- This federal Project Grant award from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) will support a collaborative research effort between Georgia State University, Bridgewater State University, and Southern Connecticut State University. The $399,130 award, effective September 1, 2025 through August 31, 2028, will fund a project to observe a sample of nearly 5,000 nearby stars using speckle imaging techniques. The observations will focus on K dwarf...
- This National Science Foundation (NSF) award under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049) provides $365,771 to the University of California, Santa Cruz (UCSC) to enhance stellar models by simulating turbulent plasma flows within stars using cutting-edge computational tools. The project aims to refine the understanding of rotational mixing within stars, a key factor in stellar evolution codes, through direct numerical simulations and multiscale asymptotic...
- The National Science Foundation awarded a $300,000 project grant under the Mathematical and Physical Sciences program to investigate magnetism and rotation in ultracool dwarfs and the smallest stars. With a completion date of November 2024, this funding will support research examining these phenomena in astronomical bodies through the lens of the Mathematical and Physical Sciences program's goal of strengthening the nation's scientific enterprise by increasing knowledge and understanding of...
- This Project Grant award of $118,673 from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research project focused on "Polarimetric Asteroseismology of Massive Hot Stars." A team of astronomers from the Monterey Institute for Research in Astronomy, Florida Gulf Coast University, SETI Institute, University of Maryland Baltimore County, and University of Wisconsin-Madison, along with international partners, will...
- The University of Hawaii at Manoa was awarded a $697,010 Project Grant from the National Science Foundation under the Mathematical and Physical Sciences program (CFDA 47.049). The grant will fund the "CATCH A FADING STAR: USING TRANSIENT DIMMING TO EXPLORE THE PLANET-FORMING ZONES OF YOUNG STARS" research project being conducted from September 2021 through August 2024. The project aims to use observations of temporary dimming events caused by dust clouds around young stars to explore...
- This Project Grant award of $237,593 from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) will fund a collaborative astronomical research project between Georgia State University, Bridgewater State University, and Southern Connecticut State University. The project will conduct speckle imaging observations of approximately 5,000 nearby stars within 40 parsecs of the Sun, focusing on K and M dwarf stars. This will enable the researchers to study the...
This $524,548 Project Grant award from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) will support a collaborative research project on rotational evolution and angular momentum transport in K dwarf stars. The project will develop new computer models to understand why certain K dwarf stars (with temperatures between 3,900-5,300 K) display unexpected rotational behavior and persistent magnetic activity as they age, in contrast with the expected slower spin-down of stars like our Sun. The research will combine advanced internal angular momentum transport models with observational data, including direct measurements of magnetic field strength and topology in K dwarfs using large telescopes. The overarching goals are to advance scientific understanding of stellar aging processes and support science education outreach in Hawaii. The award has a performance period from September 1, 2025 to August 31, 2028 and is led by the University of Hawaii at Manoa.
