Abstract:
Although rare, O‐type stars with masses above ~15 times the mass of the Sun affect the interstellar medium (ISM) across a wide range of spatial scales. At small scales, the star’s radiation ionizes the surrounding gas, creating an HII region. At larger scales, the star creates feedback effects, which can affect future star formation. At even larger scales, radiation escaping from HII regions maintains the ionization of diffuse interstellar gas. In this talk, Dr. Luisi will review their current understanding of how massive stars affect their surroundings, and he will present new results from the Stratospheric Observatory for Infrared Astronomy (SOFIA) and the Green Bank Telescope (GBT), bringing us closer to fully understanding the lifecycle of the ISM.
Speaker Bio:
Dr. Matteo Luisi, originally from Graz, Austria, is an Assistant Professor of Physics at Westminster College, where he also manages the College’s planetarium. Prior to his work at Westminster College, he attended West Virginia University for graduate school and as a postdoctoral fellow. Dr. Luisi studies how the most massive stars in our Galaxy interact with their environments through radio and infrared observations.
