A Comprehensive Analysis of Spitzer 4.5 μm Phase Curves of Hot Jupiters

The Astronomical Journal
Although exoplanetary science was not initially projected to be a substantial part of the Spitzer mission, its exoplanet observations set the stage for current and future surveys with JWST and Ariel.

Helium in the Extended Atmosphere of the Warm Superpuff TOI-1420b

The Astronomical Journal
Superpuffs are planets with exceptionally low densities ( ρ ≲ 0.1 g cm ^−3 ) and core masses ( M _c ≲ 5 M _⊕ ). Many lower-mass ( M _p ≲ 10 M _⊕ ) superpuffs are expected to be unstable to catastrophic mass loss via photoevaporation and/or boil-off ...

Early Accretion of Large Amounts of Solids for Directly Imaged Exoplanets

The Astrophysical Journal
As the number of planetary-mass objects (PMOs; ⪅13 M _Jupiter ) at wider separation (⪆10 au) grows, there is emerging evidence that they form differently from their higher-mass brown dwarf counterparts.

TOI-2005b: An Eccentric Warm Jupiter in Spin-orbit Alignment

The Astronomical Journal
We report the discovery and characterization of TOI-2005 b, a warm Jupiter on an eccentric ( e  ∼ 0.59), 17.3 days orbit around a V _mag = 9.867 rapidly rotating F-star.

A Complex Systems Approach to Exoplanet Atmospheric Chemistry: New Prospects for Ruling Out the Possibility of Alien Life As We Know It

The Planetary Science Journal
The near-term ability to characterize terrestrial exoplanet atmospheres may bring us closer to discovering alien life through atmospheric data. However, remotely detectable candidate biosignature gases are subject to false-positive signals because they ...

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

The Astrophysical Journal Letters
Though missions such as Kepler, K2, and TESS have discovered >2000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in ( P ≲ 3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be
