By *ivskuleuven* on 1 July 2026
*Location:* Armagh Observatory

*Description:* The Armagh Observatory and Planetarium (AOP) are seeking an
enthusiastic theorist to join the 5 year ERC-funded ION-FLUX project, which
aims to test whether very massive stars played a dominant role in cosmic
reionisation. The project combines stellar atmosphere and wind modelling
with stellar evolution calculations, and extends to hydrodynamical studies
of the circumstellar medium of massive stars prior to explosion. You will
join a collaborative team that combines detailed modelling with direct
comparison to observational data.

ION-FLUX aims to establish a new predictive framework for the atmospheres,
winds, and ionising output of (very) massive stars, combining
hydrodynamically consistent modelling with stellar evolution. A central
goal is to connect stellar winds to the build-up of the circumstellar
medium, and to determine the environments in which massive stars end their
lives, either collapsing to black holes or exploding as supernovae.

By linking stellar atmospheres, mass loss, and circumstellar structure, the
project will provide new insights into stellar feedback, transient
phenomena, and the role of massive stars in shaping galaxies and the early
Universe.

The successful candidate will play a leading role in developing
next-generation hydrodynamical stellar atmosphere models and exploring
their implications for stellar evolution and feedback. This work will
connect directly to observational programmes, including large surveys of
massive stars at low metallicity.

Situated in Armagh, Northern Ireland, AOP delivers internationally
recognised research in astronomy and related sciences and vibrant
educational and outreach programmes for all ages. Research staff work on a
range of topics, from the study of our Sun and Solar System to distant
galaxies, has access to all UK national observing facilities, including
ESO, ALMA and ESA, and participate in several international projects such
as XSHOOTU, WEAVE, GOTO, I-LOFAR and CTA.
