Abstract

The Ariel mission will execute an ambitious survey to measure transit and / or secondary eclipse spectra of the atmospheres of about 1000 exoplanets. I outline here some possible scientific applications of the exquisite Ariel Core Survey data, beyond the science for which they are primarily designed.

Highlights

  • Along with thermal IR spectroscopy, Ariel will produce exquisite optical and nearIR photometric data, with multi-band photometry at 1 Hz sampling

  • A very short summary of some of these potential extended use applications of the Ariel Core Survey data is included in Tinetti et al [49]; further examples and more detailed discussions can be found in Szabó et al [46], Borsato et al [7], and Garai (2020)

  • This paper extends the work of Szabó et al [46], Borsato et al [7], and Garai [18] and focusses on some straightforward applications to stellar astrophysics along with some more speculative potential applications

Summary

Introduction

Along with thermal IR spectroscopy, Ariel will produce exquisite optical and nearIR photometric data, with multi-band photometry at 1 Hz sampling. With photometric data of this quality, Ariel is sensitive to the intrinsic variability of even very quiet stars. This short paper outlines a variety of science which might be executed with the ground-breaking data included in Ariel’s Core Survey. A very short summary of some of these potential extended use applications of the Ariel Core Survey data is included in Tinetti et al [49]; further examples and more detailed discussions can be found in Szabó et al [46], Borsato et al [7], and Garai (2020).
