Molecular inheritance from cloud to disk: a story of complex organics and accretion shocks
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.

Tuning in to star-planet interactions at radio wavelengths
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.

and ‘everyday practices’: An analysis of extreme right and Islamic State women-only forums
A growing amount of literature is being devoted to interrogating gendered dynamics in both violent extremism and terrorism, contributing to the integration of international and feminist security. This includes how such dynamics can shape differences in the motivations and participation of women and…

Face-to-face politics: why small states matter
Political scientist Wouter Veenendaal received an NWO Veni grant for his research on the political stability of small states. 'I find small states fascinating, they are almost always excluded from comparative research, while in fact they often challenge existing theories in political science.'
