Luminous Type II Short-plateau SN 2023ufx: Asymmetric Explosion of a Partially Stripped Massive Progenitor

We present supernova (SN) 2023ufx, a unique Type IIP SN with the shortest known plateau duration ( t _PT ∼ 47 days), a luminous V -band peak ( M _V = −​​​​​​18.42 ± 0.08 mag), and a rapid early decline rate ( s 1 = 3.47 ± 0.09 mag (50 days) ^−1 ). By comparing observed photometry to a hydrodynamic M...
