Biographical Information:

Professor Lugger has been on the IU Astronomy faculty since 1984. She received an A. B. in Astronomy in 1976, an A. M. in Astronomy in 1981, and a Ph.D. in Astronomy in 1982 from Harvard University. She was a postdoctoral fellow at Northwestern University and the University of Illinois at Urbana-Champaign and an Assistant Professor at the University of Missouri, Columbia before coming to IU. Professor Lugger typically teaches A105 (Stars and Galaxies).

Research Interests:

Professor Lugger studies the dynamics of stellar systems (globular star clusters, interacting binary stars, galactic nuclei and clusters of galaxies). Professors Phyllis Lugger and Haldan Cohn  lead a research program in this area which includes both observational and theoretical investigations. Their research uses the WIYN telescope, the Hubble Space Telescope the Chandra X-ray Observatory and high performance supercomputers at IU. Current studies include:

  • ChaMPlane survey: WIYN Hydra spectroscopy of galactic plane x-ray sources
  • Globular Clusters: WIYN and HST studies of cluster structure and dynamics, HST and Chandra studies of binary x-ray sources in clusters
  • N-body supercomputer simulations of the dynamical evolution of globular star clusters
  • Astronomy 105: Stars and Galaxies 
  • Astronomy 102: Gravity, the Great Attractor: the Evolution of Planets, Stars and Galaxies
Research collaborators:

Josh Grindlay (Harvard University), Charles Bailyn and Gordon Drukier (Yale University), Adrienne Cool (San Francisco State University) and Brian Murphy (Butler University)

Former Ph.D. students:

Steve Cederbloom (Mount Union College), Robert Grabhorn , Paul Bode (Princeton University), Jim Dull (Albertson College of Idaho), Bob Berrington (Ball State), Shawn Slavin (Purdue-Calmet), and Allen Rogel (Bowling Green State).
