Mount Marty College Maderak Publishes Article in Astronomical Journal


Published Date3\7\2014
Mount Marty College assistant professor of physics and mathematics, Dr. Ryan Maderak, recently published an article titled, "Oxygen Abundances of Solar-type Dwarfs in the Hyades and NGC 752" in The Astronomical Journal. The Astronomical Journal is one of the world's top journals on astronomy. Dr. Maderak's article was co-authored with peers from Indiana University and Clemson University.

"Oxygen Abundances of Solar-type Dwarfs in the Hyades and NGC 752" is the first article in a major study of oxygen abundances of star clusters in the Milky Way galaxy. Oxygen is the third most abundant element in the universe (after hydrogen and helium) and can reveal a lot about the chemical history of our galaxy. Star clusters provide a unique way to study the chemical history of the galaxy because the stars in clusters are formed at the same time from the same cloud of gas, and so the age and composition of the cluster can be determined very accurately. It is the goal of the study to learn how the abundance of oxygen has evolved over the history of the galaxy, how star clusters form, and how elements like oxygen are produced by stars.

Dr. Maderak received his Ph.D. from Indiana University and a Bachelor of Science degree from Benedictine College in Kansas.
