Description

We have obtained photometry and spectra of SN 1991T which extend more than 1000 days past maximum light, by far the longest a SN Ia has been followed. Although SN 1991T exhibited nearly photometric behavior in the first 400 days following maximum, by 600 days its decline had slowed, and by 950 days the supernova brightness was consistent with a constant apparent magnitude of m_B_ = 21.30. Spectra near maximum showed minor variations on the SN Ia theme which grew less conspicuous during the...[Show more]
