论文摘要
我们将喷射驱动的双极核心塌陷超新星（CCSN）爆炸计算为双极杂质的爆炸（CSM），并表明赤道观察者发现光曲线具有快速，甚至突然落下。可能导致这种爆炸形态的场景是一种常见的包膜演化（CEE），在CCSN爆炸前不久，RSG祖细胞与更紧凑的伴侣相互作用，该伴侣在螺旋式上插入并插入核心。同伴可以是主要的序列星，中子星或黑洞。二元相互作用通过强烈的风将壳弹出，并且CEE在赤道平面中弹出了较密集的气体。我们假设同伴会产生质量并发射喷气机。我们进行了三维（3D）流体动力学模拟，在该模拟中，我们将弱喷气机（塑形喷嘴）发射到密集的壳中，并表明相互作用形成双极性CSM。由于迅速的爆发前芯旋转飞机驱动了CCSN爆炸。我们模拟了喷气机与双极CSM的相互作用，并使用简单的方案来计算光曲面。我们表明，观察者不太接近极性方向的灯光曲线的突然下降可以解释氢较差的发光超新星（LSN）SN 2018don的光弯曲。我们的研究增强了以下说法，即喷气驱动爆炸占了许多CCSNE的爆炸。
We calculate the lightcurves of jet-driven bipolar core collapse supernova (CCSN) explosions into a bipolar circumstellar mater (CSM) and show that an equatorial observer finds the lightcurves to possess a rapid, and even an abrupt, drop. The scenario that might lead to such an explosion morphology is a common envelope evolution (CEE) where shortly before the CCSN explosion the RSG progenitor interacts with a more compact companion that spirals-in and spins-up the core. The companion can be a main sequence star, a neutron star, or a black hole. The binary interaction ejects a shell through an intensive wind and the CEE ejects a denser gas in the equatorial plane. We assume that the companion accretes mass and launches jets. We conduct three-dimensional (3D) hydrodynamical simulations where we launch weak jets, the shaping jets, into the dense shell and show that the interaction forms a bipolar CSM. As a result of the rapid pre-collapse core rotation jets drive the CCSN explosion. We simulate the interaction of the jets with the bipolar CSM and use a simple scheme to calculate the lightcurves. We show that the abrupt drop in the lightcurve of an observer not too close to the polar directions can account for the lightcurve of the hydrogen poor luminous supernova (LSN) SN 2018don. Our study strengthens the claim that jet-driven explosions account for many, even most, CCSNe.
