Student schoont archiefdata op en onthult twee stellaire cocons
Tijdens het bestuderen van zestien jaar aan meetgegevens van jonge sterren ontdekte de Leidse masterstudent Sam de Regt dat twee van die sterren nog gehuld waren in geboortewolken. Nog niet eerder bracht iemand deze twee sterren zo scherp in beeld. Hij publiceert zijn opschoonmethode en de nieuwe afbeeldingen…

Goed werkgeverschap in relatie tot medewerkerswelzijn
Goed werkgeverschap is net als goed werknemerschap een open norm. Daarmee is het onduidelijk en onzeker waar werkgevers zich op dienen te richten en welke rechten (en plichten) werknemers hebben in dat verband. De doelstelling van dit onderzoek is om invulling te geven aan de norm goed werkgeverschap…

Hoe herken je de atmosfeer van buitenaardse lavawerelden?
In de afgelopen 30 jaar zijn er ruim 5000 planeten ontdekt buiten ons zonnestelsel. Een veelvoorkomende exoplaneet is de lavawereld, een hete superaarde met oceanen van vloeibaar lava. Mantas Zilinskas ontwikkelde modellen om mogelijke atmosferen daarvan te simuleren. Die simulaties bieden houvast voor…

Astronomen zien ster met stofschijf die nog steeds groeit
Een internationaal team van sterrenkundigen waaronder ook Leidse wetenschappers publiceert het beeld van een jonge ster met een omringende stofschijf die nog steeds gevoerd wordt vanuit de omgeving. Het verschijnsel rond de ster SU Aur kan verklaren waarom zoveel exoplaneten niet netjes uitgelijnd zijn…

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.

High-contrast imaging polarimetry of exoplanets and circumstellar disks
Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Untangling cosmic collisions: a study of particle acceleration and magnetic fields in merging galaxy clusters
On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

Extremely loud & incredibly far: observing radio bright AGN into the cosmic dawn
In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Leiden Law students are looking forward to the lawyer of the future
As Leiden Law students, we are now in the digital age, 'where we believe law and technology should go together.' After all, for us, it is important to look beyond trodden paths of established legal knowledge. The books on law and case law surely will not be sufficient for the lawyer of the future. That…

The interplay between stars, gas and dust in faint star-forming galaxies
When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.
