Drifting discrete Jovian radio bursts reveal acceleration processes related to Ganymede and the main aurora

open access: yesNature Communications, 2023
Radio detection at high time-frequency resolutions is a powerful means of remotely studying electron acceleration processes. Radio bursts have characteristics (polarization, drift, periodicity) making them easier to detect than slowly variable emissions.

Are Abbreviated Mental Test (AMT) and Ascertain Dementia 8 Indonesia (AD8-INA) Questionnaires More Superior than Mini-Mental State Examination (MMSE) as Dementia Screening Instrument among Elderly in Rural Areas?

open access: yesAksona, 2022
Introduction: Dementia screening provides numerous benefits to its users. However, current screening methods have several limitations regarding applicability and accuracy, making it difficult to accommodate the results. Objective: To describe whether the

Field-aligned beams and reconnection in the jovian magnetotail [PDF]

open access: yesIcarus 217 (2012) 55-65, 2012
The release of plasma in the jovian magnetotail is observed in the form of plasmoids, travelling compression regions, field-aligned particle beams and flux-rope like events. We demonstrate that electrons propagate along the magnetic field lines in the plasma sheet boundary layer (PSBL), while close to the current sheet center the electron distribution ...

The Response of Broadband Kilometric Radiation to Compressions of the Jovian Magnetosphere

open access: yesThe Astrophysical Journal
In the planetary magnetosphere, plasma waves act as the medium for particles to transfer energy. Jupiter is the largest planet in our solar system, and the giant magnetosphere is full of energetic particles, producing intense radio emissions.

Modeling the Jovian subnebula: I - Thermodynamical conditions and migration of proto-satellites [PDF]

open access: yes, 2005
We have developed an evolutionary turbulent model of the Jovian subnebula consistent with the extended core accretion formation models of Jupiter described by Alibert et al. (2005b) and derived from Alibert et al. (2004,2005a). This model takes into account the vertical structure of the subnebula, as well as the evolution of the surface density as ...

Spatial Distribution of Ion Cyclotron Waves at Io

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Ion cyclotron waves at Io are important for understanding the complex interactions between Io and Jupiter's magnetosphere. In this study, we analyze the spatial distributions of ion cyclotron waves at Io using data from seven close flybys of Io—five by Galileo and two by Juno.

TOI-1670 c, a 40 day Orbital Period Warm Jupiter in a Compact System, Is Well Aligned

open access: yesThe Astrophysical Journal Letters, 2023
We report the measurement of the sky-projected obliquity angle λ of the warm Jovian exoplanet TOI-1670 c via the Rossiter–McLaughlin effect. We observed the transit window during UT 2023 April 20 for 7 continuous hours with NEID on the 3.5 m WIYN ...

Near-infrared Brightness of the Galilean Satellites Eclipsed in Jovian Shadow: A New Technique to Investigate Jovian Upper Atmosphere [PDF]

open access: yes, 2014
We have discovered that Europa, Ganymede and Callisto are bright around 1.5 {\mu}m even when not directly lit by sunlight, based on observations from the Hubble Space Telescope and the Subaru Telescope. The observations were conducted with non-sidereal tracking on Jupiter outside of the field of view to reduce the stray light subtraction uncertainty ...

Control of the Jovian Magnetopause by Iogenic Plasma: Initial Results From Global MHD Simulations

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The size and variability of Jupiter's magnetosphere are not only determined by upstream conditions but also substantially influenced by internal processes within Jupiter's magnetosphere, specifically the dynamics of the rotation magnetodisc.

Sub‐Auroral Heating at Jupiter Following a Solar Wind Compression

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Jupiter's polar aurorae deliver significant heating at the poles, thought to spread across the planet through atmospheric winds. Additionally, ground‐based Keck observations have revealed a large‐scale high‐temperature region, spatially distinct from the aurorae.
