Star Formation, Supernovae and the Structure of Disk Galaxies
A physical model for bi-modal star formation and the structure of the interstellar medium and the self-regulating evolution of disk galaxies is presented. Stars heavier than about one solar mass are produced as a result of collisions of molecular clouds or in cloud crushing events whereas low-mass stars are produced at a steady rate in dense molecular clouds and the T-Tauri winds resulting main...
متن کاملGravitational instability and star formation in disk galaxies
We present a general star formation law where star formation rate depends upon efficiency α, timescale τ of star formation, gas component σg of surface mass density and a real exponent n. A given exponent n determines τ which however yields the corresponding star formation rate. Current nominal Schmidt exponent ns for our model is 2 < ns < 3. Based on a gravitational instability parameter QA an...
متن کاملStar Formation in Isolated Disk Galaxies. I. Models and Star Formation Characteristics
We model star formation in a wide range of isolated disk galaxies composed of a dark matter halo and a disk of stars and isothermal gas, using a threedimensional smoothed particle hydrodynamics code. Absorbing sink particles are used to directly measure the mass of gravitationally collapsing gas. They reach masses characteristic of stellar clusters. In this paper, we describe our galaxy models ...
متن کاملStructure and star formation in disk galaxies I. Sample selection and near infrared imaging
We present near-infrared imaging of a sample of 57 relatively large, Northern spiral galaxies with low inclination. After describing the selection criteria and some of the basic properties of the sample, we give a detailed description of the data collection and reduction procedures. The Ks λ = 2.2μm images cover most of the disk for all galaxies, with a field of view of at least 4.2 arcmin. The...
متن کاملStructure and star formation in disk galaxies - III. Nuclear and circumnuclear Hα emission
From Hα images of a carefully selected sample of 57 relatively large, Northern spiral galaxies with low inclination, we study the distribution of the Hα emission in the circumnuclear and nuclear regions. At a resolution of around 100 parsec, we find that the nuclear Hα emission in the sample galaxies is often peaked, and significantly more often so among AGN host galaxies. The circumnuclear Hα ...
