Lessons from Hubble and Spitzer: 1D Self-consistent Model Grids for 19 Hot Jupiter Emission Spectra

The Astrophysical Journal
We present a population-level analysis of the dayside thermal emission spectra of 19 planets observed with Hubble WFC3 and Spitzer IRAC 3.6 and 4.5 μ m, spanning equilibrium temperatures 1200–2700 K and 0.7–10.5 Jupiter masses.

Earth as an Exoplanet. III. Using Empirical Thermal Emission Spectra as an Input for Atmospheric Retrieval of an Earth-twin Exoplanet

The Astrophysical Journal
In this study, we treat Earth as an exoplanet and investigate our home planet by means of a potential future mid-infrared space mission called the Large Interferometer For Exoplanets (LIFE).

X-Ray and UV Observations of the Young Sun HIP 67522: Evidence of Lyα Absorption within the Planetary System

The Astronomical Journal
We present ultraviolet (UV) spectroscopy of the 17 Myr, G0V star HIP 67522. The UV spectrum is characterized by strong chromospheric and transition region emission lines.

Characterizing the Time Variability of 2M1207 A + b with JWST NIRSpec/PRISM

The Astronomical Journal
We present JWST NIRSpec/PRISM integral field unit time-resolved observations of 2M1207 A and b (TWA 27), an ∼10 Myr binary system consisting of an ∼2500 K substellar primary hosting an ∼1300 K companion.

Lyα Emission from K and M Dwarfs: Intrinsic Profiles, Variability, and Flux in the Habitable Zone

The Astrophysical Journal
Lyman-alpha (Ly α ) is the most prominent ultraviolet (UV) emission line in low-mass stars, playing a crucial role in exoplanet atmospheric photochemistry, heating, and escape.
