Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Wat is emotie in menselijke en niet-menselijke dieren? Hoe worden emoties uitgedrukt en hoe beïnvloeden ze onze interacties, onze beslissing om te vertrouwen, te wantrouwen en mee te werken? Waarom imiteren en synchroniseren we affectieve processen?

My work focuses on a class of astronomical objects called protoplanetary disks.

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

To study how planetary systems come into existence we study much younger systems still in formation.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

Stress komt veel voor in de huidige samenleving. Dit is zorgwekkend, aangezien onderzoek herhaaldelijk heeft aangetoond dat stress een negatieve invloed heeft op de lichamelijke gezondheid. Zo vergroot stress bijvoorbeeld de kans op hart- en vaatziekten.

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

The aim of this workshop is to open up the discussion of textual communities in Late Antiquity and the early Middle Ages, by offering a platform for PhD students from all over the world and from various disciplines to present their own research and discuss it with others. Deadline: April 23.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.
