Together with Rijksmuseum Boerhaave, the Lorentz Center organizes the public event ‘Weighing Stars’.


Weighing Stars

Since the dawn of mankind, people looked into the night sky and wondered what stars are. Stars told people when to saw and when to harvest and also how to navigate across seas.


Today, we know that stars are cosmic powerhouses that have transformed the pristine Universe into the one we live in today. For example, stars were responsible for the re-brightening of the Universe after the Dark Ages and have produced most of the chemical elements on Earth such as the oxygen we breathe in everyday or the iron in our blood.


The key for understanding the evolution and final fates of stars is their mass. But how do we measure these masses and why are they so important? Fabian Schneider will take you on a journey to the stars and explore what the mass has to do with whether a star will explode in a supernova or not.



Dr. Fabian Schneider is a Gliese Fellow at the Zentrum für Astronomie of the University of Heidelberg based at the Astronomisches Recheninstitut (ARI). He is also a visiting scientist at the Heidelberg Institute for Theoretical Studies.


In his work, he studies the evolution and final fates of stars to understand their role in the cosmos. His work is mostly of theoretical nature and he makes heavy use of stellar evolution codes, population synthesis models and Bayesian statistical methods.


This public lecture is part of a collaboration between Rijksmuseum Boerhaave and the Lorentz Center, in which internationally respected experts address a wide audience on topics of societal and/or scientific importance.

Rijksmuseum Boerhaave

Rijksmuseum Boerhaave is the Dutch National Museum for the History of Science and Medicine. Its aim is to improve the societal support base for science in the Netherlands. Rijksmuseum Boerhaave always seeks to connect its activities with current events  (


The Lorentz Center

The Lorentz Center is a Dutch workshop center, located at Leiden University. It organizes international scientific workshops in all disciplines, to promote innovative research at the scientific frontiers as well as on complex societal challenges. (
