Long-term radial-velocity variations of the Sun as a star: The HARPS view [PDF]

, 2016
Stellar radial velocities play a fundamental role in the discovery of extrasolar planets and the measurement of their physical parameters as well as in the study of stellar physical properties.

Measuring Ganymede’s Librations with Laser Altimetry

Geosciences, 2019
Jupiter’s moon Ganymede might be in possession of a subsurface ocean located between two ice layers. However, from Galileo data it is not possible to unambiguously infer the thickness and densities of the individual layers.

Thermal Convection in the Core of Ganymede Inferred from Liquid Eutectic Fe-FeS Electrical Resistivity at High Pressures

Crystals, 2021
The core of Ganymede is suggested to be mainly Fe but with a significant proportion of S. Effects of S as a core constituent are freezing-point depression, allowing for a molten core at relatively low core temperatures, and modification of transport ...

Powering Ganymede's dynamo [PDF]

Journal of Geophysical Research: Planets, 2012
It is generally believed that Ganymede's core is composed of an Fe‐FeS alloy and that convective motions inside it are responsible for generating the satellite's magnetic field. Analysis of the melting behavior of Fe‐FeS alloys at Ganymede's core pressures suggests that, besides the growth of a solid inner core, convection can be driven by two novel ...

Modeling magnetospheric fields in the Jupiter system

, 2017
The various processes which generate magnetic fields within the Jupiter system are exemplary for a large class of similar processes occurring at other planets in the solar system, but also around extrasolar planets.

Jupiter as an exoplanet: UV to NIR transmission spectrum reveals hazes, a Na layer and possibly stratospheric H2O-ice clouds [PDF]

, 2015
Currently, the analysis of transmission spectra is the most successful technique to probe the chemical composition of exoplanet atmospheres. But the accuracy of these measurements is constrained by observational limitations and the diversity of possible ...

Evidence for Magnetic Reconnection at Ganymede's Upstream Magnetopause During the PJ34 Juno Flyby

Geophysical Research Letters, 2022
Juno made a close flyby of Ganymede and flew through its magnetosphere on 7 June 2021, including an outbound crossing of Ganymede's upstream magnetopause. We present plasma and magnetic field observations near the upstream magnetopause from Juno's Jovian

The Lense-Thirring effect in the Jovian system of the Galilean satellites and its measurability [PDF]

, 2005
In this paper we investigate the possibility of measuring the post-Newtonian general relativistic gravitomagnetic Lense-Thirring effect in the Jovian system of its Galilean satellites Io, Europa, Ganymede and Callisto in view of recent developments in ...

Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

Surface Features of Ganymede Revealed in Jupiter‐Shine by Juno’s Stellar Reference Unit

Geophysical Research Letters, 2022
On 7 June 2021, Juno crossed the orbital path of Jupiter’s moon Ganymede, flying within 1,046 km of the surface. Juno’s low‐light‐sensitive Stellar Reference Unit (SRU) navigation camera captured an image of the satellite’s dark side in a region of ...
