Dr. Zsolt Keszthelyi

My name is Zsolt Keszthelyi and I am currently a postdoctoral project research fellow at the Center for Computational Astrophysics, Division of Science at the National Astronomical Observatory of Japan.
I develop software and perform numerical simulations on high-performance computing clusters. I leverage data-driven insights and collaborate with international teams.

Magnetism is a general property of astrophysical plasmas. I wrote a review paper on "Magnetism in High-Mass Stars". The article is open-access, please find it here: Review Article.

Very Massive Stars are amongst the most exciting objects in the Universe. See our paper here. A Zenodo record (with models and codes) is available here.

Surface fossil magnetic fields have a strong impact on stellar mass loss and rotation and, as a consequence, on the evolution of massive stars. See our papers here:
Paper I, Paper II, Paper III, Paper IV, and Paper V. Zenodo records are available here, here, here, here (including an open-source library of over 8,000 stellar evolution and 24,000 stellar structure models), and here.

The RAMBO project is a long-term campaign to observe hot star magnetospheres in radio frequencies and describe their physical properties. See our first paper here.

The magnitude and time evolution of mass-loss rates significantly affect the nature and final fate of massive stars. See our paper here. A Zenodo record is available here.
