英文摘要Extensive and independent observations of Type Ia supernova (SN Ia) SN 2013dy are presented, including a larger set of UBVRI photometry and optical spectra from a few days before the peak brightness to 200 days after explosion, and ultraviolet (UV) photometry spanning from t approximate to -10 days to t approximate to +15 days refers to the B band maximum. The peak brightness (i.e., MB = 19.65 +/- 0.40 mag; Lmax = [1.95 +/- 0.55] x 10(43) erg s(-1)) and the mass of synthesized Ni-56 (i.e., M(Ni-56) = 0.90 +/- 0.26 M.) are calculated, and they conform to the expectation for an SN Ia with a slow decline rate (i.e., Delta m15(B) = 0.90 +/- 0.03 mag). However, the near infrared (NIR) brightness of this SN (i.e., M-H = 17.33 +/- 0.30 mag) is at least 1.0 mag fainter than usual. Besides, spectroscopy classification reveals that SN 2013dy resides on the border of "core normal" and "shallow silicon" subclasses in the Branch et al. classification scheme, or on the border of the "normal velocity" SNe Ia and 91T/99aa-like events in the Wang et al. system. These suggest that SN 2013dy is a slow-declining SN Ia located on the transitional region of nominal spectroscopic subclasses and might not be a typical normal sample of SNe Ia.
