This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program, with a total funding amount of $441,642, supports research to deepen the understanding of the final stages of stellar evolution, specifically focusing on red giants and their mass-shedding processes. The key objectives of this 2-year research project, which runs from September 1, 2024 to August 31, 2026, are to: Employ very long baseline interferometry (VLBI) observations, including measurements at unprecedented frequencies above 200 GHz, to map the regions where stellar winds are launched from red giants, particularly using SiO maser lines. This will provide high-resolution spatial data (10-500 microarcseconds) essential for understanding the mechanisms driving these winds, which are major contributors to galactic enrichment with heavy elements and dust. Develop advanced data processing techniques and calibration methods tailored for high-frequency VLBI observations, and share these innovations with the broader scientific community to enhance capabilities for studying complex astrophysical phenomena. Produce two podcast episodes to broaden public understanding of stellar evolution and its implications, featuring project updates and interviews with the research team. The award will provide training opportunities for undergraduate students and a postdoctoral researcher, fostering the next generation of scientific talent in this critical area of astrophysics research.
