Formation and early evolution of stellar clusters

2021
We describe a novel numerical method for the studying the formation and evolution of stellar clusters, Torch. This method combines the magnetohydrodynamics code Flash with the Astrophysical Multipurpose Software Environment, AMUSE. Once embedded into AMUSE, we combine Flash with the stellar evolution code SeBa, the N-body dynamics code ph4 and the ...

Early stellar evolution

Publications of the Astronomical Society of the Pacific, 1994
Research into the formation and early evolution of stars is currently an area of great interest and activity. The theoretical and observational foundations for this development are reviewed in this paper. By now, the basic physics governing cloud collapse is well understood, as is the structure of the resulting protostars.

Herbig-Haro Flows: Probes of Early Stellar Evolution

Annual Review of Astronomy and Astrophysics, 2001
▪ Abstract  Outflow activity is associated with all stages of early stellar evolution, from deeply embedded protostellar objects to visible young stars. Herbig-Haro (HH) objects are the optical manifestations of this powerful mass loss. Analysis of HH flows, and in particular of the subset of highly collimated HH jets, provides indirect but important ...

Mass loss in early stages of stellar evolution

Nature, 1976
IT has been known for some time that stars lose mass between their birth on the main sequence and their death as white dwarfs (or as neutron stars or black holes for more massive stars), and the existence of the solar wind shows that not all the mass loss occurs in a last gasp to form a planetary nebula.

Probing the Early Chemical Evolution of the Sculptor dSph With Purely Old Stellar Tracers [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2016
Abstract We present the metallicity distribution of a sample of 471 RR Lyrae (RRL) stars in the Sculptor dSph, obtained from the I-band period–luminosity relation. It is the first time that the early chemical evolution of a dwarf galaxy is characterized in such a detailed and quantitative way, using photometric data alone.

Fossil fields in early stellar evolution

Proceedings of the International Astronomical Union, 2008
AbstractFavored explanations for the presence of magnetic fields on CP stars and the presence of the solar tachocline below the convection zone both imply fossil magnetic fields in the radiative zones. The initial, convective evolution of magnetic fields in a proto-star is studied by numerical, global simulations. The computations are to be extended by
