What Can You Do As An Undergraduate Researcher?

  1. 1. What Can You Do As An Undergraduate Researcher?<br />Caleb Wherry<br />
  2. 2. What’s In Store….<br />NASA Jet Propulsion Laboratory, California Institute of Technology<br />PROMOS (PROper MOtion Software)<br />NASA Langley Research Center<br />Trajectory and Microphysical Modeling<br />Department of Energy Lawrence Livermore National Laboratory<br />Network Security at A National Laboratory<br />MIT QuISU Program<br />UGA Mathematical Biology & Numerical Analysis Workshop<br />Current Research<br />REUs<br />
  3. 3. PRO-MOTIONS<br />PROper MOTION Software<br />Caleb Wherry<br />Austin Peay State University, TN<br />NASA's Undergraduate Student Research Program<br />California Institute of Technology<br />Jet Propulsion Laboratory<br />Mentor: Dr. Raghvendra Sahai<br />
  4. 4. Overview<br />What is Proper Motion?<br />Proper Motion & Protoplanetary Nebulae<br />Image Registration (Preliminaries)<br />Central Star Location<br />Calculating Proper Motion<br />Selecting Fiducial Features In Nebula<br />Radially Symmetric Expansion<br />Applications of Proper Motion Measurements<br />Age of Nebula<br />3D Movement of Nebula<br />
  5. 5. What is Proper Motion?<br />Proper motion<br />Proper motion is the movement of a celestial body across the sky (parallel to our line of sight).<br />Anyone See A Concern With This????<br />
  6. 6. Objects of Study<br />Protoplanetary Nebulae (preplanetary)<br />Live between the AGB and Planetary Nebula (PN) Phases of A Star’s Stellar Evolution.<br />Life Span Is ~10,000 years (Extremely Short).<br />Starting Temperature: ~5,000 K.<br />Ending Temperature: ~30,000 K.<br />Size:1- 8 MΘ<br />
  7. 7.
  8. 8. Egg Nebula<br />Cat’s Eye Nebula<br />Eye Nebula<br />Red Rectangle<br />
  9. 9. Hubble & Spitzer Telescopes<br />What Are They?<br />Why Do We Use Them?<br />How Do We Use Them For Our Benefit?<br />What Problems Arise From Using Them?<br />Hint: Think About How We Might Actually Measure Proper Motion… Ideas? Why Would Using Hubble Make This Difficult To Do With High Precision…?<br />
  10. 10. Image Registration<br />Bicubic Spline Interpolation<br />
  11. 11. Central Star Location<br />
  12. 12. Calculation of Proper Motion<br />
  13. 13. Theory of Calculations<br />How Do Measurements of Single Proper Motions Yield the Proper Motion of the Nebula as a Whole?<br />Average Motion Experienced by Symmetric Pairs.<br />Average Motion Experienced by ALL Symmetric Pairs Combined.<br />Proper Motion of the Nebula Has to Subtracted Out of Individual Proper Motions in Order to Get the Actual Proper Motion of the Feature.<br />
  14. 14. Why Do These Measurements?<br />Calculate the Age of the Nebula and the Features in it.<br />3D Expansion of the Nebula (+ Dopler Shift)<br />
  15. 15. Software Side<br />IDL (Interactive Data Language)<br />GUI Development<br />Encapsulation of Multiple Code Bases<br />All-In-One Software Suit<br />Code Modularity and Agile-ness<br />Well Documented<br />Name: PROMOS (PROper Motion Software)<br />
  16. 16. PROMOS GUI<br />
