| Outline of Annual Research Achievements |
This research had two main goals: (1) How does a Kuiper Belt Planet (KBP) located beyond Neptune perturb the orbits of trans-Neptunian objects (TNOs)? (2) The Kuiper Belt orbital structure by considering the existence of KBPs in the early solar system. The main achievements of last FY 2023 are:
- After thoroughly analyzing the data of the intrinsic Kuiper Belt model, I summarized the main results in a paper by the end of FY2022 and submitted it to a journal with peer review. After a careful revision of the paper, it was published in a high standard peer-reviewed journal in late FY2023 (The Astronomical Journal). At the time of writing this document, this paper has more than 40 thousand downloads, so it is still one of the most popular papers in that journal. In addition, the main results of this study were presented in three national meetings during FY2023.
- I analyzed the simulations of the model of formation of the Kuiper Belt including and not including primordial KBPs. Overall, I found that many systems with KBPs can better explain the Kuiper Belt structure. I am currently summarizing the main results of this model in a new paper planned to be submitted during 2024.
In conclusion, the achievement of the two main goals was obtained by the end of FY2023.
