Nebular Spectroscopy of Kepler's Brightest Supernova
G. Dimitriadis, C. Rojas-Bravo, C. D. Kilpatrick +9
We present late-time (240-260 days after peak brightness) optical photometry and nebular (+236 and +264 days) spectroscopy of SN 2018oh, the brightest Type Ia supernova (SN I…
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…
Sub-percent Photometry: Faint DA White Dwarf Spectophotometric Standards for Astrophysical Observatories
Gautham Narayan, Thomas Matheson, Abhijit Saha +18
We have established a network of 19 faint (16.5 mag 19 mag) northern and equatorial DA white dwarfs as spectrophotometric standards for present and future wide-field observ…
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…
Seeing Double: ASASSN-18bt Exhibits a Two-Component Rise in the Early-Time K2 Light Curve
B. J. Shappee, T. W. -s. Holoien, M. R. Drout +109
On 2018 Feb. 4.41, the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered ASASSN-18bt in the K2 Campaign 16 field. With a redshift of z=0.01098 and a peak apparent magnit…
A Fast-Evolving, Luminous Transient Discovered by K2/Kepler
A. Rest, P. M. Garnavich, D. Khatami +12
For decades optical time-domain searches have been tuned to find ordinary supernovae, which rise and fall in brightness over a period of weeks. Recently, supernova searches have im…
