Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract During the late stages of planetary accretion, large differentiated impactors interacted with the Earth's magma ocean, producing clouds of iron droplets that sank and mixed with silicates. Using a novel fluid‐dynamic approach combining the Thermal and Rothman‐Keller multiphase Lattice Boltzmann Methods, we modeled the segregation of impactor ...

Jupiter’s Interior with an Inverted Helium Gradient
The Planetary Science JournalJupiter’s gravity field observed by NASA’s Juno spacecraft indicates that the density in the 10–100 GPa region is lower than one would expect from a H/He adiabat with 0.5–5× solar water abundance, as has been observationally inferred in Jupiter’s ...

Wide angle search for extrasolar planets by the transit method [PDF]
, 2008 The transit method is considered to be one of the most promising for discovering extrasolar planets. However, the method requires photometric precision of better than ∼ 1%.

The Linear Mixing Approximation in Silica–Water Mixtures at Planetary Conditions
The Astrophysical JournalThe linear mixing approximation (LMA) is often used in planetary models for calculating the equations of state (EOS) of mixtures. A commonly assumed planetary composition is a mixture of rock and water. Here we assess the accuracy of the LMA for pressure–

Isotopic ratios D/H and ¹⁵ N/¹⁴N in giant planets
, 2018 The determination of isotopic ratios in planets is important since it allows us to investigate the origins and initial composition of materials. The present work aims to determine the possible range of values for isotopic ratios D/H and ¹⁵N/¹⁴N in giant ...

The capture of Trojan asteroids by the giant planets during planetary migration [PDF]
, 2010 Of the four giant planets in the Solar system, only Jupiter and Neptune are currently known to possess swarms of Trojan asteroids – small objects that experience a 1:1 mean motion resonance with their host planet.

Flyby-induced Second Accretion as a Pathway to Giant Planets Around M Dwarfs
The Astrophysical Journal LettersClassical pebble and core accretion theories face a severe challenge: they struggle to produce giant planets around low-mass M dwarfs, whose protoplanetary disks contain insufficient material. Yet, discoveries of such systems continue to mount.

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]
, 2014 We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable
