Untrackable distal ejecta on planetary surfaces by Rui Xu, Zhiyong Xiao, Fanglu Luo, Yichen Wang, Jun Cui

“…Heterogeneous shock impedances of planetary materials cause abrupt changes of ejection angles, forming non-radial ejecta. Interpretations for provenances of surface deposits and ages derived from crater counts are affected by such untrackable ejecta.…”

Evolutionary signatures in complex ejecta and their driven shocks by C. J. Farrugia, D. B. Berdichevsky

“…We examine interplanetary signatures of ejecta-ejecta interactions. To this end, two time intervals of inner-heliospheric (≤1AU) observations separated by 2 solar cycles are chosen where ejecta/magnetic clouds are in the process of interacting to form complex ejecta. …”

Dust Formation in the Ejecta of Common Envelope Systems by Lu, G, Zhu, C, Podsiadlowski, P

“…The actual dust masses produced in the CE ejecta depend strongly on their temperature and density evolution. …”

Multipoint Observations of the Dynamics at an ICME Sheath–Ejecta Boundary by Matti Ala-Lahti, Tuija I. Pulkkinen, Julia Ruohotie, Mojtaba Akhavan-Tafti, Simon W. Good, Emilia K. J. Kilpua

“…Here, an ICME front boundary, which separates the confined ejecta from the mixed, interacted sheath–ejecta plasma upstream, is analyzed in a multipoint study examining the ICME at 1 au on 2020 April 20. …”

Long-term Evolution in Ionization of Ejecta Illuminated by Eta Carinae by Augusto Damineli, Noel D. Richardson, Felipe Navarete, Theodore. R. Gull, Eduardo Fernández-Lajús, Anthony F. J. Moffat, Desmond J. Hillier, Gerd Weigelt, Michael F. Corcoran

“…Others suggest evolution in the occulting ejecta. The brightness jump in the 1940s, which coincided with the appearance of narrow forbidden emission lines, may have been caused by the clearing and ionization of intervening circumstellar ejecta. …”
