A Test of Star Formation Laws in Disk Galaxies
We use observations of the radial profiles of the mass surface density of total, Σg, and molecular, ΣH2, gas, rotation velocity and star formation rate surface density, Σsfr, of the molecular dominated regions of 12 disk galaxies from Leroy et al. to test several star formation laws: a “Kennicutt power law”, Σsfr = AgΣ 1.5 g,2; a “Constant molecular law”, Σsfr = AH2ΣH2,2; the “Turbulence-regula...
متن کاملStar Formation in Isolated Disk Galaxies. Ii. Schmidt Laws and Efficiency of Gravitational Collapse
We model gravitational instability in a wide range of isolated disk galaxies, using GADGET, a three-dimensional, smoothed particle hydrodynamics code. The model galaxies include a dark matter halo and a disk of stars and isothermal gas. Absorbing sink particles are used to directly measure the mass of gravitationally collapsing gas. Below the density at which they are inserted, the collapsing g...
متن کاملThe star formation law in disk galaxies: a Bayesian view
The dependence of the star formation rate Ψ ∝ g/r on gas surface density g and galactocentric radius r are studied in disk galaxies. The sample includes the Milky Way galaxy and 11 nearby Sb and Sc galaxies with known radial gas surface densities and Hα surface brightnesses, used as a measure of the SFR. The Bayesian approach permits to compute genuine probabilities for the validity of several ...
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 Modes in Low - Mass Disk Galaxies
Low-mass disk galaxies with well-organized structures are relatively common in low density regions of the nearby Universe. They display a wide range in levels of star formation activity, extending from sluggishly evolving 'superthin' disk systems to nearby starbursts. Investigations of this class of galaxy therefore provides opportunities to test and define models of galactic star formation pro...
