The bright long-lived Type II SN 2021irp powered by aspherical circumstellar material interaction (I): Revealing the energy source with photometry and spectroscopy
T. M. Reynolds, T. Nagao, R. Gottumukkala +20
Some core-collapse supernovae (CCSNe) are too luminous and radiate too much total energy to be powered by the release of thermal energy from the ejecta and radioactive-decay energy…

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…
