    • Analysis of full microwave propagation and backpropagation for a complex asteroid analogue via single-point quasi-monostatic data 

      Sorsa, Liisa-Ida; Pursiainen, Sampsa; Eyraud, Christelle (2021)
      article
      Information carried by the full wave field is particularly important in applications involving wave propagation, backpropa- gation, and a sparse distribution of measurement points, such as in tomographic imaging of a small ...
    • Asteroid (16) Psyche's primordial shape : A possible Jacobi ellipsoid 

      Ferrais, M.; Vernazza, P.; Jorda, L.; Rambaux, N.; Hanuš, J.; Carry, B.; Marchis, F.; Marsset, M.; Viikinkoski, M.; Brož, M.; Fetick, R.; Drouard, A.; Fusco, T.; Birlan, M.; Podlewska-Gaca, E.; Jehin, E.; Bartczak, P.; Berthier, J.; Castillo-Rogez, J.; Cipriani, F.; Colas, F.; Dudziński, G.; Dumas, C.; Ğ Urech, J.; Kaasalainen, M.; Kryszczynska, A.; Lamy, P.; Le Coroller, H.; Marciniak, A.; Michalowski, T.; Michel, P.; Santana-Ros, T.; Tanga, P.; Vachier, F.; Vigan, A.; Witasse, O.; Yang, B. (29.06.2020)
      article
      Context. Asteroid (16) Psyche is the largest M-type asteroid in the main belt and the target of the NASA Psyche mission. It is also the only asteroid of this size (D> 200 km) known to be metal rich. Although various ...
    • Evidence for differentiation of the most primitive small bodies 

      Carry, B.; Vernazza, P.; Vachier, F.; Neveu, M.; Berthier, J.; Hanuš, J.; Ferrais, M.; Jorda, L.; Marsset, M.; Viikinkoski, M.; Bartczak, P.; Behrend, R.; Benkhaldoun, Z.; Birlan, M.; Castillo-Rogez, J.; Cipriani, F.; Colas, F.; Drouard, A.; Dudziński, G. P.; Desmars, J.; Dumas, C.; Ďurech, J.; Fetick, R.; Fusco, T.; Grice, J.; Jehin, E.; Kaasalainen, M.; Kryszczynska, A.; Lamy, P.; Marchis, F.; Marciniak, A.; Michalowski, T.; Michel, P.; Pajuelo, M.; Podlewska-Gaca, E.; Rambaux, N.; Santana-Ros, T.; Storrs, A.; Tanga, P.; Vigan, A.; Warner, B.; Wieczorek, M.; Witasse, O.; Yang, B. (17.06.2021)
      article
      Context. Dynamical models of Solar System evolution have suggested that the so-called P- and D-type volatile-rich asteroids formed in the outer Solar System beyond Neptune's orbit and may be genetically related to the ...
    • Imaging of the internal structure of an asteroid analogue from quasi-monostatic microwave measurement data : I. The frequency domain approach 

      Dufaure, A.; Eyraud, C.; Sorsa, L. I.; Yusuf, Y. O.; Pursiainen, S.; Geffrin, J. M. (06 / 2023)
      article
      Context. The internal structure of small Solar System bodies (SSSBs) is still poorly understood, although it can provide important information about the formation process of asteroids and comets. Space radars can provide ...
    • Imaging of the internal structure of an asteroid analogue from quasi-monostatic microwave measurement data : II. The time domain approach 

      Sorsa, Liisa Ida; Yusuf, Yusuf Oluwatoki; Dufaure, Astrid; Geffrin, Jean Michel; Eyraud, Christelle; Pursiainen, Sampsa (06 / 2023)
      article
      Context. The internal structures of small solar system bodies (SSSBs) are still poorly understood. In this paper, we find an experimental tomographic reconstruction of coarse high-contrast details inside a complex-structured ...
    • VLT/SPHERE imaging survey of the largest main-belt asteroids : Final results and synthesis 

      Vernazza, P.; Ferrais, M.; Jorda, L.; Hanuš, J.; Carry, B.; Marsset, M.; Brož, M.; Fetick, R.; Viikinkoski, M.; Marchis, F.; Vachier, F.; Drouard, A.; Fusco, T.; Birlan, M.; Podlewska-Gaca, E.; Rambaux, N.; Neveu, M.; Bartczak, P.; Dudziński, G.; Jehin, E.; Beck, P.; Berthier, J.; Castillo-Rogez, J.; Cipriani, F.; Colas, F.; Dumas, C.; ǦUrech, J.; Grice, J.; Kaasalainen, M.; Kryszczynska, A.; Lamy, P.; Le Coroller, H.; Marciniak, A.; Michalowski, T.; Michel, P.; Santana-Ros, T.; Tanga, P.; Vigan, A.; Witasse, O.; Yang, B.; Antonini, P.; Audejean, M.; Aurard, P.; Behrend, R.; Benkhaldoun, Z.; Bosch, J. M.; Chapman, A.; Dalmon, L.; Fauvaud, S.; Hamanowa, Hiroko; Hamanowa, Hiromi; His, J.; Jones, A.; Kim, D. H.; Kim, M. J.; Krajewski, J.; Labrevoir, O.; Leroy, A.; Livet, F.; Molina, D.; Montaigut, R.; Oey, J.; Payre, N.; Reddy, V.; Sabin, P.; Sanchez, A. G.; Socha, L. (12.10.2021)
      article
      Until recently, the 3D shape, and therefore density (when combining the volume estimate with available mass estimates), and surface topography of the vast majority of the largest (D ≥ 100 km) main-belt asteroids have ...
