SuperCam Raman Activities at Jezero Crater, Mars: Observational Strategies, Data Processing, and Mineral Detections During the First 1000 Sols

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mars 2020 Perseverance rover introduced Raman spectroscopy to in situ planetary exploration for the first time when it landed in Jezero crater on Mars in February 2021. The SuperCam instrument onboard Perseverance is a multi‐analytical tool capable of acquiring time‐resolved Raman data from Martian targets at standoff distances of a few ...

Evidence for Non‐Monotonic and Broadband Electron Distributions in the Europa Footprint Tail Revealed by Juno In Situ Measurements

Geophysical Research Letters, 2023
We characterize the precipitating electrons accelerated in the Europa‐magnetosphere interaction by analyzing in situ measurements and remote sensing observations recorded during 10 crossings of the flux tubes connected to Europa's auroral footprint tail ...

Scalable N-body code for the modelling of early-type galaxies

, 2007
Early-type galaxies exhibit a wealth of photometric and dynamical structures. These signatures are fossil records of their formation and evolution processes.

APXS Derived Geochemistry of Shallow Water Lens Bodies Within the Mirador Formation, Gale Crater, Mars—Evidence for Intermittent Wet Periods and Implications for the Water Record

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mount Sharp group in Gale crater is typically interpreted to record a progressive change (with increasing elevation) from wetter fluvio‐lacustrine environments to dry, eolian environments. This shift has been linked to orbital evidence for a global change in environmental and depositional conditions leading to an overall drying out of Mars.

Investigating magnetic activity of F stars with the it Kepler mission

, 2013
The dynamo process is believed to drive the magnetic activity of stars like the Sun that have an outer convection zone. Large spectroscopic surveys showed that there is a relation between the rotation periods and the cycle periods: the longer the ...

Ion Composition and Electron Pitch Angle Variations for Interchange Events in Jupiter's Inner Magnetosphere

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The outward transport of plasma and magnetic fluxes in the gas giant magnetospheres is balanced with a return flow of flux tubes emptied through magnetic reconnection. Evidence of interchange motions between inward and outward moving flux tubes have long been reported around Jupiter and Saturn.
