358P/PANSTARRS Archives

(a) Modeled image from a Monte Carlo dust model for µm-size grains accelerated by outgassing water from 358P, using an active South pole, ε = 80◦ , and Φ = 245◦ , covering the inner 1500×1500 km of the coma as seen from JWST. Intensities in the model image indicate column density, where representative contours are shown as cyan lines. NIRCam F200W contours from Figure 6 are shown in white for comparison. (b) The same as (a), but for Φ = 260◦ as found by Moreno et al. (2013). -- astro-ph.EP
