Stellar flares from the first TESS data release: exploring a new sample of M dwarfs
We perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence
during the first two months of the TESS mission. Flares may erode exoplanets' atmospheres …

Atmospheres of rocky exoplanets
R Wordsworth, L Kreidberg - Annual Review of Astronomy and …, 2022 - annualreviews.org
Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

Constraining the climate and ocean pH of the early Earth with a geological carbon cycle model
The early Earth's environment is controversial. Climatic estimates range from hot to glacial,
and inferred marine pH spans strongly alkaline to acidic. Better understanding of early …

Exoplanet biosignatures: understanding oxygen as a biosignature in the context of its environment
We describe how environmental context can help determine whether oxygen (O2) detected
in extrasolar planetary observations is more likely to have a biological source. Here we …

The pale orange dot: the spectrum and habitability of hazy Archean Earth
Recognizing whether a planet can support life is a primary goal of future exoplanet spectral
characterization missions, but past research on habitability assessment has largely ignored …

Impact of space weather on climate and habitability of terrestrial-type exoplanets
The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

Modeling repeated M dwarf flaring at an Earth-like planet in the habitable zone: atmospheric effects for an unmagnetized planet
Understanding the impact of active M dwarf stars on the atmospheric equilibrium and
surface conditions of a habitable zone Earth-like planet is key to assessing M dwarf planet …
