Star Formation and Abundances in S0 Galaxies
A significant number of S0 galaxies with a detectable ISM show some level of on-going massive-star formation activity in the form of visible H II Regions. A rich ISM, however, does not guarantee star formation: a significant number of relatively gas-rich S0s have no detectable H II regions down to the level of regions ionized by single O stars (e.g., Orion-like H II regions). The Hα luminositie...
متن کاملStar-forming accretion flows and the low luminosity nuclei of giant elliptical galaxies
The luminosities of the centers of nearby elliptical galaxies are very low compared to models of thin disc accretion to their black holes at the Bondi rate, typically a few hundredths to a few tenths of a solar mass per year. This has motivated models of inefficiently-radiated accretion that invoke weak electron-ion thermal coupling, and/or inhibited accretion rates due to convection or outflow...

متن کاملStar-forming Complexes in Galaxies
Star complexes are the largest globular regions of star formation in galaxies. If there is a spiral density wave, nuclear ring, tidal arm, or other welldefined stellar structure, then gravitational instabilities in the gaseous component produce giant cloud complexes with a spacing of about three times the width. These gas complexes form star complexes, giving the familiar beads on a string of s...
متن کاملSingle star-forming galaxies and star-forming galaxies in SF + SF and mixed pairs
We compare the SFR of single star-forming galaxies with the SFR of star-forming galaxies in pairs. Volume-limited samples are compared selected from the 2dFGRS, applying a maximum magnitude difference criterion. We show that SF galaxies in SF + SF pairs typically increase their SFR as they get fainter, whereas this does not happen for SF galaxies in mixed (SF + passive) pairs. And we provide ev...
