- This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research effort between the Space Science Institute, the University of Alabama in Huntsville, and Ben-Gurion University in Israel. The primary goal is to advance fundamental understanding of shock waves in astrophysical plasmas, which can efficiently convert flow energy into heat and particle acceleration. The $226,897 award, spanning August 1,...
- This $105,935 federal Project Grant award was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the Seti Institute in Mountain View, CA. The funding will support collaborative research to carry out theoretical analysis and computer simulations of solar observations. The goal is to test the hypothesis that heating in the Sun's atmosphere is caused by small-scale plasma processes referred to as the thermal Farley-Buneman instability, which may also occur in other...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $589,888 to the Space Science Institute (SSI) to conduct a series of laboratory experiments to better understand wave-wave interaction processes that may control imbalanced solar wind turbulence at ion scales. Specifically, the project will investigate the behavior of two interactions between co-propagating Alfvén waves: a novel interaction driven by Hall physics, and the dispersive...
- This National Science Foundation Project Grant of $508,504 provides funding from November 1, 2022 to October 31, 2025 under the Geosciences program (CFDA 47.050) to advance understanding of coronal mass ejections (CMEs) from the Sun. Led by underrepresented groups in STEM, the award supports physics-based and statistical studies to quantify the structure and evolution of magnetic flux ropes from the solar photosphere to the inner heliosphere. Researchers will characterize CME flux ropes using...
- This $297,162 Project Grant award from the National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) under CFDA 43.001 (Science) will fund research by the University of Maryland, College Park to investigate the roles of turbulence and reconnection in generating suprathermal seed populations for solar energetic particle (SEP) events. The project aims to expand understanding of the physical processes underlying SEP events, which are critical for space weather...
- This $300,519 National Science Foundation project grant supports research and outreach activities to study the parametric decay instability mechanism's potential role in solar corona heating. Funded under the Geosciences program, which supports basic research to improve understanding of Earth's integrated systems, the two-year award to New Mexico Consortium will analyze observational data and conduct numerical simulations. Postdoctoral researchers and undergraduate students at Columbia...
SHINE: SOLAR ENERGETIC PARTICLES MEDIATING INTERPLANETARY SHOCKS CLOSE TO THE SUN -SOLAR ENERGETIC PARTICLES (SEPS) ARE HIGH-ENERGY PARTICLES THAT CAN PROPAGATE FROM THE SUN ALL THE WAY TO THE SURFACE OF THE EARTH, WHICH CAN CAUSE SIGNIFICANT DISRUPTIONS TO COMMUNICATION SYSTEMS. THEIR GENERATION MECHANISMS REMAIN A SUBJECT OF MUCH DEBATE, WITH STRONG CORONAL AND INTERPLANETARY DISCONTINUITIES OR SHOCKS DRIVEN BY CORONAL MASS EJECTIONS (CME) BEING LIKELY RESPONSIBLE. PREVIOUS OBSERVATIONS STUDIED THESE SHOCKS AT DIFFERENT SOLAR DISTANCES FROM THE EARTH?S ORBIT TO THE OUTER HELIOSPHERE, BUT WERE LIMITED TO DISTANCES MOSTLY OUTSIDE THE EARTH?S ORBIT (>1 AU). CURRENTLY, HOWEVER, OBSERVATIONS WITH PARKER SOLAR PROBE (PSP) AND SOLAR ORBITER (SOLO) ALLOW US TO BUILD A MORE COMPLETE PICTURE BY PROBING EXTENSIVELY DISTANCES BELOW 1 AU. A KEY CONSEQUENCE OF STUDYING THIS REGION, WHICH IS THE GOAL OF THIS PROJECT, IS THAT THESE IN-SITU OBSERVATIONS WILL PROVIDE SEP AND SHOCK MEASUREMENTS THAT ARE DRAMATICALLY LESS AFFECTED BY TRANSPORT EFFECTS AS THE SPACECRAFT PROGRESSIVELY GET CLOSER TO THE SUN. THE DATA FROM PSP AND SOLO WILL BE ANALYZED FOR PERIODS WHEN THESE SPACECRAFT OBSERVE SHOCK EVENTS WITH EXCEPTIONALLY HIGH SEP INTENSITIES. THE RESULTS WILL ADDRESS THE SIGNIFICANT ISSUE OF ENERGETIC PARTICLE ACCELERATION BY SHOCKS NEAR THE SUN AND HOW THE PARTICLES AFFECT THE STRUCTURE OF THESE YOUNG SHOCKS. ADDITIONALLY, AS ENERGETIC-PARTICLE-MEDIATED SHOCKS ARE PREDICTED TO OCCUR IN VARIOUS ASTROPHYSICAL SETTINGS ACROSS A BROAD RANGE OF SPATIAL AND TEMPORAL SCALES, OUR COMPREHENSIVE SEARCH FOR SUCH STRUCTURES VERY CLOSE TO OUR SUN MAY FUNDAMENTALLY CONTRIBUTE TO OUR UNDERSTANDING OF WELL-KNOWN ?COSMIC RAY?-MEDIATED COLLISIONLESS SHOCKS. THE SCIENCE GOALS OF THIS PROJECT ARE TO (1) QUANTIFY SEP-MEDIATED SHOCKS, (2) ASSESS SEP IMPACT ON SHOCK MEDIATION, AND (3) EXPLORE SHOCK-SEP RELATIONSHIPS. THIS PROJECT WILL SUPPORT AN EARLY-CAREER FEMALE SCIENTIST AND AN UNDERGRADUATE STUDENT FROM THE APL CIRCUIT PROGRAM TO WORK ON THIS PROJECT WHICH WILL BE PROMOTING RESEARCH AND EDUCATION. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
