Nested, asymmetric H-He circumstellar shells in the Type Icn/Ibn SN 2024abvb
The INTEL Collaboration, J. P. Anderson, C. Aster +17
Interacting transients probe mass loss in the final stages of stellar evolution; however, the geometry and timing of multi-episode mass loss remain poorly constrained. SN 2024abvb…

Revisiting the unification of tidal disruption events with polarimetry
H. C. I. Wichern, G. Leloudas, M. Pursiainen +10
Tidal disruptions of stars by supermassive black holes produce multi-wavelength emission, of which the optical emission is of ambiguous origin. A unification scenario of tidal disr…

Evidence for bipolar explosions in Type IIP supernovae
T. Nagao, K. Maeda, S. Mattila +16
Recent observations of core-collapse supernovae (SNe) suggest aspherical explosions. Globally aspherical structures in SN explosions are regarded as the key for understanding their…
