Projects

Gaia Light Curve Anomaly Detection

Machine learning-based discovery of overlooked variable stars in Gaia DR3.

Key Result: Characterized TIC 22888126 as a dwarf nova with a 57-minute orbital period (below the CV period gap) using TESS archival photometry.

• Method: Isolation Forest anomaly detection on Gaia DR3 light curve statistics
• Data: Gaia DR3 vari_summary, TESS FFI photometry, ROSAT X-ray
• Status: Draft research note ready for submission

See the research note for details.
