Towards Doppler eclipse mapping of hot Jupiters

Astronomy & Astrophysics
Context. In the last decade, ground-based high-resolution spectroscopy (HRS) has emerged as a powerful method to probe exoplanet atmospheres both in transit and thermal emission.

Exploring Warm Jupiter Migration Pathways with Eccentricities. II. Correlations with Host Star Properties and Orbital Separation

The Astronomical Journal
Warm Jupiters with orbital periods of ≈10–365 days represent a population of giant planets located well within the water ice line but beyond the region of tidal influence of their host star relevant for high-eccentricity tidal migration.

The Nitrogen Chemistry in Hot Jupiters Atmosphere

, 2011
International audienceThe atmosphere of hot Jupiters can be probed by primary transit and secondary eclipse spectroscopy. In order to constrain the atmospheric thermal structure and composition from observables, chemical models are necessary.

Exoplanet Ephemerides Change Observations (ExoEcho). I. Transit Timing Analysis of 37 Exoplanets Using HST/WFC3 Data

The Astronomical Journal
The ExoEcho project is designed to study the photodynamics of exoplanets by leveraging high-precision transit timing data from ground- and space-based telescopes.

Stability of Multiplanet Systems through Hot Jupiter Destruction

The Astrophysical Journal Letters
Recent observational and theoretical work suggests that the sub-Jovian desert (periods ≲3 days, masses ∼10–100 M _⊕ ) hosts the remains of destroyed hot Jupiters (“desert dwellers”).

“Popcorn Planets” Are Not Actively Inflated by Eccentricity Tides

The Astrophysical Journal Letters
Recent discoveries have revealed a population of “popcorn planets” that have masses similar to that of Neptune but radii comparable to Jupiter, leading to exceptionally low bulk densities ρ _p  ≲ 0.3 g cm ^−3 .
