The S2 orbit and tidally disrupted binaries: indications for collisional depletion in the Galactic center
Yotam Ashkenazy, Shmuel Balberg
The properties of the stellar cluster surrounding Sagittarius A* can be assessed indirectly through the motion of the S-stars. Specifically, the current accuracy to which the progr…
The non-equilibrium Marshak wave problem in non-homogeneous media
Nitay Derei, Shmuel Balberg, Shay I. Heizler +3
We derive a family of similarity solutions to the nonlinear non-equilibrium Marshak wave problem for an inhomogeneous planar medium which is coupled to a time dependent radiation d…
The Primary Flare Following a Stellar Collision in a Galactic Nucleus
Yuval Brutman, Elad Steinberg, Shmuel Balberg
High-velocity stellar collisions near supermassive black holes may result in a complete disruption of the stars. The initial disruption can have energies on par with supernovae and…
Segregation and Collisions in Galactic Nuclei: Rates of Destructive Events Near a Supermassive Black Hole
Shmuel Balberg
The centers of galaxies host a supermassive black hole surrounded by a dense stellar cluster. The cluster is expected to develop mass segregation, in which gravitational scattering…
Solutions of the converging and diverging shock problem in a medium with varying density
Itamar Giron, Shmuel Balberg, Menahem Krief
We consider the solutions of the Guderley problem, consisting of a converging and diverging hydrodynamic shock wave in an ideal gas with a power law initial density profile. The se…
Stellar Collisions in Galactic Nuclei: Impact on Destructive Events Near a Supermassive Black Hole
Shmuel Balberg, Gilad Yassur
Centers of galaxies host both a supermassive black hole and a dense stellar cluster. Such an environment should lead to stellar collisions, possibly at very high velocities so that…
