Applicant Login Postdoctoral Research Assistant III, S1 Apply now Job no: 501974 Department: Center for Space Plasma & Aeronomic Research Work type: Postdoctoral Student Employee Location: Alabama Categories: Research - Other Purpose of the Position: The Postdoctoral Research Assistant III will carry out NASA sponsored research on the interaction of energetic charged particles with small scale magnetic flux ropes in the large-scale solar wind. The research methodology includes both numerical and observational analysis.Duties/ResponsibilitiesPerform research and numerical simulations of energetic charged particle acceleration by a collection of dynamic small-scale flux ropes (SMFRs) in the large-scale solar wind and by nearby heliospheric shocks. • Develop a kinetic-focused transport equation for energetic particle interaction with numerous SMFRs and a traveling shock will be solved numerically using existing numerical codes employing finite difference and finite volume, or stochastic differential equation methods. • Utilize numerical model to study: (1) The radial evolution of energetic particle acceleration by SMFRs in the inner heliosphere between the Sun and Earth, (2) the ability of energetic particle stage 1 acceleration by SMFRs in the vicinity of inner heliospheric shocks to form a seed population of suprathermal particles for injection into stage 2 diffusive shock acceleration (DSA) at these shocks and, (3) the impact of the injection process on the accelerated particle spectrum generated by stage 2 DSA and the associated levels of energetic particle fluxes at nearby heliospheric shocks. • Identify enhanced energetic particle flux events in inner heliospheric spacecraft data generated by dynamic SMFR acceleration in the vicinity of inner heliospheric shocks. • Use numerical modeling to reproduce the observations, validate the kinetic transport theory, identify the most important SMFR acceleration mechanisms, and better understand the importance of SMFR-accelerated particle populations for injection into DSA at inner heliospheric shocks. • Assist the supervisor in research activities involving graduate students; Specific duties include guiding in developing and -or using analysis tools and computing codes for relevant research needs. Minimum Requirements: • Ph.D. in Space Science, Physics, or Astronomy or Astrophysics; • 2 - 2 1/2 years of full-time verifiable research work experience in heliophysics or astrophysics• Proficiency in related computer software Desired Qualifications: • Experience with remote-sensing solar observations is desired Published Salary (if available): $52,216 - $55,000 Advertised: Jan 23 2025 Central Standard Time Applications close: Back to search results Apply now Refer a friend Whatsapp Facebook LinkedIn Email App Send me jobs like these We will email you new jobs that match this search.
