• Not so smooth after all: resolving dust and gas structures in protoplanetary disks Research output

  A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

• Searching explanations for mysterious structures in protoplanetary disks News - 12 December 2019

  In the discs of dust and gasses around young stars, mysterious structures occur. Together with professor Ewine van Dishoeck, PhD student Paolo Cazzoletti investigate how we can explain these forms, such as rings, spirals and holes. On 12 December, he will defend his thesis.

• Inextricable ties between chemical complexity and dynamics of embedded protostellar regions Research output

  Promotor: E. F. van Dishoeck, Co-promotor: C. Walsh

• Linking simple molecules to grain evolution across planet-forming disks Research output

  Planets are formed in disks of gas and dust around young stars.

• Mining the kinematics of discs to hunt for planets in formation Research output

  Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

• Imaging the water snow line within a protoplanetary disc News - 13 July 2016

  Research using the ALMA telescope by scientists including Leiden's John Tobin and Steven Bos has produced the first images of the water snow line within a protoplanetary disc. Publication in Nature on 14 July.

• Chemistry in embedded disks: setting the stage for planet formation Research output

  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.

• Mind the gap: gas and dust in planet-forming disks Research output

  Promotores: Prof.dr. E.F. van Dishoeck, Prof.dr. C.P. Dullemond

• Uncovering the ingredients for planet formation Research output

  This thesis discusses the physical and chemical processes than influence the composition of forming planets.

• Turtles all the way down: multiscale simulations connecting star and planet formation Research output

  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.

• Freezing conditions in warm disks: snowlines and their effect on the chemical structure of planet-forming disks Research output

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

• In Memoriam Emeritus Professor G. van Dijk News - 22 April 2022

  Gerrit van Dijk was born on 14th August 1939 in Kampen. He studied Mathematics in Utrecht where he also received his PhD in 1969 on the thesis ‘Spherical functions on the p-adic group PGL(2)’. His supervisor was prof. dr. T.A. Springer. The academic year 1969-1970 he spent in Princeton, at the Institute…

• Ice and Gas in Protostellar Clouds and Planet-forming Disks Research output

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