A 12.4 day periodicity in a close binary system after a supernova

Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37

Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…

A 9-Month Hubble Space Telescope Near-UV Survey of M87. I. Light and Color Curves of 94 Novae, and a Re-determination of the Nova Rate

Michael M. Shara, Alec M. Lessing, Rebekah Hounsell +10

M87 has been monitored with a cadence of 5 days over a 9 month-long span through the near-ultraviolet (NUV:F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of t…

Long-rising Type II Supernovae in the Zwicky Transient Facility Census of the Local Universe

Tawny Sit, Mansi M. Kasliwal, Anastasios Tzanidakis +25

SN 1987A was an unusual hydrogen-rich core-collapse supernova originating from a blue supergiant star. Similar blue supergiant explosions remain a small family of events, and are b…

A Systematic Study of Ia-CSM Supernovae from the ZTF Bright Transient Survey

Yashvi Sharma, Jesper Sollerman, Christoffer Fremling +35

Among the supernovae (SNe) that show strong interaction with the circumstellar medium, there is a rare subclass of Type Ia supernovae, SNe Ia-CSM, that show strong narrow hydrogen…

The prevalence and influence of circumstellar material around hydrogen-rich supernova progenitors

Rachel J. Bruch, Avishay Gal-Yam, Ofer Yaron +44

Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor stars o…
