With more than 1000 hours of observation from Feb 2016 to Oct 2019, the Spitzer Exploration Program Red Worlds (ID: 13067, 13175 and 14223) exclusively targeted TRAPPIST-1, a nearby (12pc) ultracool dwarf star orbited by seven transiting Earth-sized planets, all well-suited for a detailed atmospheric characterization with the upcoming JWST. In this paper, we present the global results of the project. We analyzed 88 new transits and combined them with 100 previously analyzed transits, for a…

Improved Constraints for the XUV Luminosity Evolution of Trappist-1
We re-examine the XUV luminosity evolution of TRAPPIST-1 utilizing new observational constraints (XUV and bolometric luminosity) from multi-epoch X-ray/UV photometry. Following the formalism
A Review of Possible Planetary Atmospheres in the TRAPPIST-1 System
TLDR
It is shown that (i) Hubble Space Telescope transit observations, (ii) bulk density measurements comparison with H2-rich planets mass-radius relationships, (iii) atmospheric escape modelling, and (iv) gas accretion modelling altogether offer solid evidence against the presence of hydrogen-dominated—cloud-free and cloudy—atmospheres around TRAPPIST-1 planets.
Refining the Transit-timing and Photometric Analysis of TRAPPIST-1: Masses, Radii, Densities, Dynamics, and Ephemerides
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N-body
Timescales for Prebiotic Photochemistry Under Realistic Surface Ultraviolet Conditions
TLDR
Investigation of whether the UV flux available on the surface of early Earth, given a favorable atmosphere, can facilitate a variety of prebiotic chemical syntheses suggests the plausibility of the photoproduction of purine deoxyribonucleotides, which proceeds more efficiently in the presence of bisulfite.
An upper limit on late accretion and water delivery in the TRAPPIST-1 exoplanet system
The TRAPPIST-1 system contains seven roughly Earth-sized planets locked in a multiresonant orbital configuration 1 , 2 , which has enabled precise measurements of the planets’ masses and constrained
Characterisation of the hydrospheres of TRAPPIST-1 planets
Planetary mass and radius data are showing a wide variety in densities of low-mass exoplanets. This includes sub-Neptunes, whose low densities can be explained with the presence of a volatile-rich
Confirmation of a Dynamical Model for the TRAPPIST-1 Exoplanetary System
We present a new transit of TRAPPIST-1 d from 2021 August 25. The measured mid-point of this transit agrees with the prediction from a recently published dynamical model for the TRAPPIST-1 system and
