Impact of variable photospheric radius on exoplanet atmospheric retrievals
Monthly Notices of the Royal Astronomical Society: Letters, 2022 ABSTRACT Inverse techniques are used to extract information about an exoplanet’s atmosphere. These techniques are prone to biased results if the appropriate forward model is not used. One assumption used in a forward model is to assume that the radius of the planet is constant with wavelength; however, a more realistic assumption is that

Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

Evolutionary and functional relationships between plant and microbial C<sub>1</sub> metabolism in terrestrial ecosystems. [PDF]
New PhytolSummary One‐carbon (C1) metabolism, centered on the universal methyl donor S‐adenosyl methionine (SAM), plays critical roles in biosynthesis, redox regulation, and stress responses across plants and microbes. A recently proposed photosynthetic C1 pathway links SAM methyl groups directly to RuBisCO‐mediated CO2 assimilation and integrates with nitrogen ...

Magnetohydrodynamical Torsional Oscillations from Thermoresistive Instability in Hot Jupiters
The Astrophysical Journal, 2023 Hot Jupiter atmospheres may be subject to a thermoresistive instability where an increase in the electrical conductivity due to ohmic heating results in runaway of the atmospheric temperature.

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]
, 2012 The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...
