OGLE-2023-BLG-0836L: The sixth microlensing planet in a binary stellar system

Light curves of microlensing events occasionally deviate from the smooth and symmetric form of a single-lens single-source event. While most of these anomalous events can be accounted for by employing a binary-lens single-source (2L1S) or a…
