Abstract:
SN 2013dy is a Type Ia supernova (SN Ia) for which we have compiled an
extraordinary data set spanning from 0.1 to ∼500d after explosion. We
present 10 epochs of ultraviolet (UV) through near-infrared (NIR) spectra
with Hubble Space Telescope/Space Telescope Imaging Spectrograph, 47 epochs
of optical spectra (15 of them having high resolution), and more than
500 photometric observations in the BVrRiIZYJH bands. SN 2013dy has a
broad and slowly declining light curve (Δm15(B)=0.92mag),
shallow SiII λ6355 absorption, and a low velocity gradient. We
detect strong CII in our earliest spectra, probing unburned progenitor
material in the outermost layers of the SN ejecta, but this feature
fades within a few days. The UV continuum of SN 2013dy, which is
strongly affected by the metal abundance of the progenitor star,
suggests that SN 2013dy had a relatively high-metallicity progenitor.
Examining one of the largest single set of high-resolution spectra for
an SN Ia, we find no evidence of variable absorption from circumstellar
material. Combining our UV spectra, NIR photometry, and high-cadence
optical photometry, we construct a bolometric light curve, showing
that SN 2013dy had a maximum luminosity of 10.0+4.8-3.8x1042erg/s.
We compare the synthetic light curves and spectra of several models to
SN 2013dy, finding that SN 2013dy is in good agreement with a
solar-metallicity W7 model.
Description:
We obtained broad-band BVRI photometry of SN 2013dy with the 0.76m
Katzman Automatic Imaging Telescope (KAIT; Filippenko et al.
2001ASPC..246..121F 2001ASPC..246..121F). The multiband images were observed with the
KAIT4 filter set from -16d to +337d relative to B-band maximum
(MJD=56501.105). We also obtained riZYJH photometry of SN 2013dy with
the multichannel Reionization And Transients InfraRed camera (RATIR;
Butler et al. 2012SPIE.8446E..10B 2012SPIE.8446E..10B) mounted on the 1.5m Johnson telescope
at the Mexican Observatorio Astronomico Nacional on Sierra San Pedro
Martir in Baja California, Mexico (Watson et al. 2012SPIE.8444E..5LW).
Typical observations include a series of 80s exposures in the ri bands
and 60s exposures in the ZYJH bands, with dithering between exposures.
