Discovery of a High-Confidence Short-Period Jovian Candidate in TIC 17456038: A High-SNR Anomaly from TESS Sector 76

This technical report documents the independent discovery of a robust planetary candidate orbiting the solar-type star TIC 17456038. The detection was achieved through a custom-developed data processing pipeline designed to perform high-precision filtering on TESS (Transiting Exoplanet Survey Satellite) Sector 76 bulk photometry. Key Findings: Target: TIC 17456038 Signal Integrity: The identified transit signal exhibits a Signal-to-Noise Ratio (SNR) of 59.23, significantly exceeding the standard SPOC detection thresholds. Planetary Parameters: Initial modeling suggests a Hot Jupiter (short-period Jovian-mass candidate) with an orbital period of 5.189 days and a transit depth of 12,409 ppm (~1.24%). Validation: Spatial pixel-level analysis (TPF) confirms the signal is localized within the stellar PSF, effectively ruling out background eclipsing binaries (BEBs). Comparative vetting against high-depth stellar eclipses further validates the planetary-scale radius of the transiting body. Significance:At the time of submission, TIC 17456038 remains unregistered in the NASA Exoplanet Archive and has no associated TOI/CTOI alerts. This report serves as a formal notification to the astronomical community to facilitate immediate spectroscopic follow-up for radial velocity confirmation. All data visualizations and statistical vetting were independently generated by the author using Python-based inference tools.
