Graduate School of Science


PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

A detailed description of the research projects can be found on the website of the Leiden Observatory.


Specific requirements of the PhD programme are determined in agreement with NOVA, the Netherlands Research School in Astronomy. The PhD candidates attend summer and/or winter schools, and actively participate in international meetings as a part of their training. Many of the research projects involve international collaborations. Working visits and observations trips may be required. The PhD thesis is written in English, the language commonly used in the research groups.

MSc degree

An MSc degree is required for admission to the PhD programme. If appropriate, the PhD project will be a continuation of an MSc research project. Every year, the Leiden Observatory has paid positions available for PhD candidates, that are filled on a merit basis.


A paid position includes limited assistance in undergraduate teaching. It may also be possible to enter the PhD programme with self-obtained grants. Grants must provide for costs of living and for a bench fee.
