K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
Light-echoes from the plateau in Eta Carinae's Great Eruption reveal a two-stage shock-powered event
Nathan Smith, Jennifer E. Andrews, Armin Rest +7
We present multi-epoch photometry and spectroscopy of a light echo from eta Carinae's 19th century Great Eruption. This echo shows a steady decline over a decade, sampling the 1850…
Exceptionally fast ejecta seen in light echoes of Eta Carinae's Great Eruption
Nathan Smith, Armin Rest, Jennifer E. Andrews +7
In our ongoing study of eta Carinae's light echoes, there is a relatively bright echo that has been fading slowly, reflecting the 1845-1858 plateau of the eruption. A separate pape…
Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-Degenerate Double-Detonation Type Ia Supernovae
Ken J. Shen, Douglas Boubert, Boris T. Gänsicke +23
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progeni…
ASASSN-15nx: A luminous Type II supernova with a "perfect" linear decline
Subhash Bose, Subo Dong, C. S. Kochanek +24
We report a luminous Type II supernova, ASASSN-15nx, with a peak luminosity of M_V=-20 mag, that is between typical core-collapse supernovae and super-luminous supernovae. The post…
SN 2017ein and the Possible First Identification of a Type Ic Supernova Progenitor
Schuyler D. Van Dyk, WeiKang Zheng, Thomas G. Brink +11
We have identified a progenitor candidate in archival Hubble Space Telescope (HST) images for the Type Ic SN 2017ein in NGC 3938, pinpointing the candidate's location via HST Targe…
Strong late-time circumstellar interaction in the peculiar supernova iPTF14hls
Jennifer E. Andrews, Nathan Smith
We present a moderate-resolution spectrum of the peculiar Type II supernova iPTF14hls taken on day 1153 after discovery. This spectrum reveals the clear signature of shock interact…
SN2013fs and SN2013fr: Exploring the circumstellar-material diversity in Type II supernovae
Christopher Bullivant, Nathan Smith, G. Grant Williams +12
We present photometry and spectroscopy of SN2013fs and SN2013fr in the first 100 days post-explosion. Both objects showed transient, relatively narrow H emission lines character…
