 Arend J Poelarends

Arend J. Poelarends, Ph.D.

Associate Professor of Physics and Astronomy

On Faculty since 2011
Science Building 366

Dr. Poelarends’ primary research interest is in computational astrophysics. He grew up in the Netherlands, and holds a Ph.D. from Utrecht University, as well as an M.Div. from Covenant Theological Seminary in St. Louis. As an astrophysicist, he is uniquely qualified to help people answer the significant existential and philosophical questions that modern astronomy presents.

Wheaton College Celebrates Year of "Light"

The United Nations declared 2015 the international year of “light”. The organization is supporting programs all over the world to raise awareness of light-based technologies as well as celebrate noteworthy scientific achievements related to light. Wheaton College is hosting its own light celebration tomorrow afternoon. Dr. AJ Poelarends is a professor of physics and astronomy at Wheaton College. He tells WDCB News Reporter Gary Zidek many people don’t realize the important role light plays in everyday life...

Dr. Poelarends research focuses on the evolution of stars, specifically those between eight to ten times as massive as the sun, i.e. the transition zone between stars that evolve into a white dwarf and stars that explode as a supernova and form a neutron star. He is particularly interested in the later stages of their evolution and uses computational modeling to study their pre-supernova evolution and chemical makeup. These stars could possibly be the birthplace of a significant fraction of the chemical elements in our galaxy (r-process elements), the origin of which we don’t yet know.

In addition to numerical/theoretical research, Dr. Poelarends also uses the new Wheaton telescope to carry out meaningful astronomical observations of objects that are out of reach of amateur telescopes and not important enough for professional telescopes. Currently, he focuses his efforts on the detection of exoplanets. This research resulted in a very fruitful observing campaign during the summer of 2012, in which one of his undergraduate students detected several exoplanets. Possible future areas of research might also be variable stars and asteroids.

The last area of interest is the intersection of science and faith. Dr. Poelarends is particularly interested in the role of worldview stories, and how these shape our identity, our view of God and this reality, and our ethics.
