  New Light on Old Stars in the Era of James Web Space Telescope

  Roman Gerasimov, Ph.D.
  Wednesday December 4th 2024 - 6:30 pm ET
  Leighton Auditorium, Main Branch, St. Joseph County Public Library

  The chemical diversity of the universe that makes our own existence possible is owed to multiple generations of stars that converted the primordial soup of hydrogen and helium into the periodic table we know today. To understand this process, Roman Gerasimov looks for the oldest objects in our galaxy that formed shortly after the beginning of time and preserve the fossilized record of the early universe in their chemical composition. The new generation of observatories, including the James Webb Space Telescope, now provide a deeper look into our cosmic history than ever before. In this talk, Gerasimov invites you to join him in his search for the oldest stars in the least explored corners of our galaxy, and the chemical secrets they contain within.
