TrExoLiSTS: Transiting Exoplanets List of Space Telescope Spectroscopy

TL;DR

TrExoLiSTS is a web resource that catalogs and provides access to existing space telescope observations of transiting exoplanet atmospheres, aiding research and proposal planning.

Contribution

It introduces a comprehensive online database for exoplanet atmosphere observations from HST and JWST, streamlining data access and reducing redundant efforts.

Findings

Includes observations from HST WFC3 in various modes

Provides reference data for visit quality and observation details

Plans to expand to other instruments and JWST data

Abstract

We present the STScI WFC3 project webpage, Transiting Exoplanets List of Space Telescope Spectroscopy, TrExoLiSTS. It tabulates existing observations of transiting exoplanet atmospheres, available in the MAST archive made with HST WFC3 using the stare or spatial scan mode. A parallel page is available for all instruments aboard JWST using the spectral Time Series Observation (TSO) mode. The web pages include observations obtained during primary transits, secondary eclipses and phase curves. TREXOLISTS facilitates proposal preparation for programs that are highly-complementary to existing programs in terms of targets, wavelength coverage, as well as reduces duplication and redundant effort. Reference for the quality of the HST WFC3 visits taken more than 1.5 years ago are made available via including diagrams of the direct image, white light curve and drift of the spectral time series across the detector. Future improvements to the webpage will include: Expanding program query to other HST instruments and reference for the quality of JWST visits.
