معرفی
Dr. Jonas Klevas is a Researcher at the Institute of Theoretical Physics and Astronomy (ITPA) within Vilnius University's Faculty of Physics, specializing in stellar astrophysics with particular expertise in stellar atmospheres and related phenomena.
His research focuses on:
- Stars: atmospheres and late-type stellar characteristics
- Elemental abundances in various stellar environments
- Convection processes and hydrodynamics in stellar atmospheres
- Radiative transfer mechanisms
Dr. Klevas's work centers on three-dimensional hydrodynamical modeling of stellar atmospheres using the CO5BOLD code, with emphasis on red giant stars. His research investigates elemental abundances (lithium, sodium, magnesium, potassium, and oxygen) in Galactic globular clusters and metal-poor stars through detailed spectral analysis. He has published multiple papers in Astronomy & Astrophysics examining how convection and non-local thermodynamic equilibrium (NLTE) effects influence spectral line formation.
Dr. Klevas actively contributes to the astronomical community through his service roles as Reviser of the Lithuanian Young Scientist Union and Member of the Board of the Lithuanian Astronomical Union. He also participates in science popularization activities, with content available through Lithuanian technology media outlets.
