X-ray emission from massive stars: lessons learned and remaining mysteries [PDF]

open access: yes, 2021
Nearly all types of massive stars are known to display X-ray emission at some level. Tremendous insight into this phenomenon has been gained thanks to the sensitivity of the current generation of X-ray satellites and X-ray observations are nowadays an ...

Neutrino radiation hydrodynamics in hot and dense nuclear matter and the role of microphysics in simulations of massive stars [PDF]

open access: yes, 2010
The main results of my doctoral studies were obtained from core collapse simulations of massive stars using a numerical model based on radiation hydrodynamics and three-flavour Boltzmann neutrino transport in spherical symmetry.

The VLT-FLAMES survey of massive stars: observations in the Galactic clusters NGC3293, NGC4755 and NGC6611 [PDF]

open access: yes, 2005
We introduce a new survey of massive stars in the Galaxy and the Magellanic Clouds using the Fibre Large Array Multi- Element Spectrograph ( FLAMES) instrument at the Very Large Telescope ( VLT).

New Candidate Massive Clusters from 2MASS [PDF]

open access: yes, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

The role of neutrinos in explosive nucleosynthesis in core collapse supernova models with neutrino transport [PDF]

open access: yes, 2007
The problem of core collapse supernova explosions is long standing and attempts to understand the mechanism have been ongoing. On one hand, a full understanding of the underlying mechanism is still pending.

Asteroseismology of massive stars: new insights of stellar interiors from their pulsations

open access: yes, 2021
Massive stars are important metal factories which provide energy and chemical feedback to their surroundings. However, stellar evolution models currently contain large theoretical uncertainties for physical mechanisms at work in the deep interiors of ...

GES. OB stars in the Carina Nebula [Dataset]

open access: yes, 2023
The Carina Nebula is one of the major massive star-forming regions in the Galaxy. Its relatively nearby distance (2.35kpc) makes it an ideal laboratory for the study of massive star formation, structure and evolution both for individual stars and stellar

Modelling and observations of molecules in discs around young stars [PDF]

open access: yes, 2013
This thesis contains a study of molecules within circumstellar discs around young stars. Firstly, the chemistry of a disc around a young, Class 0 protostar is modelled.

What can magnetic early B-type stars tell us about early B-type stars in general?

open access: yes, 2016
Some magnetic early B-type stars display Hα emission originating in their Centrifugal Magnetospheres (CMs). To determine the rotational and magnetic properties necessary for the onset of emission, we analyzed a large spectropolarimetric dataset for a ...
