Star formation in N-body simulations I. The impact of the stellar ultraviolet radiation on star formation
We present numerical simulations of isolated disk galaxies including gas dynamics and star formation. The gas is allowed to cool to 10 K, while heating of the gas is provided by the far-ultraviolet flux of all stars. Stars are allowed to form from the gas according to a Jeans instability criterion: gas is unstable when the Jeans mass is smaller than a critical mass, and stars form as soon as th...
متن کاملStar Formation and System Calibration
Large scale star formation and chemical evolution are studied in the Bar of the LMC. For our programme, we use the HST Wide Field Planetary Camera and uvby photometry. This calls for careful calibration of the HST WFPC2 uvby system. Such calibration is derived through observations of cluster fields with both large ground based telescopes, including generous amounts of standard stars, and with t...
متن کاملStar Formation: Lessons from Taurus
The Taurus molecular cloud complex is the paradigm for quiescent, low-density, isolated star formation. Yet the age distribution of its stellar population indicates that star formation is a rapid and dynamic process, inconsistent with the old picture of magnetically-controlled protostel-lar cloud collapse. Instead, Taurus seems to have formed stars in a manner qualitatively consistent with the ...
متن کاملStar Formation from Turbulent Fragmentation
Star formation is intimately linked to the dynamical evolution of molecular clouds. Turbulent fragmentation determines where and when protostellar cores form, and how they contract and grow in mass via accretion from the surrounding cloud material. Efficiency, spatial distribution and timescale of star formation in turbulent clouds are estimated by comparing numerical models of self-gravitating...
متن کاملStar Formation Efficiencies and Star Cluster Formation
Starbursts produce large numbers of Young Star Clusters (YSCs). Multi-color photometry in combination with a dedicated SED analysis tool allows to derive ages, metallicities, EB−V, and masses including 1σ uncertainties for individual clusters and, hence, mass functions for YSC systems. The mass function, known to be Gaussian for old Globular Cluster (GC) systems, is still controversial for YSC ...
