Upper Limits on Trojan Companions Around Four Ultra-Hot Jupiters from TESS - Analysis Code and Data

Analysis code and results for a systematic search for Trojan companions at the L4 and L5 Lagrange points of four ultra-hot Jupiter systems using TESS photometry. This repository contains:- Python analysis pipeline (trojan_exoplanet_search.py)- RNAAS manuscript (LaTeX source)- Results figures for TOI-1431 b and WASP-189 b- Complete documentation and dependencies Targets analyzed:1. TOI-2109 b (P=0.67 days, T_eq=3500 K)2. HAT-P-7 b (P=2.21 days, T_eq=2200 K)3. TOI-1431 b (P=2.65 days, T_eq=2400 K)4. WASP-189 b (P=2.72 days, T_eq=3435 K) Results: No significant Trojan detections at either L4 or L5 Lagrange points. Upper mass limits: 0.5-0.8 Earth masses (3σ), representing 0.03-0.05% of planetary masses. Related publication: Saxena, A. (2026).
