We study the properties (density, total gas+stars mass, stellar mass, velocity dispersion, and star formation rate) of the cloud hosting the first local, isolated "star formation" event in the simulation and compare them with those of the cloud formed by a later central, global collapse ...
In this work, the gas infall and the formation of outflows around low- and high-mass protostars are investigated. A radial self-similar approach to model the transit of the molecular gas around the central object is employed. We include gravitational and radiative fields to produce heated pres...
Stars with an initial mass on the Zero Age Main Sequence above 8 M⊙are considered to be high mass stars. They evolve in a short timescale (<25 Myr) by nuclear fusion of successively all available...Prantzos, NikosSpringer Berlin Heidelberg...
Knowledge of the fundamental stellar properties: mass, radius, effective temperature and wind mass-loss rate are essential for constraining models of the late stages of evolution. The only accurate, fundamental method is to determine these parameters from binary stars but this has been done for few...
Even though a high mass star has more total fuel at the beginning of its life, it has a shorter lifespan than a low-mass star. This is because the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our exp...
<italic>Context. </italic>Water probes the dynamics in young stellar objects (YSOs) effectively, especially shocks in molecular outflows. It is therefore a key molecule for exploring whether the physical properties of low-mass protostars can be extrapola
On the high-mass side of the gap are dwarf elliptical (dE) galaxies that are dominated by stars in their inner regions. While the low-mass side includes dwarf spheroidal (dSph) galaxies that are dark matter dominated and ultracompact dwarf (UCD) objects that are star-dominated. Evolutionary ...

When did galaxies start forming stars? What is the role of distant galaxies in galaxy formation models and the epoch of reionization? What are the conditions in typical star-forming galaxies at redshifts≳4? Why is galaxy evolution dependent on environment? The Spitzer Space Telescope has been...
How high-mass stars formAn infrared images of the W# region of the Perseus Arm of the Milky Way Galaxy is presented from the European Space Agency's Herschel Space Observatory, which shows star-formation regions where...
