Spectropolarimetric Evolution Reveals Dual-Axis Ejecta in the Atypical Magnetar-Powered SN 2012au
Sabrina DeSoto, JenniferL. Hoffman, G. Grant Williams +7
We present six epochs of optical spectropolarimetric observations of the unique and slow-evolving Type Ib supernova (SN) 2012au, between 0 and 295 days post R-band maximum. The pol…
Spectropolarimetry of SN 2023ixf reveals both circumstellar material and helium core to be aspherical
Manisha Shrestha, Sabrina DeSoto, David J. Sand +33
We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc.…
Spectropolarimetric modeling of interacting Type II supernovae. Application to early-time observations of SN1998S
Luc Dessart, Douglas C. Leonard, Sergiy S. Vasylyev +1
High-cadence surveys of the sky are revealing that a large fraction of red-supergiant (RSG) stars, which are progenitors of Type II-Plateau (II-P) supernovae (SNe), explode within…
Calcium-rich gap transients in the remote outskirts of galaxies
Mansi M. Kasliwal, S. R. Kulkarni, Avishay Gal-Yam +25
From the first two seasons of the Palomar Transient Factory, we identify three peculiar transients (PTF09dav, PTF10iuv, PTF11bij) with five distinguishing characteristics: peak lum…
Evidence for Type Ia Supernova Diversity from Ultraviolet Observations with the Hubble Space Telescope
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +93
We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Sur…
