Star Formation in Irregular Galaxies

Science, 1989
Irregular galaxies can be viewed as laboratories for studying the processes of star formation. This class of galaxy, unlike the more familiar spiral galaxies, forms stars without spiral arms and does so from a chemically less-evolved interstellar medium.

The stellar structure of irregular galaxies. Face-on galaxies [PDF]

Astronomy Reports, 2005
Stellar photometry of nearby irregular galaxies of the Local Group is used to identify and study the young and old stellar populations of these galaxies. An analysis of the spatial distributions of stars of different ages in face-on galaxies shows that the young stellar populations in irregular galaxies are concentrated toward the center, and form ...

Dwarf Irregular Galaxies

2004
Dwarf irregular galaxies at optical wavelengths are small, faint and appear to be unstructured and irregular in shape. They are typically gas-rich, metal-poor systems, with varying levels of STAR FORMATION occurring in a haphazard manner across the ...

Clumpy Irregular Galaxies

1983
Our planet Earth revolves around the Sun, 150 million kilometers away. Our Sun is just one of the 100 billions or so stars which swarm across our Galaxy, a vast system with diameter around 100 000 light-years.* Our Galaxy is one of the billion other galaxies which our most powerful telescopes are able to detect in the depths of space, at distances up ...

Abundances in dwarf irregular galaxies

Publications of the Astronomical Society of the Pacific, 1986
The results of abundance studies of dwarf irregular galaxies and similar objects are reviewed with special attention to variations in the CNO element group. Observations of the forbidden N II and semiforbidden C III lines in the most metal-poor galaxy known, IZw 18, are presented for the first time and CNO abundances are derived via a photoionization ...

Chemical Evolution of Irregular Galaxies

2011
In this chapter, we describe the properties of irregular galaxies and the proposed chemical evolution models. Irregular galaxies are generally small and rather simple objects with low metallicity and large gas content, suggesting that they are either young objects or have undergone discontinuous star formation activity (bursts) or a continuous but not ...
