Project Grant 2507891
- 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...
- This National Science Foundation Project Grant award of $444,772 provides funding from September 1, 2022 through August 31, 2025 to study the evolution of magnetic complexity in old sun-like stars under the Mathematical and Physical Sciences program (CFDA 47.049). Principal investigators Metcalfe and Van Saders from the University of Hawaii at Manoa will take polarized spectra of 12 stars using the Potsdam Echelle Polarimetric and Spectroscopic Instrument at the Large Binocular Telescope and the...
- This $462,120 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program supports research to analyze the chemical profiles of dwarf stars and their exoplanets. The primary objectives are to: (a) develop a public, data-driven tool to precisely derive stellar elemental abundances from spectroscopic data; (b) measure elemental abundances for high-priority exoplanet host stars; and (c) produce exoplanetary atmosphere models accounting...
- 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 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 three-year National Science Foundation project grant of $189,753 awarded on September 1, 2022 supports research into the evolution of magnetic complexity in older sun-like stars under the Mathematical and Physical Sciences program (CFDA 47.049). Principal investigators Metcalfe and Van Saders will obtain polarized spectra of 12 stars using the Potsdam Echelle Polarimetric and Spectroscopic Instrument at the Large Binocular Telescope and the Las Cumbres Observatory's Network of Robotic...
- This National Science Foundation (NSF) Division of Astronomical Sciences Project Grant award of $457,353 to The Ohio State University supports a program of data analysis and modeling to interpret the elemental abundance patterns of stars in the Milky Way and its dwarf satellite galaxies. The research, which runs from September 1, 2023 to August 31, 2026, aims to build a coherent picture of the stellar and galactic-scale phenomena that govern the synthesis of chemical elements. This work will...
- The National Science Foundation (NSF) awarded a $714,580 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program to Missouri State University. The grant, titled "RUI: UNDERSTANDING THE CORES OF HORIZONTAL BRANCH STARS VIA MESA, GAIA, AND ASTEROSEISMOLOGY," aims to deepen the understanding of horizontal branch stars, a critical phase in stellar evolution. The research team will use observations and advanced modeling techniques to probe the internal...
- This Project Grant award from the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049) provides $532,746 to the Monterey Institute for Research in Astronomy (MIRA) to investigate anomalous magnetic fields and chemical abundances of Ap/Bp stars. The research aims to develop a homogeneous catalog of these chemically peculiar stars observed by the SDSS/APOGEE survey, analyzing their stellar parameters, chemical compositions, magnetic field...
- The National Science Foundation (NSF) awarded a $227,501 Project Grant under the Mathematical and Physical Sciences federal grant program (CFDA 47.049) to the University of North Georgia (UNG). The grant, which runs from August 1, 2025 to July 31, 2028, will support research to investigate the role of stellar convection zone evolution in creating anomalous rotational evolution epochs in low-mass stars. The research team at UNG, led by the principal investigator, will develop a two-zone stellar...
This Project Grant award, valued at $123,396.00 and spanning September 1, 2025 to August 31, 2028, was provided by the National Science Foundation's (NSF) Division of Astronomical Sciences, under the CFDA program "Mathematical and Physical Sciences." The grant supports collaborative research by The Ohio State University to investigate the rotational evolution and angular momentum transport in K dwarf stars, which exhibit unexpected activity as they age. The research will involve developing new computer models to simulate energy and magnetic field dynamics within these stars, as well as conducting direct measurements of magnetic fields in anomalous K dwarfs using large telescopes. The overarching goals are to address the unexplained rotational and magnetic behavior of these stars, which has important implications for understanding stellar and planetary system evolution. The project also includes an educational outreach component to bring real-world astronomy into classrooms in Hawaii.
