相关，而木马小行星旋转幅度的分布与主皮带小行星没有区别。
We introduce a new method for analyzing sparse photometric data of asteroids and apply it to Zwicky Transient Facility observations of the Jupiter Trojan asteroids. The method relies on the creation of a likelihood model that includes the probability distribution of rotational brightness variations at an unknown rotation phase. The likelihood model is analyzed via a Markov Chain Monte Carlo to quantify the uncertainty in our parameter estimates. Using this method, we provide color, phase parameter, absolute magnitude and amplitude of rotation measurements for 1049 Jupiter Trojans. We find that phase parameter is correlated with color and the distribution of Trojan asteroid rotational amplitudes is indistinguishable from that of main-belt asteroids.
