An Obliquity Measurement of the Hot Neptune TOI-1694b

The Astronomical Journal
We present spectral observations of the multiplanet host TOI-1694 during the transit of TOI-1694b, a 26.1 M _⊕ hot Neptune with a 3.77 day orbit. By analyzing radial velocities obtained from the Keck Planet Finder, we modeled the Rossiter–McLaughlin ...

A Larger Sample Confirms Small Planets around Hot Stars Are Misaligned

The Astrophysical Journal Letters
The distribution of stellar obliquities provides critical insight into the formation and evolution pathways of exoplanets. In the past decade, it was found that hot stars hosting hot Jupiters are more likely to have high obliquities than cool stars, but ...

Eclipse Mapping with MIRI: 2D Map of HD 189733b from 8 μm JWST MIRI LRS Observations

The Astrophysical Journal Letters
Observations and models of transiting hot Jupiter exoplanets indicate that atmospheric circulation features may cause large spatial flux contrasts across their daysides.

Formation of Near-surface Atmospheric Inversion and Surface Inversion in Hothouse Climates

The Astrophysical Journal
A hothouse climate may develop throughout Earth’s history and its warming future, and on potentially habitable exoplanets near the inner edge of the habitable zone.
