Optically determined physical properties 2. Ephemeris 3. Masterlog of Goldstone and Arecibo observations 4. Disc-integrated radar properties, delay-Doppler dispersions 5. Radar astrometry 6. Orbit 7. Future and past close encounters with planets & uncertainties 8. NEA elongations from radar observations 9. Physical properties of the shape model 10. List of crater candidates FIGURES ======= 1. Sky motion during the radar observations (plotted on a sphere) 2. Goldstone (and Arecibo...?) CW spectra 3. Delay-Doppler image collage as a function of date w/POS views of the shape model that include axes 4. Delay-Doppler image sequence from Aug 8 showing rotation 5. Rotation sequence of the shape model in stereo pairs w/lat & long 6. SC, OC, and SC/OC images color bar (3-sigma) 7. SC/OC and shape model with low SC/OC region on Aug 2 outlined with trace 8. Distribution of mass along the long axis 9. High-resolution radius vs. latitude and longitude contour map, grayscale or color scale 10. R-plot (cratering) 11. local surface slope mapped onto the shape model 12. Shape model with locations of features Other figure ideas (some for other papers) ------------------------------------------ 1. Shape model fit to lightcurves. Save for another paper. 2. Orientation and illumination of shape model during lightcurve extrema, vis-IR spectroscopy, and thermal radiometry. Save for another paper. 3. Profiles through some of the concavities. 4. Lat & Long projection with crater locations marked according to actual sizes. 5. R-porosity figure 6. Surface rocks figures 7. Albedo-diameter figure 8. Impact crater depth/diameter ratios. Can we do that? Other research ideas -------------------- 1. Simulations of orbits about JM8 2. collisions into JM8: try to explain the shape, large craters, constrain porosity 3. Video of JM8, Toutatis, and other shape models rotating (Castalia, Bacchus, Geographos, Eros, Earth) 4. Interactive website that allows user to pick illumination direction on the shape model. 5. Video of illumination of the POS view of the shape model as a function of time and the corresponding lightcurves. Use real constellations & planets in the background. 6. Video of POS view of the shape model vs time and corresponding vis-IR spectra 7. Sky seen from a point on JM8's surface as the asteroid rotates: use real constellations and positions of planets. 8. Do statistical tests to check for correlations between SC/OC vs rotation 9. Separate paper: cratering on 1999 JM8? The observations are analogous to a spacecraft encounter, which typically generate multiple papers. 10. Evolution of the orbital elements vs time over the interval in which the orbit can be computed reliably. Can also plot the estimated uncertainties both in absolute and in relative terms. 11. Investigate Yarkovsky forces acting on 1999 JM8 using the real spin vector and orbit. Then expand by stochastically resetting the spin vector to simulate impacts but retain the shape. 12. Is the geographic distribution of craters on JM8 random?
