论文摘要
我们报告了使用4.3 m Lowell Discovery望远镜以11.89 au为中心的4.3 m Lowell Discovery望远镜回收返回的HALLEY型彗星12p/pons-brooks。与灰尘模型的比较分析表明，由于来自太阳的$ \ sim30 $ au，该彗星可能已经活跃。我们从细胞核光度法中得出了$ 17 \ pm6 $ km的核半径，尽管由于灰尘和气体的污染，该数字可能高估了。预计该彗星将于4月2024年即将到来的围部，鼓励继续进行监测。
We report the recovery of returning Halley-type comet 12P/Pons-Brooks using the 4.3 m Lowell Discovery Telescope, at a heliocentric distance of 11.89 au. Comparative analysis with a dust model suggests that the comet may have been active since $\sim30$ au from the Sun. We derive a nucleus radius of $17\pm6$ km from the nucleus photometry, though this number is likely an overestimation due to the contamination from dust and gas. Continuing monitoring is encouraged in anticipation of the comet's forthcoming perihelion in 2024 April.
