论文摘要
我们将喷射动力的ILOT方案应用于两个最近研究的中间光度光瞬变（ILOTS），并找到相关的壳体质量和喷气机的能量，这些能量可能解释了这些卵子的爆发。在喷射动力的ILOT场景中，围绕二进制系统的一颗恒星发射喷气机。喷气机与先前弹出的慢壳的相互作用将动能转化为热能，其中一部分被辐射出来。我们应用了两种模型的喷射动力ILOT方案。在球形外壳模型中，喷气机加速了球形外壳，而在茧玩具模型中，喷气机渗透到壳中并充气热气泡，茧。我们发现一致的结果。对于ILOT（ILRT：中间光度红色瞬变）Snhunt120，我们发现壳体质量和喷气机的能量分别为MS = 0.5-1MO和E2J = 5E47erg。喷气机的半开角为alpha = 30-60度。对于ILOT的第二个峰（发光红色Nova）AT2014EJ，我们发现这些数量为MS = 1-2MO，E2J = 1.5E48erg，alpha = 20-30度。这些模型无法判断这些卵子是由留下一颗恒星的出色合并提供动力的，还是由两颗恒星存活的质传。在这两种情况下，喷气机的壳体和能量的质量都表明二进制祖细胞系统是巨大的，合并质量为M1+M2> 10MO。
We apply the jet-powered ILOT scenario to two recently studied intermediate luminosity optical transients (ILOTs), and find the relevant shell mass and jets' energy that might account for the outbursts of these ILOTs. In the jet-powered ILOT scenario accretion disk around one of the stars of a binary system launches jets. The interaction of the jets with a previously ejected slow shell converts kinetic energy to thermal energy, part of which is radiated away. We apply two models of the jet-powered ILOT scenario. In the spherical shell model the jets accelerate a spherical shell, while in the cocoon toy model the jets penetrate into the shell and inflate hot bubbles, the cocoons. We find consistent results. For the ILOT (ILRT: intermediate luminosity red transient) SNhunt120 we find the shell mass and jets' energy to be Ms=0.5-1Mo and E2j=5e47erg, respectively. The jets' half opening angle is alpha=30-60 degrees. For the second peak of the ILOT (luminous red nova) AT2014ej we find these quantities to be Ms=1-2Mo and E2j=1.5e48erg, with alpha=20-30 degrees. The models cannot tell whether these ILOTs were powered by a stellar merger that leaves one star, or by mass transfer where both stars survived. In both cases the masses of the shells and energies of the jets suggest that the binary progenitor system was massive, with a combined mass of M1+M2>10Mo.
