Origin of post-maximum bump in luminous Type Ic supernova 2019stc
نویسندگان
چکیده
We address the issue of postmaximum bump observed in light curve some superluminous supernovae. rule out popular mechanism a circumstellar interaction suggested for explanation. Instead we propose that is caused by magnetar dipole field enhancement several months after explosion. The modeling SN 2019stc based on thin shell approximation implies at age $\sim 90$ days initial magnetic should be amplified factor 2.8 to account bump. specific amplification newborn timescale has yet identified.

We present DES14X3taz, a new hydrogen-poor superluminous supernova (SLSN-I) discovered by the Dark Energy Survey (DES) supernova program, with additional photometric data provided by the Survey Using DECam for Superluminous Supernovae. Spectra obtained using Optical System for Imaging and low-IntermediateResolution Integrated Spectroscopy on the Gran Telescopio CANARIAS show DES14X3taz is an SL...
متن کاملSn2010ay Is a Luminous and Broad-lined Type Ic Supernova within a Low-metallicity Host Galaxy
We report on our serendipitous pre-discovery detection and detailed follow-up of the broad-lined Type Ic supernova SN 2010ay at z ≈ 0.067 imaged by the Pan-STARRS1 3π survey just ∼ 4 days after explosion. Combining our photometric observations with those available in the literature, we estimate the explosion date and the peak luminosity of the SN, MR ≈ −20.2 mag, significantly brighter than kno...
متن کاملThe Broad Line Type Ic Supernova Sn 2007ru: Adding to the Diversity of Type Ic Supernovae
Photometric and spectral evolution of the type Ic supernova SN 2007ru during the first 3 months are presented. The spectra show broad spectral features due to very high expansion velocity, normally seen in hypernovae. The photospheric velocity is higher than other type Ic supernovae. It is lower than SN 1998bw at ∼ 8 days after the explosion, but is comparable at later epochs. The light curve e...
متن کاملOptical follow-up observations of PTF10qts, a luminous broad-lined Type Ic supernova found by the Palomar Transient Factory
We present optical photometry and spectroscopy of the broad-lined Type Ic supernova (SN Ic-BL) PTF10qts, which was discovered as part of the Palomar Transient Factory. The supernova was located in a dwarf galaxy of magnitude r = 21.1 at a redshift z = 0.0907.We find that the R-band light curve is a poor proxy for bolometric data and use photometric and spectroscopic data to construct and constr...
متن کاملCarbon Monoxide in the Type Ic Supernova 2000ew
We present K -band (1.9 – 2.5 μm) spectra of the Type Ic SN 2000ew observed with IRCS on the Subaru Telescope. These data show the first detection of carbon monoxide (CO) emission in a Type Ic supernova. The detection of CO in SN 2000ew provides further evidence that molecule formation may be a common occurrence in core-collapse supernova ejecta. The spectrum also contains narrow emission lines...
