Target RA (J2000): 26.632746 and deg Target Dec (J2000): 2.70057 and deg Gaia GMag: 9.395 Programme ID: CH_PR140061 Programme Manager: LENDL PI of observing programme: Benz Title of programme: Axis 2 - A Deep search for hot JupIter VAriability (DIVA) Abstract: The temporal stability of hot Jupiter atmospheres remains an open question. While there are several tentative detections of changes in the observed planetary occultation depths phase curve shapes or transmission spectra no indisputable evidence exists to date. This program will perform a deep search for variability in the dayside brightness of several hot Jupiters. A detection of clear variability and the measurement of its timescale would open the door to a suite of follow-up studies involving the dynamical behaviour of exoplanet atmospheres. [truncated!

项目标题：Axis 2 - 热木星变异性深度搜索（DIVA）
摘要：热木星大气的时间稳定性仍是一个悬而未决的问题。尽管已有若干关于观测到的行星掩星深度、相位曲线形状或透射光谱变化的初步探测结果，但迄今为止尚无确凿证据。本项目将对若干热木星的昼侧亮度变异性展开深度搜索。若能明确探测到变异性并测量其时间尺度，将为一系列涉及系外行星大气动力学行为的后续研究打开大门。
