Young suns and infant planets: Probing the origins of solar systems
Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

Anna wants to weigh solar systems
All the planets in our solar system orbit around the Sun in an ecliptical plane. This is to be expected because our solar system was formed from a so-called protoplanetary disc. PhD candidate Anna Miotello has studied these kinds of discs and how they influence the formation of stars and planets. PhD…

What tiny isotopes reveal about planets outside our solar system
Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

All comets in our solar system might come from the same place
All comets might share their place of birth, new research says. For the first time ever, astronomer Christian Eistrup applied chemical models to fourteen well-known comets, surprisingly finding a clear pattern. His publication has been accepted in the journal Astronomy & Astrophysics.

Astronomers find missing link for origin of water in solar systems
An international team of astronomers, including astronomers from Leiden University, has found the missing link in the path taken by water through star-forming clouds and young stars to comets and planets. They did so with the help of the ALMA observatory in Chile. The researchers published their findings…

Exploring strange new worlds with high-dispersion spectroscopy
Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Interstellar Catalysts and the PAH universe
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.

Systems pharmacology of the endocannabinoid system
In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Systems Pharmacology
The Systems Pharmacology group is headed by Prof. Piet Hein van der Graaf. Systems Pharmacology is the quantitative analysis of the dynamic interactions between drugs and a biological system to understand the behaviour of the system as a whole, as opposed to the behaviour of its individual constituents;…

Concurrent Systems
In modern information systems, a large number of different components are often active simultaneously. This phenomenon - known as concurrency - underlies not only the functioning of computer systems but of any system in which many processes take place at the same time.

Isotopes and the characterization of extrasolar planets
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.

Astrophysical plasma modeling of the hot Universe: Advances and challenges in high-resolution X-ray spectroscopy
Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.
