The Increasingly Strange Polarimetric Behavior of the Barbarian Asteroids
The Planetary Science Journal, 2023 Polarization phase-curve measurements provide a unique constraint on the surface properties of asteroids that are complementary to those from photometry and spectroscopy and have led to the identification of the “Barbarian” asteroids as a class of ...

P/2017 S5: Another Active Asteroid Associated with the Theobalda Family [PDF]
Research Notes of the American Astronomical Society, Volume 2,
Issue 3, id. 129, 2018, 2018 In this note we have shown that a newly discovered comet P/2017 S5 (ATLAS), that moves around the Sun in an asteroid-like orbit, is a member of the Theobalda asteroid family.

Journal of the Royal Anthropological Institute, EarlyView.Space activities in subarctic Sweden are predicated on older infrastructures of underground resource extraction. The ongoing expansion of the country's rocket launch site outside Kiruna relies on the Swedish state's historical construction of the region as a resource frontier.

Dynamic 3D Simulation of Surface Charging on Rotating Asteroids
The Astrophysical JournalThe surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood.

Asteroid taxonomic signatures from photometric phase curves [PDF]
, 2012 We explore the correlation between an asteroid's taxonomy and photometric phase curve using the H, G12 photometric phase function, with the shape of the phase function described by the single parameter G12. We explore the usability of G12 in taxonomic classification for individual objects, asteroid families, and dynamical groups.

Finding the aten asteroids posing potential danger for Earth
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 We made the research of orbit evolutions of 321 aten asteroids on the 400 years time interval (1800–2200). We found five asteroids which come close to the Earth at a distance less than 150000 km.

Ion Beam Shepherd for Asteroid Deflection [PDF]
arXiv, 2011 We present a novel concept to impart a continuous thrust to an Earth threatening asteroid from a hovering spacecraft without need for physical attachment nor gravitational interaction with the asteroid. The concept involves an ion thruster placed at a distance of a few asteroid diameters directing a stream of quasi-neutral plasma against the asteroid ...
