Star Formation Rates in Spheroids¶
Class providing models of the star formation rate (in \(\mathrm{M}_\odot\) Gyr\(^{-1}\)) in the spheroid (bulge) component of a galaxy. Star formation in spheroids is typically triggered by galaxy mergers or disk instabilities that funnel gas into the galactic center. Implementations commonly adopt a timescale approach in which the star formation rate is proportional to the available cold gas mass divided by a dynamical or depletion timescale.
Default implementation: starFormationRateSpheroidsTimescale
Methods¶
rate→double precisionReturns the rate (in units of \(\mathrm{M}_\odot\) Gyr\(^{-1}\)) for star formation in the spheroid component of
node.type(treeNode), intent(inout), target :: node
starFormationRateSpheroidsCentralsOnly¶
A star formation rate in galactic spheroids which sets rates in satellites to zero.
starFormationRateSpheroidsTimescale¶
A star formation rate in galactic spheroids which computes the rate by integrating a star formation rate over the spheroid.
