JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e

Astrophysical Journal Letters
The TRAPPIST-1 system offers one of the best opportunities to characterize temperate terrestrial planets beyond our own solar system. Within the TRAPPIST-1 system, planet e stands out as highly likely to sustain surface liquid water if it possesses an ...

Diversity of Low-mass Planet Atmospheres in the C–H–O–N–S–Cl System with Interior Dissolution, Nonideality, and Condensation: Application to TRAPPIST-1e and Sub-Neptunes

Astrophysical Journal
A quantitative understanding of the nature and composition of low-mass rocky (exo)planet atmospheres during their evolution is needed to interpret observations.

Tracing the inner edge of the habitable zone with sulfur chemistry

Science Advances
The circumstellar liquid-water habitable zone guides our search for potentially inhabited exoplanets but remains observationally untested. We show that the inner edge of the habitable zone can now be mapped among exoplanets using their lack of surface ...

The hidden subtlety of beer foam stability: A blueprint for advanced foam formulations

The Physics of Fluids
It is believed that the structure and properties of protein-rich layers influence beer foam stability through their impact on both surface tension and surface viscosity.

Networking in Interstellar Dimensions: Communicating With TRAPPIST-1

IEEE Transactions on Aerospace and Electronic Systems, 2019
The recent discovery of potentially habitable planets orbiting the TRAPPIST-1 system intensified interest in interstellar exploration. In these challenging mission concepts, communication protocols would need to cope with unprecedented signal propagation delays.

Estimation of the tidal heating in the TRAPPIST-1 planets. Influence of the internal structure

Astronomy & Astrophysics
With the arrival of JWST observations of the TRAPPIST-1 planets—particularly secondary transit depths and phase curves—it is timely to reassess the contribution of tidal heating to their heat budget.

Uncertainties in the Inference of Internal Structure: The Case of TRAPPIST-1 f

Astrophysical Journal
We use the TRAPPIST-1 system as a model observation of Earth-like planets. The densities of these planets being 1%–10% less than the Earth suggest that the outer planets may host significant hydrospheres. We explore the uncertainty in water mass fraction

Uniform Reanalysis of JWST MIRI 15 μm Exoplanet Eclipse Observations Using Frame-normalized Principal Component Analysis

Astrophysical Journal Letters
James Webb Space Telescope (JWST) MIRI 15 μm time-series eclipse photometry presents a powerful way to probe for the presence of atmospheres on low-temperature rocky exoplanets orbiting nearby stars. Here, we introduce a novel technique, frame-normalized

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths

Astronomical Journal
Space weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...
