SPECTROPOLARIMETRY OF EXTREMELY LUMINOUS TYPE Ia SUPERNOVA 2009dc: NEARLY SPHERICAL EXPLOSION OF SUPER-CHANDRASEKHAR MASS WHITE DWARF
We present the first spectropolarimetric observations of a candidate of super-Chandrasekhar mass Type Ia supernova (SN): SN 2009dc. The observations were performed at 5.6 and 89.5 days after the B-band maximum. The data taken at the later epoch are used to determine the interstellar polarization. Continuum polarization is found to be small (< 0.3%), indicating that the explosion is nearly spher...
متن کاملTHE EXTREMELY LUMINOUS SUPERNOVA 2006gy AT LATE PHASE: DETECTION OF OPTICAL EMISSION FROM SUPERNOVA
Supernova (SN) 2006gy is an extremely luminous Type IIn SN characterized by the bright peak magnitude MR ∼ −22 mag and its long duration. The mechanism giving rise to its huge luminosity is still unclear. We performed optical spectroscopy and photometry of SN 2006gy at late time, ∼ 400 days after the explosion, with the Subaru/FOCAS in a good seeing condition. We carefully extracted the SN comp...
متن کاملConstraints on holographic dark energy from Type Ia supernova observations
In this paper, we use the Type Ia supernovae data to constrain the holographic dark energy model proposed by Li. We also apply a cosmic age test to this analysis. We consider in this paper a spatially flat FRW universe with matter component and holographic dark energy component. The fit result shows that the case c < 1 is favored, which implies that the holographic dark energy behaves as a quin...
متن کاملType Ia supernova SN 2003 du : optical observations
U BV RI photometry and optical spectra of type Ia supernova SN 2003du obtained at the Indian Astronomical Observatory for nearly a year since discovery are presented. The apparent magnitude at maximum was B = 13.53 ± 0.02 mag, and the colour (B − V) = −0.08 ± 0.03 mag. The luminosity decline rate, ∆m15(B) = 1.04 ± 0.04 mag indicates an absolute B magnitude at maximum of M max B = −19.34 ± 0.3 m...
متن کاملThe Type Ia Supernova
We present the rst measurement of the rate of Type Ia super-novae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as described in more detail at this meeting by Perlmutter et al. (1996). We present our methods for estimating the numbers of galaxies and the number of solar luminosities to which the survey is sensitive, the supernova detec...
