Hello! I'm Yossef Zenati



I'm a theoretical physicist and astrophysicist.
Currently, I am a Ph.D. student at the Physics Department at Technion 
University under the supervision of Prof. Hagai Perets.

I'll be moving to Johns Hopkins University in Baltimore, Maryland, U.S.A in September for a Postdoctoral Fellow.

I study thermonuclear supernovae (Type Ia, Type Ic, Type b/c, ...), both numerically
and analytically. Type Ia supernovae are among the most energetic
and least understood phenomena in the Universe.
I use hydrodynamic simulations to study nuclear burning, turbulent 
nuclear burning, double white dwarf mergers and mergers of other compact 
objects with white dwarfs.


In my free time, I enjoy climbing mountains and urban walls, also 
Science is one of my passions, especially mathematics.


I work on binary systems made of Neutron Stars (NS) and White Dwarfs 
(WD), as well as double White Dwarf systems, and core-collapse of massive, rapidly rotating stars. I study how they form, evolve and merge, and the transient events they produce. I also work on resolving the critical conditions for deflagration and detonation shock waves.
Currently, I am studying turbulent nuclear burning, which can largely enhance nuclear burning rates and may serve as an additional mechanism for stellar explosions. Moreover, it may power thermonuclear and pair-instability supernovae, liberate the neutrinos in core-collapse supernovae, and synthesize r-process heavy nuclei in kilonovae and collapsars.















hypotheses are extensive hydrodynamical, thermonuclear, AMR, multidimensional simulations coupled with detailed nuclear reaction networks ( The computational requirements for these MESA , FLASH). In order to explore a large parameter space of initial conditions. The results of these simulations were followed by an analysis of composition using a large scale nucleosynthetic network – (PPN). These enable us just to calculate the detailed properties of SN’s ejecta. The results of post-processing were also used as an input for modeling the radiative transfer evolution (SuperNu), which is used to provide detailed (light curve/spectra) predictions for the observable properties arising from each theoretical model and chemical composition of SN ejecta.
