Project Grant 2511209
- This $363,623 Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049), supports a collaborative research effort between the City University of New York Queens College and Penn State Scranton. The primary objective is to develop and apply a new "seismic technique" that combines precision measurements of pulsating white dwarf stars with Gaia parallax data to accurately determine their masses and effective...
- The National Science Foundation (NSF) awarded a $390,073 Project Grant under the Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049) to the University of Oklahoma (OU) to study the origins and evolution of ultramassive white dwarfs - the dense, Earth-sized remains of stars like our Sun. The 3-year project aims to characterize the mass and temperature distribution of the most massive white dwarfs, identify likely white dwarf merger remnants, analyze massive pulsating white...
- This federal Project Grant award of $232,034 from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) will fund a theoretical investigation into helium-ignited binary white dwarf mergers as progenitors of Type Ia supernovae. The research team at the University of Massachusetts Dartmouth will employ state-of-the-art 3D hydrodynamic simulations to study the evolution, detonation, and observable signatures of these stellar events. The project will utilize...
- 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...
- This federal Project Grant award, totaling $145,866, was provided by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) to the University of Chicago. The funding will support a collaborative research project to study the internal structures of massive hot stars, the greatest sources of energy and new material in the galaxy, through the application of a new technique called polarimetric asteroseismology. The research team, comprised of astronomers...
- 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...
- The University of Oklahoma received a $368,640 Project Grant award from the National Science Foundation Division of Astronomical Sciences under the Mathematical and Physical Sciences federal grant program (CFDA 47.049). The grant will fund research services focusing on constraining the evolutionary pathways of white dwarfs through crystallization studies, investigations into cooling anomalies, and analyses of white dwarf mergers. Products and services to be delivered include a new...
- This Project Grant award, valued at $496,984.00 and provided by the Division of Astronomical Sciences, a civilian agency within the National Science Foundation (CFDA 47.049 - Mathematical and Physical Sciences), will support research on hypervelocity white dwarfs that survive thermonuclear supernovae. The primary objectives of the project are to constrain the progenitor channels of Type Ia supernovae by identifying and characterizing these fast-moving stellar remnants, which provide direct...
- 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...
- The National Science Foundation (NSF) Division of Astronomical Sciences awarded a $447,242 Project Grant to The Washington University in St. Louis to conduct research on the multi-wavelength emission of pulsars. The 3-year grant, awarded on September 1, 2023, will support a research team using direct numerical simulations to develop a unified theoretical model connecting plasma physics processes to observational data on these rapidly rotating, highly magnetized neutron stars. The research aims...
This federal Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) provides $269,197 to Iowa State University of Science and Technology to study the puzzling behavior of pulsating white dwarf stars. The project aims to use computer models to understand the causes of phenomena such as sudden outbursts and random changes in brightness observed in these stars as they cool, as well as why pulsations cease. The award will support a comprehensive theoretical investigation and train two graduate students and involve undergraduates in astrophysics research. Key activities include generating evolutionary models, performing linear adiabatic and nonadiabatic pulsation calculations, and analyzing amplitude coherence and resonant coupling to test potential mechanisms for suppressing observable pulsations or triggering episodic outbursts. The project runs from September 1, 2025 to August 31, 2027.
