LBV phenomenon and binarity: The environment of HR Car
A. Mehner, S. Janssens, C. Agliozzo +7
Luminous blue variable stars (LBVs) are of great interest in massive-star evolution as they experience very high mass-loss episodes within short periods of time. HR Car is a famous…
Numerical experiments to help understand cause and effect in massive star evolution
Eoin Farrell, Jose Groh, Georges Meynet +1
The evolution of massive stars is affected by a variety of physical processes including convection, rotation, mass loss and binary interaction. Because these processes modify the i…
The origins of low-luminosity supernovae: the case of SN 2016bkv
Maxime Deckers, Jose H. Groh, Ioana Boian +1
We investigate the low-luminosity supernova SN 2016bkv and its peculiar early-time interaction. For that, we compute radiative transfer models using the CMFGEN code. Because SN 201…
The Early Phases of Supernova 2020pni: Shock-Ionization of the Nitrogen-Enriched Circumstellar Material
G. Terreran, W. V. Jacobson-Galan, J. H. Groh +20
We present multiwavelength observations of the Type II SN 2020pni. Classified at days after explosion, the object showed narrow (FWHM $<250\,\textrm{km}\,\textrm{s}^{-1}…
Ionizing photon production of Population III stars: effects of rotation, convection, and initial mass function
Laura J. Murphy, Jose H. Groh, Eoin Farrell +5
The first stars are thought to be one of the dominant sources of hydrogen reionization in the early Universe, with their high luminosities and surface temperatures expected to driv…
Convective core sizes in rotating massive stars: I. Constraints from solar metallicity OB field stars
S. Martinet, G. Meynet, S. Ekström +11
Spectroscopic studies of Galactic O and B stars show that many stars with masses above 8 M are observed in the HR diagram just beyond the Main-Sequence (MS) band predicte…
