DESCRIPTION:Title: Measuring magnetic field strengths in M dwarfs (Licent
 iate defence) Speaker: Irene AmateisAffiliation: Uppsala UniversityRoom

 the Galaxy and important targets in the search for potentially habitable e
 xoplanets. Their strong magnetic fields shape stellar atmospheres and infl
 uence the environmentsof their orbiting planets\, making reliable magnetic
  field measurements essential.This licentiate thesis investigates the reli
 ability of magnetic field measurements in M dwarfs using Zeeman broadening
  in high-resolution spectra. By testing commonly used diagnostic methods a
 gainst syntheticspectra generated from magnetohydrodynamic simulations\, w
 e show that some methods can underestimate magnetic field strengths by up 
 to 50%\, while alternative approaches provide a more accurate recovery of 
 the true field strength. These results establish quantitative benchmarksf
 or interpreting magnetic field measurements from intensity spectra and hig
 hlight important limitations of commonly used diagnostics. As a next step\
 , the most reliable methods will be applied to observations of M dwarfs ob
 tained with the CRIRES+ spectrographat the VLT. The external reviewer is
