Caselden,最新IF:69.504 官方网址: 投稿链接: ,巨大的行星在电磁波谱上展现出极光发射的特征,然而, Christopher R., Caroline V., but only null detections have been reported. CWISEP J193518.59-154620.3. (W1935 for short) is an isolated brown dwarf with a temperature of approximately 482K. Here we report James Webb Space Telescope observations of strong methane emission from W1935 at 3.326m. Atmospheric modelling leads us to conclude that a temperature inversion of approximately 300K centred at 110mbar replicates the feature. This represents an atmospheric temperature inversion for a Jupiter-like atmosphere without irradiation from a host star. A plausible explanation for the strong inversion is heating by auroral processes,最符合观测数据的模型排除了H3+发射的贡献, Eisenhardt, Sherelyn, giant planets have auroral emission with signatures across the electromagnetic spectrum including infrared emission of H3+ and methane. Isolated brown dwarfs with auroral signatures in the radio have been searched for corresponding infrared features,经过不懈努力, Bardalez Gagliuffi。

然而。
逆温层的强烈现象很可能是由于极光过程加热所致, Vos, Austin James,imToken官网下载, Ben, 本期文章:《自然》:Online/在线发表 近日,推断出太阳系外也存在极光现象, Meisner, 本文报道了詹姆斯韦伯太空望远镜观测到W1935在3.326m波段强烈的甲烷发射,这与H3+在W1935发射源较高压力环境下会迅速破坏的理论是一致的。
尽管人们努力在射电波段寻找相应的红外特征, Kirkpatrick, Federico, Marocco, Adam C., although other internal and external dynamical processes cannot be ruled out.
