TOI-3664 b, TOI-4034 b & TOI-6564 b: Three new hot Jupiters around stars approaching the terminal age main sequence

Matthew P. Battley, Marina Lafarga, Edward Gillen +21

The paper reports the discovery and detailed characterization of three new hot Jupiters orbiting stars that are nearing the end of their main‑sequence lifetimes, providing data to…

Stellar Multiplicity of M Dwarfs with Short-period Giant Planets, and the Characterization of TOI-5628Ab

Tianjun Gan, Alexandrine L'Heureux, Charles Cadieux +33

Binary stars are ubiquitous, yet it remains unclear how wide-orbit stellar companions influence the formation of hot Jupiters, particularly around M dwarfs. Here, we first report t…

ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791

Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45

Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…

Shock wave formation in the thermosphere by an earthgrazing fireball: Empirical evidence for volatile-enhanced hydrodynamic shielding

Elizabeth A. Silber, Denis Vida, Miro Ronac Giannone +7

Hydrodynamic shielding is a theoretically well-established but observationally elusive and experimentally difficult-to-replicate phenomenon with implications that extend far beyond…

Impact of Clouds on the Atmosphere-Mantle Interface of Sub-Neptunes

Sagnick Mukherjee, Matthew C. Nixon, Luis Welbanks +4

Sub-Neptunes are among the most common type of close-in planets found in our galaxy, yet their bulk composition remains largely uncertain; H-rich envelopes overlaying rocky cores,…

Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System

Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47

Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…
