Protostellar jets and planet-forming disks: Witnessing the formation of Solar System analogues with interferometry
The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.
-
Exo-planets, star and planet formation
Wetenschappers bij de Leidse Sterrewacht onderzoeken de oorsprong van sterren en hun planetenstelsels. Ze detecteren en karakteriseren planeten rondom andere sterren (exoplaneten). Ze onderzoeken hoe sterren en planeten ontstaan. En ze volgen moleculen van interstellaire wolken tot planetenstelsels…

Ingredients of the planet-formation puzzle
High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.
-
Galaxy formation traced by heavy element pollution
Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.
-
A radio view of dust-obscured star formation
Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.
-
Turtles all the way down: multiscale simulations connecting star and planet formation
The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.
-
Uncovering the ingredients for planet formation
This thesis discusses the physical and chemical processes than influence the composition of forming planets.
-
Identifying the origins of galaxy formation
This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.
-
Metabolomic characterization of plant exudates and their correlation with plant defense systems
Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.
-
Distant star formation in the faint radio sky
One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.
-
Chemistry in embedded disks: setting the stage for planet formation
To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Impact of plant hormones on growth and development of actinobacteria
Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Dynamics of the Oort Cloud and Formation of Interstellar Comets Santiago Torres Rodriguez
The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

Bridging the gap between physics and chemistry in early stages of star formation
A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Above- and belowground interactions in Jacobaea vulgaris: zooming in and zooming out from a plant-soil feedback perspective
In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…
