GalRotpy: a tool to parametrize the gravitational potential of disc-like galaxies

نویسندگان

چکیده

\textbf{GalRotpy} is an educational \verb+Python3+-based visual tool, which useful to undestand how the contribution of each mass component gravitational potential disc-like galaxies by means their rotation curve. Besides, allows user perform a parametric fit given curve, relies on MCMC procedure implemented using \verb+emcee+ package. Here built from Miyamoto-Nagai model for bulge/core and thin/thick disc, exponential together with NFW (Navarro-Frenk- White) or Burkert (cored density profile) Dark Matter halo, where \verb+galpy+ We summarize properties curve involved, then describe along its capabilities. Finally we present characterization two galaxies, NGC6361 M33, show that results M33 provided are consistent those found in literature.

Gravitational instability and star formation in disc galaxies

We present a general star formation law in which the star formation rate depends upon the ef®ciency a and the time-scale t of star formation, and the gas component jg of the surface mass density. The current nominal Schmidt exponent nS for our model is 2 < nS < 3. Based on a gravitational instability parameter QA and another dimensionless parameter fP ˆ …P=Gj 2 c† , where P ˆ pressure and jc ˆ ...

A Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope

In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...
