Mercury-T: A new code to study tidally evolving multi-planet systems. Applications to Kepler-62 [PDF]
, 2015 A large proportion of observed planetary systems contain several planets in a compact orbital configuration, and often harbor at least one close-in object. These systems are then most likely tidally evolving.

Explaining mercury via a single giant impact is highly unlikely [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The classical scenario of terrestrial planet formation is characterized by a phase of giant impacts among Moon-to-Mars mass planetary embryos. While the classic model and its adaptations have produced adequate analogs of the outer three terrestrial ...

The Origin and Differentiation of Planet Mercury
Elements, 2019 the formation of the (proto-)planet. We present some possible causes of metal/ silicate fractionation, including element fractionation in the solar nebula (condensation sequence, dynamical mechanism), impact erosion, and high-temperature evaporation of ...

MESSENGER Observations of Reconnection in Mercury's Magnetotail Under Strong IMF Forcing
Journal of Geophysical Research: Space Physics, 2023 The MESSENGER spacecraft typically crossed Mercury's magnetotail current sheet relatively close to the planet, that is, less than 2.5 RM (planet radius; 2,440 km). Magnetometer measurements are used to detect active reconnection events by identifying the

The GENGA Code: Gravitational Encounters in N-body simulations with GPU Acceleration [PDF]
, 2014 We describe an open source GPU implementation of a hybrid symplectic N-body integrator, GENGA (Gravitational ENcounters with Gpu Acceleration), designed to integrate planet and planetesimal dynamics in the late stage of planet formation and stability ...

Widespread effusive volcanism on Mercury likely ended by about 3.5 Ga
Geophysical Research Letters, 2016 Crater size–frequency analyses have shown that the largest volcanic plains deposits on Mercury were emplaced around 3.7 Ga, as determined with recent model production function chronologies for impact crater formation on that planet.

RELIEF OF MERCURY AND THE MOON: FROM MORPHOMETRY TO MORPHOLOGICAL MAPPING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 The MESSENGER mission (2011–2015) gives us an opportunity to gain new knowledge about Mercury which is still the least explored planet of the terrestrial group.

Geomorphological processes on terrestrial planetary surfaces [PDF]
, 1980 This review deals with features and processes on planetary surfaces, first by examining the impact of photographic explorations of Moon, Mars, and Mercury on studies of surface processes on our own planet, and second by treating matters related to ...

Observational evidence of ring current in the magnetosphere of Mercury
Nature Communications, 2022 The magnetic gradient and curvature drift of energetic ions can form a longitudinal electric current around a planet known as the ring current, that has been observed in the intrinsic magnetospheres of Earth, Jupiter, and Saturn.
