abstract
A new hot line list for the main isotopologue of CO$_2$ is presented. The line list consists of almost 2.5 billion transitions between 3.5 million rotation-vibration states of CO$_2$ in its ground electronic state, covering the wavenumber range 0-20000 cm$^{-1}$ ($\lambda >0.5$ $\mu$m) with the upper and lower energy thresholds of 36 000 cm$^{-1}$ and 16 000 cm$^{-1}$, respectively. The ro-vibrational energies and wavefunctions are computed variationally using the Ames-2 accurate empirical potential energy surface. The ro-vibrational transition probabilities in the form of Einstein coefficients are computed using an accurate ab initio dipole moment surface using variational program TROVE. A new implementation of TROVE which uses an exact nuclear-motion kinetic energy operator is employed. Comparisons with the existing hot line lists are presented. The line list should be useful for atmospheric retrievals of exoplanets and cool stars. The UCL-4000 line list is available from the CDS and ExoMol databases.

Recurrent stellar flares produce both short-term and cumulative changes in the atmospheric composition and transmission spectrum of a metal-rich hot Jupiter, with water and methane showing declining trends over decades.
JWST MIRI transmission spectrum of the warm Neptune HD 106315 c reveals abundant water and tentative ammonia, with no detection of sulfur-bearing species despite strong stellar UV irradiation.
Pyrat Bay 2.0 adds equilibrium chemistry, radiative equilibrium, and vertically varying abundance retrieval, and simulations indicate JWST-quality spectra can recover such variations.
A 3D temperature parameterization derived from energy-balance timescales, fit to JWST phase-curve spectra of WASP-121b, recovers a day–night asymmetric atmosphere with a nightside methane enhancement and hints of magnetic drag.
LIFE baseline mid-IR observations of Earth-sized planets at 10 pc can retrieve CO2, CH4, and NH3 well enough to distinguish mantle redox states from IW-6 to IW+6 under the paper's modeling assumptions.
JWST retrievals of two mid-L benchmark brown dwarfs infer C/O around 0.70, cloud compositions consistent with phase equilibrium for one object and challenging it for the other.
A quench-pressure parameterisation with two free parameters recovers unbiased C/O and [M/H] from synthetic JWST spectra with vertical mixing, and tentatively detects quenching and photochemical H2S depletion in HD 189733b NIRCam data.
