与平流层红外天文观测台(SOFIA)进行系外行星研究

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)

Daniel Angerhausen

摘要:

当平流层红外天文观测台(SOFIA)的构想和第一个科学案例的定义,系外行星还没有被发现。然而,后来的研究表明,在行星凌日和日食期间,利用索非亚研究所的仪器,特别是HIPO-FLITECAM和FPI+光学和近红外仪器,进行光学和近红外测光和分光光度跟踪观测是可行的。此外,与这一研究领域的其他地面和空间观测站相比,SOFIA空基平台具有许多独特的优势。在这里,我们将概述这些理论优势,介绍一些科学案例和SOFIA前五个观测周期的两个观测结果--用HIPO观测热木星HD 189733 b,用FLIPO和FPI+观测超级地球GJ 1214 b。基于这些早期的产品可用于这个科学案例,我们评估SOFIA的潜力和未来的前景在平流层的光学和红外系外行星分光光度计领域。

英文摘要:

When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and eclipses are feasible with SOFIA's instrumentation, in particular with the HIPO-FLITECAM and FPI+ optical and near infrared (NIR) instruments. Additionally, the airborne-based platform SOFIA has a number of unique advantages when compared to other ground- and space-based observatories in this field of research. Here we will outline these theoretical advantages, present some sample science cases and the results of two observations from SOFIA's first five observation cycles -- an observation of the Hot Jupiter HD 189733b with HIPO and an observation of the Super-Earth GJ 1214b with FLIPO and FPI+. Based on these early products available to this science case, we evaluate SOFIA's potential and future perspectives in the field of optical and infrared exoplanet spectrophotometry in the stratosphere.
