Astronomer to talk about spiral galaxies


Dr. Rene Pierre Martin will discuss the importance of barred spirals objects in spiral galaxies at 6 p.m. March 2 at the Visitor Information Station on Mauna Kea.

In this presentation, he will review some of the early history of observations of spiral galaxies, including some of the first descriptions of galaxies with bars. Then, he will review how bars can be formed, how they evolve and how they might considerably affect the evolution of their host galaxies.

Martin will also explain that some galaxies have more than one bar and that the Milky Way is, in fact, a barred spiral.

He will briefly describe an ambitious project to be undertaken with an innovative instrument at CFHT on Mauna Kea next year, aiming in better understanding of the significance of bars in galaxies.
