Rotation at the Fully Convective Boundary: Insights from Wide WD + MS Binary Systems
Federica Chiti, Jennifer L. van Saders, Tyler M. Heintz +5
Gyrochronology, a valuable tool for determining ages of low-mass stars where other techniques fail, relies on accurate calibration. We present a sample of 185 wide ( au) wh…
Probing pre-supernova mass loss in double-peaked Type Ibc supernovae from the Zwicky Transient Facility
Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +34
Eruptive mass loss of massive stars prior to supernova (SN) explosion is key to understanding their evolution and end fate. An observational signature of pre-SN mass loss is the de…
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…
A search for relativistic ejecta in a sample of ZTF broad-lined Type Ic supernovae
Alessandra Corsi, Anna Y. Q. Ho, S. Bradley Cenko +23
The dividing line between gamma-ray bursts (GRBs) and ordinary stripped-envelope core-collapse supernovae (SNe) is yet to be fully understood. Observationally mapping the variety o…
The Hydrogen-Poor Superluminous Supernovae from the Zwicky Transient Facility Phase-I Survey: I. Light Curves and Measurements
Z. H. Chen, Lin Yan, T. Kangas +40
During the Zwicky Transient Facility (ZTF) Phase-I operation, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than three years, making up the largest sa…
Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
A large fraction of hydrogen-rich supernova progenitors experience elevated mass loss shortly prior to explosion
Rachel J. Bruch, Avishay Gal-Yam, Steve Schulze +43
Spectroscopic detection of narrow emission lines traces the presence of circumstellar mass distributions around massive stars exploding as core-collapse supernovae. Transient emiss…
Spectroscopy of the first resolved strongly lensed Type Ia supernova iPTF16geu
J. Johansson, A. Goobar, S. H. Price +14
We report the results from spectroscopic observations of the multiple images of the strongly lensed Type Ia supernova (SN Ia), iPTF16geu, obtained with ground based telescopes and…
The Zwicky Transient Facility Census of the Local Universe I: Systematic search for Calcium rich gap transients reveal three related spectroscopic sub-classes
Kishalay De, Mansi M. Kasliwal, Anastasios Tzanidakis +47
(Abridged) Using the Zwicky Transient Facility alert stream, we are conducting a large campaign to spectroscopically classify all transients occurring in galaxies in the Census of…
Early Ultra-Violet observations of type IIn supernovae constrain the asphericity of their circumstellar material
Maayane T. Soumagnac, Eran O. Ofek, Jingyi Liang +41
We present a survey of the early evolution of 12 Type IIn supernovae (SNe IIn) in the Ultra-Violet (UV) and visible light. We use this survey to constrain the geometry of the circu…
The Zwicky Transient Facility Bright Transient Survey I: Spectroscopic Classification and the Redshift Completeness of Local Galaxy Catalogs
U. C. Fremling, A. A. Miller, Y. Sharma +37
The Zwicky Transient Facility (ZTF) is performing a three-day cadence survey of the visible Northern sky (~3). The transient candidates found in this survey are announced via pu…
ZTF Early Observations of Type Ia Supernovae I: Properties of the 2018 Sample
Yuhan Yao, Adam A. Miller, S. R. Kulkarni +32
Early-time observations of Type Ia supernovae (SNe Ia) are essential to constrain their progenitor properties. In this paper, we present high-quality light curves of 127 SNe Ia dis…
The luminous and rapidly evolving SN 2018bcc: Clues toward the origin of Type Ibn SNe from the Zwicky Transient Facility
