Spectroscopy of AT 2016blu's recurring supernova impostor outbursts

Mojgan Aghakhanloo, Nathan Smith, Jennifer E. Andrews +7

We present spectra of the supernova (SN) impostor AT 2016blu spanning over a decade. This transient exhibits quasiperiodic outbursts with a 113 d period, likely triggered by…

Circumstellar Interaction in the Ultraviolet Spectra of SN 2023ixf 14-66 Days After Explosion

K. Azalee Bostroem, David J. Sand, Luc Dessart +20

SN 2023ixf was discovered in M101 within a day of explosion and rapidly classified as a Type II supernova with flash features. Here we present ultraviolet (UV) spectra obtained wit…
