The aim of this project is to study the coupled internal and orbital evolution of the Galilean satellites of Jupiter. The central concept coupling the orbit with the interior is tidal heating, the heat dissipated in a satellite and in Jupiter because of tidal deformation. Tidal heating in a satellite tends to circularize the orbit, which in turn reduces tidal dissipation, whereas tidal heating in the planet makes the orbits of satellites more elliptical and increases satellite tidal dissipation. Tidal heating can be an important energy source for satellites and can play a crucial role in the existence of subsurface oceans. In this project, we will develop a self-consistent model of the coupled evolution that also includes the evolution of Jupiter. This project will help to prepare the upcoming ESA JUICE mission to Jupiter and its Galilean satellites, in which ROB is heavily involved.
The goal of the project is to use observations of the Earth’s rotation and magnetic and gravity fields in synergy, and to link them with core flow models, in order to provide new information on the dynamical processes occurring in the fluid core and at the core-mantle boundary.
The contract for a doctor of science with at least 6 years of experience, will be until the end of the GRACEFUL project (August 2024). We are looking for an enthusiastic, motivated scientist and able to lead young researchers.
ROB hires a full-time scientific collaborator, who will play a central role in ROB’s research on campfires. The new collaborator will be involved in the detection and characterization of EUV brightenings and the study of their properties as derived from dedicated observation by instruments such as EUI, PHI, SPICE, and AIA, using techniques such as differential emission measure, coronal stereoscopy and spectroscopy. The research will include both case studies of EUV brightenings and statistical studies of their properties. The distribution of their energies is especially interesting as it extends our knowledgebase of the contribution of coronal brightenings to coronal heating. The new collaborator will aid in producing an open catalogue of EUV brightenings, which can be consulted/employed by the solar physics community.
The Centre Spatial de Liège of the University of Liege and the Royal Observatory of Belgium invite applications for a full-time post-doctoral position to fill their profile CHIPS – Conceiving Hardware to Investigate the Physics of the Sun, open in the framework of the Belgian federal FED-tWIN programme (Programme of sustainable research cooperation between the federal scientific institutes (FSI) and the universities). This position involves a part time (50 %) scientific position at the Royal Observatory of Belgium, and a complementary part time (50 %) post-doctoral position at the Centre Spatial de Liège of the University of Liège in the field of space instrumentation.
A contractual scientific position is available at the Royal Observatory of Belgium for a person to work on the detection of surface information on airless bodies with specific focus on the Martian moons Phobos and Deimos. Ongoing observations of the NOMAD spectrometer of the ESA TGO (Trace Gas orbiter) mission and future observations of ESA’s Hera mission with its optical instruments (including the Thermal infrared Imager) during the planned Mars flyby will be studied.
The Operational Directorate (OD) “Seismology-Gravimetry” of the Royal Observatory of Belgium (ROB) is looking for an experienced seismologist to strengthen its team on the topic of intraplate and induced seismicity, and to contribute to fulfilling its tasks and missions. The research themes of this OD consist of preserving, studying and developing seismological knowledge, oriented towards the study of earthquakes in Belgium and worldwide. The OD is also in charge of gravimetry, focusing on time-variable gravity.
