The formation of Population III binaries from cosmological initial conditions.
Previous high-resolution cosmological simulations predicted that the first stars to appear in the early universe were very massive and formed in isolation. Here, we discuss a cosmological simulation in which the central 50 M(o) (where M(o) is the mass of the Sun) clump breaks up into two cores having a mass ratio of two to one, with one fragment collapsing to densities of 10(-8) grams per cubic...
متن کاملCosmological Formation of Low - Mass
We investigate the early formation of bound objects with masses comparable to the cosmological Jeans mass (10 5 M). We follow the growth of isolated spherically symmetric density peaks starting from the linear perturbative regime. The initial parameters correspond to density peaks of various widths and heights in a cold dark matter cosmology. We use a one-dimensional spherical Lagrangian hydrod...
متن کاملFormation of Early-type Galaxies from Cosmological Initial Conditions
We describe high resolution Smoothed Particle Hydrodynamics (SPH) simulations of three approximately M∗ field galaxies starting from ΛCDM initial conditions. The simulations are made intentionally simple, and include photoionization, cooling of the intergalactic medium, and star formation but not feedback from AGN or supernovae. All of the galaxies undergo an initial burst of star formation at ...
متن کاملFormation of an Early-type Galaxy from Cosmological Initial Conditions?
We describe a high resolution Smoothed Particle Hydrodynamics (SPH) simulation of a spheroidal galaxy starting from ΛCDM initial conditions which is intentionally simple, and includes photoionization and cooling of the intergalactic medium but not feedback from AGN or supernovae. The galaxy undergoes an initial burst of star formation at z ≈ 5, accompanied by the formation of a bubble of heated...
متن کاملLow - Metallicity Star Formation : From the First Stars to
Metal-free stars are assumed to evolve at constant mass because of the very low stellar winds. This leads to large CO-core mass at the end of the evolution, so primordial stars with an initial mass between 25 and 85 M are expected to end as direct black holes, the explosion energy being too weak to remove the full envelope. We show that when rotation enters into play, some mass is lost because ...
