Type Ia Supernova Light Curves
The diversity of Type Ia supernova (SN Ia) photometry is explored using a grid of 130 one-dimensional models. It is shown that the observable properties of SNe Ia resulting from Chandrasekhar-mass explosions are chiefly determined by their final composition and some measure of “mixing” in the explosion. A grid of final compositions is explored including essentially all combinations of Ni, stabl...
متن کاملTHE LIGHT CURVES OF TYPE Ia SUPERNOVA 2004fu
CCD UBV RI photometry is presented for type Ia supernova 2004fu in NGC 6949. The light and colour curves are typical for this class of objects, absolute magnitude at maximum and decline rate are in agreement with the relationship between these parameters, established for SNe Ia. SN 2004fu was discovered by Arbour (2004) on unfiltered CCD images taken with a 0.3-m Schmidt-Cassegrain reflector on...
متن کاملChang-Refsdal Microlensed Type Ia Supernova Light Curves
A description of the light curves of microlensed Type Ia supernovae (SNe Ia) as extended and expanding sources is presented. We give examples of what microlensing by stellar-mass Chang-Refsdal lenses can do to a small percentage of supernova light curves. We find that in addition to overall brightening, significant changes in light–curve shapes can also occur. Peaks can be distorted, plateaus c...
متن کاملMeasuring Type Ia Supernova Distances and Redshifts From Their Multi-band Light Curves
The distance and redshift of a type Ia supernova can be determined simultaneously through its multi-band light curves. This fact may be used for imaging surveys that discover and obtain photometry for large numbers of supernovae; so many that it would be difficult to obtain a spectroscopic redshift for each. Using available supernova-analysis tools we find that there are several conditions in w...
متن کاملA Light Echo from Type Ia Supernova SN 1995E?
We identify a light echo candidate from Hubble Space Telescope (HST) imaging of NGC 2441, the host galaxy of the Type Ia supernova 1995E. From the echo’s angular size and the estimated distance to the host galaxy, we find a distance of 207±35 pc between the dust and the site of the supernova. If confirmed, this echo brings the total number of observed non-historical Type Ia light echoes to thre...
