The 91T/99aa-like Type Ia Supernova 2019vrq, Part II: 3D, Non-LTE, Low-Amplitude, Pulsating Delayed-Detonation Models of a Promising Standard Candle
Peter Hoeflich, Yi Yang, J. Craig Wheeler +11
We analyze the overluminous, 91T/99aa-like Type~Ia SN 2019vrq, based on light curves(LCs) and spectropolarimetric time-series. We employ 3D-radiation-hydrodynamical, full non-LTE s…
JWST Medium-Resolution Infrared Spectroscopy of SN 2022acko: Tracing Molecule Formation in the Nebular Phase
K. Medler, T. Mera, C. Ashall +28
The Type II supernova (SN II) SN 2022acko was the first to be spectroscopically observed by the James Webb Space Telescope (). Here, we analyze SN 2022acko's second…
Spatial and spectral constraints on resolved mass-loss of the massive Post-RSG star IRAS 17163-3907 and its Fried Egg Nebula
E. Koumpia, A. Cikota, W. -J. de Wit +12
The fate of massive stars during the latest stages of their evolution is highly dependent on their mass-loss rate and geometry. These processes have a significant influence on star…
Line Polarization of Si II 6355 Å in Type Ia Supernovae: A New Statistical Approach to Probe the Explosion Physics and Diversity
Aleksandar Cikota, Peter Hoeflich, Dietrich Baade +6
Spectropolarimetry provides a unique probe of ejecta asphericities, offering direct insights into the underlying explosion physics of Type Ia supernovae (SNe Ia). We analyze the st…
An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi
Yi Yang, Xudong Wen, Lifan Wang +18
The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…
Moonlit sky polarization patterns from Cerro Paranal
B. Pereira, S. Gonzalez-Gaitan, A. M. Mourao +5
We investigate the polarization patterns from the moonlit sky as observed from the European Southern Observatory at Cerro Paranal. The moonlit sky background can be significant in…
