On the Low Progenitor Mass of the Binary Pulsar J0737-3039B
Tsvi Piran, Nir J. Shaviv
The observed orbital parameters of the recently discovered binary pulsar J0737-3039 are used to constrain the progenitor system. In particular, the small observed eccentricity and…
Photo-evaporation by thermal winds in dwarf galaxies
Nir J. Shaviv, Avishai Dekel
We revisit the evaporation process of gas from dwarf galaxies after it has been photo-ionized by the UV flux from the first stars and AGNs and heated to T~10^4K or 2x10^4K respecti…
Super Eddington Atmospheres and their Winds
Nir J. Shaviv
We present a model for the steady state winds of super-Eddington systems. These radiatively driven winds are expected to be optically thick and clumpy as they arise from a porous a…
Solution To The Gamma Ray Burst Mystery?
Nir J. Shaviv, Arnon Dar
Photoexcitation and ionization of partially ionized heavy atoms in highly relativistic flows by interstellar photons, followed by their reemission in radiative recombination and de…
On the Source and Location of Temporal Variability in Fireballs
Nir J. Shaviv
Most cosmological models for gamma-ray bursts invoke the production of a ``fireball'' in a compact region, as indicated by the short time variability of the observed GRBs. The high…
