Protostellar mass accretion rates from gravoturbulent fragmentation
We analyse protostellar mass accretion rates Ṁ from numerical models of star formation based on gravoturbulent fragmentation, considering a large number of different environments. To within one order of magnitude, Ṁ ≈ MJ/τff with MJ being the mean thermal Jeans mass and τff the corresponding free-fall time. However, mass accretion rates are highly timevariant, with a sharp peak shortly after th...
متن کاملProtostellar angular momentum evolution during gravoturbulent fragmentation
Using hydrodynamic simulations we investigate the rotational properties and angular momentum evolution of prestellar and protostellar cores formed from gravoturbulent fragmentation of interstellar gas clouds. We find the specific angular momentum j of molecular cloud cores in the prestellar phase to be on average 〈 j〉 = 7 × 1020 cm2 s−1 in our models. This is comparable to the observed values. ...
متن کاملThe Formation of the First Stars I. Mass Infall Rates, Accretion Disk Structure and Protostellar Evolution
We present a theoretical model for primordial star formation. First we describe the structure of the initial gas cores as virialized, quasi-hydrostatic objects in accord with recent high resolution numerical studies. The accretion rate can then be related to characteristic densities and temperatures that are set by the cooling properties of molecular hydrogen. We allow for rotation of the gas c...
متن کاملThe Formation of Stellar Clusters: Time Varying Protostellar Accretion Rates
Identifying the processes that determine strength, duration and variability of protostellar mass growth is a fundamental ingredient of any theory of star formation. I discuss protostellar mass accretion rates Ṁ from numerical models which follow molecular cloud evolution from turbulent fragmentation towards the formation of stellar clusters. In a dense cluster environment, Ṁ is strongly time va...
متن کاملTheory of Protostellar Accretion
This paper reviews current theoretical work on the various stages of accretion in protostars, and the relationship of these ideal stages to the spectral classes of observed protostellar systems. I discuss scaling relationships that have been obtained for models of pre-stellar cores as they evolve by ambipolar diffusion toward a central singularity, and expectations for the dynamical evolution a...
