Sn 2005kd: Another Very Luminous, Slowly Declining Type Iin Supernova
نویسنده
چکیده
CCD U BV RI photometry is presented for type IIn SN 2005kd. The maximum luminosity exceeded MV = −19.8, and SN remained brighter than −18 mag for about 400 days. While overall photometric evolution is quite similar to SN 1997cy, SN 2005kd shows a plateau at phases between 119 and 311 days past explosion, which is a unique feature for SN IIn.

Discovery of the Extremely Energetic Supernova 2008fz
We report the discovery and initial observations of the energetic type-IIn supernova (SN), 2008fz possibly the most energetic SN ever discovered. This event, like the similarly luminous type-IIn SN 2006gy, exhibits a smooth very slowly evolving light curve. As is characteristic of type-IIn SN, the early spectra of 2008fz initially exhibited narrow Balmer lines which were replaced by a broader c...
متن کاملThe Properties of Hypernovae : SNe Ic 1998 bw , 1997 ef
We discuss the properties of the hyper-energetic Type Ic supernovae (SNe Ic) 1998bw and 1997ef and Type IIn supernova (SN IIn) 1997cy. SNe Ic 1998bw and 1997ef are characterized by their large luminosity and the very broad spectral features. Their observed properties can be explained if they are very energetic SN explosions with the kinetic energy of EK ∼ > 1 × 10 52 erg, originating probably f...
متن کاملEvidence of Asymmetry in SN 2007 rt , a Type IIn Supernova
An optical photometric and spectroscopic analysis of the slowly-evolving Type IIn SN 2007rt is presented, covering a duration of 481 days after discovery. Its earliest spectrum, taken 102 days after the explosion epoch, indicates the presence of a dense circumstellar medium, with which the supernova ejecta is interacting. This is supported by the slowly-evolving light curve that declines at a r...
متن کاملThe Rise of the Remarkable Type IIn Supernova SN 2009ip
Recent observations by Mauerhan et al. have shown the unprecedented transition of the previously identified luminous blue variable (LBV) and supernova impostor SN 2009ip to a real Type IIn supernova (SN) explosion. We present high-cadence optical imaging of SN 2009ip obtained between 2012 UT Sep. 23.6 and Oct. 9.6, using 0.3 − 0.4 meter aperture telescopes from the Coral Towers Observatory in C...
