Metal-Rich RRc stars in the Carnegie RR Lyrae Survey
Christopher Sneden, George W. Preston, Juna A. Kollmeier +6
We describe and employ a stacking procedure to investigate abundances derived from the low S/N spectra obtained in the Carnegie RR Lyrae Survey (CARRS; Kollmeier et al. 2013). We f…
Light Curves of the Neutron Star Merger GW170817/SSS17a: Implications for R-Process Nucleosynthesis
M. R. Drout, A. L. Piro, B. J. Shappee +41
On 2017 August 17, gravitational waves were detected from a binary neutron star merger, GW170817, along with a coincident short gamma-ray burst, GRB170817A. An optical transient so…
The Unprecedented Properties of the First Electromagnetic Counterpart to a Gravitational Wave Source
Matthew R. Siebert, Ryan J. Foley, Maria R. Drout +15
We discovered Swope Supernova Survey 2017a (SSS17a) in the LIGO/Virgo Collaboration (LVC) localization volume of GW170817, the first detected binary neutron star (BNS) merger, only…
The Old Host-Galaxy Environment of SSS17a, the First Electromagnetic Counterpart to a Gravitational Wave Source
Y. -C. Pan, C. D. Kilpatrick, J. D. Simon +16
We present an analysis of the host-galaxy environment of Swope Supernova Survey 2017a (SSS17a), the discovery of an electromagnetic counterpart to a gravitational wave source, GW17…
Type II supernova spectral diversity II: Spectroscopic and photometric correlations
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +7
We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe~II), during the pho…
Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23
We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
