The main quest of Farbod’s work is unraveling the chemistry of our nearest stellar neighbors. This includes high-resolution observation and examination of M dwarfs as the most numerous type of star in our Galaxy and the smallest and coolest kind of star on the main sequence. Such an analysis impacts many fields of astrophysics, in particular, the determination of exoplanet radius that depends on a reliable estimate of the host radius that in turn depends on its chemical characteristics. To achieve this goal, Farbod uses high-resolution data from the SPIRou instrument, which is one of the world-leading instruments at the Canada-France-Hawaii telescope. Then he uses chemical spectroscopy methods on the obtained data for the determination of the chemical abundance of different elements in the outer atmosphere of M dwarfs. This will be a critical component for a better understanding of the chemical evolution of M dwarfs and also can heavily contribute to chemical and dynamical improvements of the current synthetic stellar models.
