SN2023ixf: ultraviolet-to-infrared radiative-transfer modeling of the nebular-phase evolution until 1000 days
Luc Dessart, Wynn V. Jacobson-Galan, K. Azalee Bostroem +6
We present non-local thermodynamic equilibrium radiative-transfer modeling of SN2023ixf during the nebular phase out to 1000d, using the same ejecta that matched its photospheric e…
SN2023ixf: Radiative-transfer modeling of the photospheric phase evolution from the ultraviolet to the infrared
Luc Dessart, Wynn V. Jacobson-Galan, K. Azalee Bostroem +4
SN2023ixf, a Type II supernova (SN) showing early signs of interaction with circumstellar material (CSM), has been observed with unprecedented detail across the electromagnetic spe…
A modeling perspective on the diversity of red-supergiant stars exploding within circumstellar material
Luc Dessart, W. V. Jacobson-Galan
With the ever faster cadence of untargeted surveys of the sky, the supernova (SN) community will capture in the coming years a growing number of shock breakouts in red-supergiant (…
Infrared diagnostics of late-time core-collapse supernova spectra
Luc Dessart
We present nonlocal thermodynamic equilibrium radiative transfer calculations of red supergiant and He-star explosions, extending previous work to focus on the infrared emission fr…
Mass-transferring binary stars as progenitors of interacting hydrogen-free supernovae
Andrea Ercolino, Harim Jin, Norbert Langer +1
Stripped-envelope supernovae (SNe) are H-poor transients produced at the end of the life of massive stars that previously lost their H-rich envelope. Their progenitors are thought…
Interacting supernovae
Luc Dessart
Modern photometric surveys of the sky suggest that many, perhaps most supernovae (SNe) associated with the explosion of massive stars are influenced at an appreciable level by thei…
The look of high-velocity red-giant star collisions
Luc Dessart, Taeho Ryu, Pau Amaro Seoane +1
High-velocity stellar collisions driven by a supermassive black hole (BH) or BH-driven disruptive collisions, in dense, nuclear clusters can rival the energetics of supergiant star…
The variable stellar wind of Rigel probed at high spatial and spectral resolution
O. Chesneau, A. Kaufer, O. Stahl +5
We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and it…
