Untangling the Magnetic Puzzle of HD 169142: Clues from a Young Star Hosting Planets

This study explores the magnetic field of HD 169142, a young star with a planet-forming disk. Using polarized light data, the authors detect complex magnetic features likely influenced by both the stellar surface and surrounding gas. Variability in hydrogen lines and elemental spots suggests a dynamic magnetosphere. The findings point to intricate star-disk interactions and highlight the need for further magnetic mapping.
