A search for transit timing variation
, 2010 Photometric follow-ups of transiting exoplanets (TEPs) may lead to discoveries of additional, less massive bodies in extrasolar systems. This is possible by detecting and then analysing variations in transit timing of transiting exoplanets.

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.

Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.

JWST Discovers the Vertical Structure of Uranus' Ionosphere
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract On 19 January 2025, the James Webb Space Telescope (JWST) program # $\mathrm{\#}$5073 observed Uranus for almost a full rotation with NIRSpec. We present the first ever vertical ionospheric profiles of H3+ ${\mathrm{H}}_{3}^{+}$ temperature, volumetric density and total emission.

Biosignatures Search in Habitable Planets
Galaxies, 2019 The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of planets, from hot giants to rocky planets orbiting small

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

High Pressure Formation of the Eight‐Fold Coordinated Post‐Post Spinel MgFe2O4
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract MgFe2O4 was probed to 74(1) GPa and 2,840(130) K as a low‐pressure analog to post‐post spinel Mg2SiO4 predicted in super‐Earths using synchrotron multigrain X‐ray diffraction techniques in the laser‐heated diamond anvil cell. With high‐temperatures above 65 GPa the eight‐fold coordinated δ‐MgFe2O4 (Th3P4‐type) is stable with Mg and Fe ...
