Computation plays a big part of astronomy research at IU, all the way from massive N-body calculations and analysis of very large datasets to our day-to-day desktop manipulations. Fortunately, IU provides the computational resources to make all this possible.
Observing the surface abundances of Li, Be, and B in stars helps us understand the physical processes occurring inside stars. These fragile elements survive only in the outermost layers of stars, and thus their surface abundances trace interior processes that connect to the surface.
Roughly 5000 "exoplanets" (planets orbiting other stars outside the Solar System) have been discovered, and that number is growing rapidly each year.
IU Astronomers actively explore how galaxies have evolved through the history of the Universe, focusing both on star formation and chemical abundances.
Astronomers make use of wide regions of the electromagnetic spectrum for observations, including ultraviolet, optical, infrared, and radio light.
Indiana University astronomers have begun to explore the bulge of stars in the heart of our Milky Way using a new survey of 250 million stars imaged with the Dark Energy Camera on the Blanco Telescope in Chile.
