Description

Supplementary material for 'High Tide or Riptide on the Cosmic Shoreline? A Water-rich Atmosphere or Stellar Contamination for the Warm Super-Earth GJ 486b from JWST Observations' by Moran & Stevenson et al., ApJL (2023).

This repository contains four categories of data products:

  1. White light curves — White light curves produced for Visit 1 and 2, for detectors NRS1 and NRS2 via the FIREFLy pipeline and the open-source codes Eureka! and Tiberius
  2. Transmission spectra — Reduced transmission spectra from three data reduction codes (Eureka!, FIREFLy, and Tiberius) for both G395H visits.
  3. Stellar spectra and models — Flux calibrated observed stellar spectra of GJ 486 from each G395H visit, along with best-fit PHOENIX stellar models.
  4. Atmospheric models — Atmospheric forward models used to interpret the data, produced from the open source PICASO and CHIMERA codes.
