Astrometric positions for 18 irregular satellites of giant planets from 23 years of observations

, 2015
The irregular satellites of the giant planets are believed to have been captured during the evolution of the solar system. Knowing their physical parameters, such as size, density, and albedo is important for constraining where they came from and how ...

Deconstructing Menvertising Stereotypes: A Systematic Review, Research Agenda and Practical Implications

Journal of Consumer Behaviour, Volume 25, Issue 1, Page 57-84, January 2026.
ABSTRACT Since the #MeToo movement of 2017, consumers have been looking for more diversity and inclusion in their world. As a result, advertisers are implementing strategies such as femvertising and even menvertising to win over this more inclusion‐oriented audience. A large number of studies have focused on women, particularly representations of women

From international land deals to local informal agreements: regulations of and local reactions to agricultural investments in Madagascar [PDF]

, 2011
In 2009, the 1.3 million hectare agricultural project planned in Madagascar by Daewoo Logistics exemplified the paradoxical position of the Malagasy state; simultaneously encouraging the development of large-scale acquisition and implementing a land ...

(SC)RMI: A (S)emi-(C)lassical (R)elativistic (M)otion (I)integrator, to model the orbits of space probes around the Earth and other planets

, 2006
Today, the motion of spacecrafts is still described according to the classical Newtonian equations plus the so-called "relativistic corrections", computed with the required precision using the Post-(Post-)Newtonian formalism.

On-sky observations with an achromatic hybrid phase knife coronagraph in the visible [PDF]

, 2006
CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context of the direct detection of extra-solar planets.

Ferromagnesian Clay Diversity Across Mars' Crustal Dichotomy: A Window Into Early Aqueous Environments

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Extensive research over the past two decades has shown that early Mars likely had a warmer, wetter climate with widespread water activity. Ferromagnesian (Fe,Mg‐rich) clay deposits are compelling markers of these ancient environments, helping reconstruct Mars' hydrologic evolution, assess past habitability, and guide future exploration.

Asymmetries in stellar streams induced by a galactic merger

Astronomy & Astrophysics
Stellar streams are sensitive to perturbations from, for example, giant molecular clouds, bars and spiral arms, infalling dwarf galaxies, or globular clusters which can imprint gaps, clumps, spurs, and asymmetries in tails.

A high-resolution gravimetric quasigeoid model for Vietnam

Earth, Planets and Space, 2019
A high-resolution gravimetric quasigeoid model for Vietnam and its surrounding areas was determined based on new gravity data. A set of 29,121 land gravity measurements was used in combination with fill-in data where no gravity data existed.
