Stellar population of the irregular galaxy IC 10 [PDF]
Astronomy Letters, 2009 Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we have performed stellar photometry for several regions of the irregular galaxy IC 10, a member of the Local Group.

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 ...

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 ...

Abundances in dwarf irregular galaxies
Publications of the Astronomical Society of the Pacific, 1986The 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
2011In 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 ...
