Abstract

I will work under the supervision of Prof. Dr. Laurent Loinard, an expert in high-precision astrometry, to reduce and analyze multi-epoch continuum observations of HL Tauri. The methodology includes data retrieval from major radio archives, calibration using specialized scripts developed by Loinard's group, astrometric corrections for proper motions, and orbital analysis using tools like orbitize!. The same techniques will be applied to the nearby source XZ Tauri to study the internal dynamics of the L1551 cloud region.
