Irradiated Protoplanetary Disks:
Chemical Models and ALMA Observations
Georgia Clickner (CAS and UVA)
Next CAS Meeting
Wednesday, September 2nd at 7 pm
at Leander McCormick Observatory -
Abstract:
Most stars, and as a result planets, form within stellar clusters and therefore are
influenced by UV fields from nearby massive stars. It is believed that intermediate UV fields, which have a strength lower than the Orion Nebula Cluster but higher than nearby low mass star forming regions, are the most common. In fact, it is thought that our own solar system originated in one of these intermediate UV environments. Gaining a deeper understanding of the effects of these UV fields on stellar systems can provide insight into disk and planet formation, however there is still much to learn about how different levels of UV fields influence this process. In this talk, Georgia will delve into our current understanding of this process, using recent observational results from her 2026 VICO summer internship and chemical models from an ongoing research project. -
CV:
Georgia is a 2nd year astronomy-physics major at the University of Virginia. In the past year, her research has mainly focused on understanding the effects of external irradiation on protoplanetary disks. She is also an active member of the Occultation Group at UVA and where she currently holds the position of editor in the group. Additionally, Georgia has been a member of CAS since her junior year of high school and now serves as the club’s secretary.
