The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve
Y. -Z. Cai, A. Pastorello, R. Chiba +65
We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…
Circumbinary Discs as the Origin of Circumstellar Material around Interacting H-poor Supernovae and Fast Blue Optical Transients
Ryotaro Chiba, Semih Tuna, Brian D. Metzger +1
Around 10 % of hydrogen-poor supernovae explode inside compact ( cm), massive () circumstellar material (CSM), signalling an episode of e…
A thermonuclear supernova interacting with hydrogen- and helium-deficient circumstellar material. SN 2020aeuh as a SN Ia-CSM-C/O?
K. Tsalapatas, J. Sollerman, R. Chiba +20
Identifying the progenitors of thermonuclear supernovae (Type Ia supernovae; SNe Ia) remains a key objective in contemporary astronomy. The rare subclass of SNe Ia that interacts w…
Hydrodynamic Modelling of Early Peaks in Type Ibc Supernovae with Circumstellar Interaction
Ryotaro Chiba, Takashi J. Moriya
Recent high-cadence transient surveys have uncovered a subclass of Type Ibc supernovae (SNe) that exhibit an early, blue peak lasting a few days before the main, radioactively powe…
Characterisation of Supernovae Interacting with Dense Circumstellar Matter with a Flat Density Profile
Ryotaro Chiba, Takashi J. Moriya
Interaction between supernova (SN) ejecta and dense circumstellar medium (CSM) with a flat density structure () was recently proposed as a possible mechan…
