Project Grant 2511139
- This National Science Foundation (NSF) Project Grant award under the Mathematical and Physical Sciences program (CFDA 47.049) provides $253,363 to study the common envelope evolution process in binary star systems. The investigators will use telescopes and computer simulations to observationally map the initial and final conditions of this poorly understood but common stellar phenomenon. They will characterize a benchmark set of 52 high-probability post-common envelope binary systems located...
- The National Science Foundation (NSF) Division of Astronomical Sciences awarded a $377,610 Project Grant to the University of Illinois to conduct research on common envelope evolution and the origins of massive compact binaries. Through this 3-year grant, the Principal Investigator (PI) and team will use 3D radiation-hydrodynamic simulations to study the evolution of common envelope binaries comprised of a red supergiant and a neutron star or black hole companion. The research aims to address...
- This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) provides $483,886 to the University of California, San Diego (UCSD) to conduct research on binary star formation in the Orion Nebula Cluster. The research aims to use advanced techniques like laser frequency comb spectroscopy and adaptive optics to discover a larger population of close binary stars that were previously undetected in this stellar nursery. The findings...
- This federal Project Grant award, issued by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) program, will enhance existing search strategies and analysis capabilities for discovering and characterizing the coalescence of compact binary systems, such as black holes and neutron stars. The $200,000 award, with a performance period from August 1, 2024 to July 31, 2027, will fund four key activities: (i) extending multi-messenger Bayesian inference...
- This $244,369 Project Grant awarded by the National Science Foundation's Mathematical and Physical Sciences program supports research to identify and characterize populations of massive stellar binary systems, composed of a black hole or neutron star and a massive star, in nearby low-metallicity dwarf galaxies. The project will use multiwavelength archival data to study these "high mass X-ray binaries" as analogs to similar systems that may have formed in the early universe....
- The National Science Foundation (NSF) awarded a $240,810 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) federal grant program to Carnegie Mellon University. The grant supports a collaborative research project titled "Near Field Population Synthesis - The Final Stages in the Evolution of the Most Massive Stars". The project aims to constrain key uncertainties in the evolution of massive stars, such as mass loss efficiency and supernova impacts, by precisely...
- This National Science Foundation (NSF) Mathematical and Physical Sciences project grant of $248,151 will support high resolution optical interferometry studies of interacting binary star systems to better understand stellar evolution and the formation of neutron stars and black holes. Led by Dr. [PI name] at New Mexico Institute of Mining and Technology, the team will use the Center for High Angular Resolution Astronomy array to collect interferometric data on known symbiotic binary stars over a...
- 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 from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) provides $423,155.00 to the University of Pittsburgh to conduct collaborative research on the final stages of evolution for the most massive stars. The project aims to constrain uncertainties in massive stellar evolution, such as mass loss efficiency and supernova kick impacts, by precisely measuring formation timescales and evolutionary pathways for key stellar populations...
- The National Science Foundation Division of Astronomical Sciences awarded a $462,848 Project Grant under the Mathematical and Physical Sciences (47.049) program to The SETI Institute. The grant will fund a comprehensive analysis of period changes in eclipsing binary stars from 2022-2025. Researchers will measure decades-long period changes in hundreds of eclipsing binaries to constrain the internal structure of individual stars and probe for additional bodies like planets or stars. They will use...
This federal Project Grant award, provided by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049), will support collaborative research to improve understanding of the common envelope evolution process in binary star systems. The investigators will use telescopes and computer simulations to study this poorly understood phenomenon, where a lower-mass star orbits within a larger, expanding star, resulting in dramatic energy exchange and mass ejection. The researchers will characterize a benchmark set of 52 detached post-common envelope binary systems located in stellar clusters, directly relating their pre- and post-common envelope conditions to provide critical constraints on stellar evolution and population synthesis models. The total award amount is $297,512.00, with a project period from August 1, 2025 to July 31, 2028. No sub-awards are planned under this grant.
