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

Studying the evolution of hot Jupiters requires a sample of well-characterised systems across all evolutionary states. We present three new gas giant exoplanets around stars approa…

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…

Europa's Lyman- emissions from HST/STIS observations

L. Roth, K. D. Retherford, J. Saur +13

An image of Lyman- (Ly) emission from Europa obtained with the Hubble Space Telescope Space Telescope Imaging Spectrograph (HST/STIS) has previously provided the first eviden…

Asteroid modelling by starlight diffraction: The shape of Dimorphos, the satellite of (65803) Didymos

P. Tanga, K. Tsiganis, D. Souami +17

The DART spacecraft impacted Dimorphos, the satellite of (65803) Didymos, in September 2022. Evidence of crater formation and possible global reshaping has been obtained indirectly…

Multi-Sensor Trajectory Reconstruction of the 24 April 2025 Alaska Fireball and Implications for Planetary Defense

L. T. Scamfer, E. A. Silber, M. D. Fries +6

On 24 April 2025 at 18:30:57 UTC, a bright daytime fireball over Southcentral Alaska was detected by 37 seismic stations, 16 single infrasound sensors, and four infrasound arrays,…

TOI-4552 b: A new ultra-short period rocky world revealed by NIRPS and TESS

Avidaan Srivastava, René Doyon, François Bouchy +57

A particularly intriguing subclass of rocky exoplanets are the ultra-short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly rare a…

The shape and spin state of (275677) 2000 RS11 from ground-based radar and optical observations

Richard E. Cannon, Agata Rożek, Kaley Brauer +12

Near-Earth asteroid (275677) 2000 RS11 was observed over 5 days in March 2014 with both the Arecibo (2380 MHz, 12.6 cm) and Goldstone (8560 MHz, 3.5 cm) planetary radar systems. Th…

PICASO 4.0: Clouds and Photochemistry in Climate Models of Brown Dwarfs and Exoplanets

James Mang, Natasha E. Batalha, Caroline V. Morley +8

We present a major update to the open-source atmospheric modeling package \texttt{PICASO}, designed for simulating the thermal structure and spectra of hydrogen-rich atmospheres of…

NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period

Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148

We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission

J. Milli, J. Olofsson, M. Bonduelle +33

Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…

Structure of Jupiter's High-Latitude Storms: Folded Filamentary Regions Revealed by Juno

L. N. Fletcher, Z. Zhang, S. Brown +17

Sprawling, turbulent cloud formations dominate the meteorology of Jupiter's mid-to-high latitudes, known as Folded Filamentary Regions (FFRs). A multi-wavelength characterisation b…
