We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first ∼100 days from explosion. Based on the light curve morphology, we find that SN 2019cad resembles the double-peaked type Ib/c SN 2005bf and the type Ic PTF11mnb. Unlike those two objects, SN 2019cad also shows the initial peak in the redder bands. Inspection of the g-band light curve indicates the initial peak is reached in ∼8 days, while the r band peak occurred ∼15 days post-explosion. A second and more prominent peak is reached in all bands at ∼45 days past explosion, followed by and fast decline from ∼60 days. During the first 30 days, the spectra of SN 2019cad show the typical features of a type Ic SN, however, after 40 days, a blue continuum with prominent lines of Si II 6355 and C II 6580 is observed again. Comparing the bolometric light curve to hydrodynamical models, we find that SN 2019cad is consistent with a pre-SN mass of 11 M⊙, and an explosion energy of 3.5 foe. The light curve morphology can be reproduced either by a double-peaked 56Ni distribution with an external component of 0.041 M⊙ and an internal component of 0.3 M⊙ or a double-peaked 56Ni distribution plus magnetar model (P ∼11 ms and B ∼26E14 G). If SN 2019cad were to suffer from significant host reddening (which cannot be ruled out), the 56Ni model would require extreme values, while the magnetar model would still be feasible.
Presentamos la evolución fotométrica y espectroscópica de la supernova (SN) 2019cad durante los primeros ∼100 días desde la explosión. Con base en la morfología de la curva de luz, encontramos que SN 2019cad se asemeja al tipo Ib / c SN 2005bf de doble pico y al tipo Ic PTF11mnb. A diferencia de esos dos objetos, SN 2019cad también muestra el pico inicial en las bandas más rojas. La inspección de la curva de luz de la banda g indica que el pico inicial se alcanza en ~ 8 días, mientras que el pico de la banda r ocurrió ~ 15 días después de la explosión. Se alcanza un segundo pico más prominente en todas las bandas a los 45 días después de la explosión, seguido de un rápido descenso desde los 60 días. Durante los primeros 30 días, los espectros de SN 2019cad muestran las características típicas de un SN tipo Ic, sin embargo, después de 40 días, se observa nuevamente un continuo azul con líneas prominentes de Si II 6355 y C II 6580. Al comparar la curva de luz bolométrica con los modelos hidrodinámicos, encontramos que SN 2019cad es consistente con una masa pre-SN de 11 M⊙ y una energía de explosión de 3,5 enemigos. La morfología de la curva de luz se puede reproducir mediante una distribución de 56Ni de doble pico con un componente externo de 0,041 M⊙ y un componente interno de 0,3 M⊙ o una distribución de 56Ni de doble pico más modelo de magnetar (P ∼11 ms y B ∼26E14 GRAMO). Si SN 2019cad sufriera un enrojecimiento significativo del anfitrión (que no se puede descartar), el modelo 56Ni requeriría valores extremos, mientras que el modelo magnetar aún sería factible. - Materia

We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first ∼100 days from explosion. Based on the light curve morphology, we find that SN 2019cad resembles the double-peaked type Ib/c SN 2005bf and the type Ic PTF11mnb. Unlike those two objects, SN 2019cad also shows the initial peak in the redder bands. Inspection of the g-band light curve indicates the initial peak is reached in ∼8 days, while the r band peak occurred ∼15 days post-explosion. A second and more prominent peak is reached in all bands at ∼45 days past explosion, followed by and fast decline from ∼60 days. During the first 30 days, the spectra of SN 2019cad show the typical features of a type Ic SN, however, after 40 days, a blue continuum with prominent lines of Si II 6355 and C II 6580 is observed again. Comparing the bolometric light curve to hydrodynamical models, we find that SN 2019cad is consistent with a pre-SN mass of 11 M⊙, and an explosion energy of 3.5 foe. The light curve morphology can be reproduced either by a double-peaked 56Ni distribution with an external component of 0.041 M⊙ and an internal component of 0.3 M⊙ or a double-peaked 56Ni distribution plus magnetar model (P ∼11 ms and B ∼26E14 G). If SN 2019cad were to suffer from significant host reddening (which cannot be ruled out), the 56Ni model would require extreme values, while the magnetar model would still be feasible. Presentamos la evolución fotométrica y espectroscópica de la supernova (SN) 2019cad durante los primeros ∼100 días desde la explosión. Con base en la morfología de la curva de luz, encontramos que SN 2019cad se asemeja al tipo Ib / c SN 2005bf de doble pico y al tipo Ic PTF11mnb. A diferencia de esos dos objetos, SN 2019cad también muestra el pico inicial en las bandas más rojas. La inspección de la curva de luz de la banda g indica que el pico inicial se alcanza en ~ 8 días, mientras que el pico de la banda r ocurrió ~ 15 días después de la explosión. Se alcanza un segundo pico más prominente en todas las bandas a los 45 días después de la explosión, seguido de un rápido descenso desde los 60 días. Durante los primeros 30 días, los espectros de SN 2019cad muestran las características típicas de un SN tipo Ic, sin embargo, después de 40 días, se observa nuevamente un continuo azul con líneas prominentes de Si II 6355 y C II 6580. Al comparar la curva de luz bolométrica con los modelos hidrodinámicos, encontramos que SN 2019cad es consistente con una masa pre-SN de 11 M⊙ y una energía de explosión de 3,5 enemigos. La morfología de la curva de luz se puede reproducir mediante una distribución de 56Ni de doble pico con un componente externo de 0,041 M⊙ y un componente interno de 0,3 M⊙ o una distribución de 56Ni de doble pico más modelo de magnetar (P ∼11 ms y B ∼26E14 GRAMO). Si SN 2019cad sufriera un enrojecimiento significativo del anfitrión (que no se puede descartar), el modelo 56Ni requeriría valores extremos, mientras que el modelo magnetar aún sería factible. |
