Stars are among the most numerous objects in the Cosmos, and are the primary objects that make the bulk of larger structures we observe. They are born together, and consequently evolve together, often interacting with a close companion over the course of their lives, or interacting dynamically with many other stars in the dense stellar environments in which they are found. These interactions have profound influence on the long term evolution of stars. In CIERA, we consider numerical and theoretical models of stellar interactions and use them to understand and explain observations of stars across the Milky Way, and in dense stellar systems.

Research at CIERA

The centers of galaxies are complex environments whose properties are a result of the interactions between the massive black holes that reside there, vast clouds of gas, and dense populations of stars and stellar remnants.

Professor Rasio’s group studies numerical models of dense stellar environments such as nuclear star clusters.

Professor Larson’s group studies the interactions of single stars with massive black holes, a prospective LISA gravitational wave source class known as an EMRI (“extreme mass ratio inspiral”).

Professor Zadeh is an observer who studies stellar populations and physical processes in the Milky Way nucleus using observations across the electromagnetic spectrum.

High School Summer Research Experience in Astronomy at Northwestern

Deadline: 11:59pm, May 31, 2019

CIERA is pleased to announce the Summer Research Experience in Astronomy at Northwestern for high school students during Summer 2019. This highly-interactive, small-cohort program provides exposure to real astronomy research experiences in an atmosphere of team-style learning, hands-on training, and individual mentorship and advising. Students enrolled in the research experience program will take computer programming
