Hi!
I am Özgün, a PhD candidate at the Leibniz Institute for Astrophyiscs (AIP), working within Stellar Activity Group. My research lies in observational stellar astrophysics, with a focus on stellar activity in binary star systems and the interactions with their close companions. My primary focus is on RS CVn-type close binaries—subgiant or giant stars paired with a companion, exhibiting enhanced levels of chromospheric activity. I analyze time-series and high-resolution spectroscopic data to study stellar surface structures, radial velocities, magnetic fields, and chromospheric activity indicators, exploring how these properties are interrelated. I am particularly interested in reconstructing the three-dimensional characteristics of stellar systems to gain a deeper understanding of the observable connections between orbital dynamics and stellar rotation.
I completed my undergraduate studies at Bogazici University in Istanbul. I then pursued a Master’s degree at the University of Potsdam, where I conducted my thesis within the Solar Physics Group. My thesis focused on center-to-limb variations of solar chromospheric spectral lines, based on observations carried out at the historic Solar Observatory Einstein Tower.
