Advancing Heliophysics and Space Weather Modeling through Open Science
C. Corti, M. M. Kuznetsova, M. A. Reiss +85
We present a community-wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potenti…
Multi-dimensional, time-dependent approximate NLTE unified model atmospheres with winds for hot, massive stars
Dwaipayan Debnath, Jon O. Sundqvist, Nicolas Moens +3
Multi-dimensional unified model atmospheres with winds of massive stars have so far been studied under the assumption of equal flux, Planck, and energy weighted mean opacities, whi…
Spectral synthesis of 3D unified model atmospheres with winds for O stars
L. Delbroek, J. O. Sundqvist, D. Debnath +5
Spectroscopic studies of massive and luminous O-type stellar atmospheres and winds have primarily been done by using 1D, spherically symmetric and stationary models. Both observati…
2D unified atmosphere and wind simulations for a grid of O-type stars
Nicolas Moens, Dwaipayan Debnath, Olivier Verhamme +4
The atmospheres of massive O-type stars (O stars) are dynamic, turbulent environments resulting from radiatively driven instabilities over the iron bump, located slightly beneath t…
An on-the-fly line-driven-wind iterative mass-loss estimator (LIME) for hot, massive stars of arbitrary chemical compositions
J. O. Sundqvist, D. Debnath, F. Backs +7
Mass-loss rates from hot, massive stars are important for a range of astrophysical applications. We present \href{https://lime.ster.kuleuven.be/}{LIME}, a fast, efficient, and easy…
Near-Eddington mass loss of hydrogen-rich Wolf-Rayet stars
Roel R. Lefever, Andreas A. C. Sander, Matheus Bernini-Peron +6
Context. Very massive clusters and regions of intense star formation such as the center of our Milky Way contain young, hydrogen-burning stars very close to the Eddington Limit. Fo…
