An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results
An HST survey maps the Galactic Bulge, creating a high-resolution legacy dataset and aiding future Roman exoplanet characterization.
A preliminary exploration of the effects of baseline length for the LIFE space mission
This paper explores baseline lengths for the LIFE space mission, finding that shorter ranges (e.g., 25-80m) are feasible with minimal performance loss.
Jovian Zonal Winds Revealed from Cassini/VIMS Observations
New correlation-based method uses Cassini/VIMS data to map Jupiter's zonal winds and their vertical structure, revealing weaker shear than previously thought.
Resonant Hamiltonian Dynamics in the CR3BP: Bistability and Stochastic Resonance in Binary Planetary Systems
A new Hamiltonian framework unifies resonant dynamics in binary planetary systems, predicting bistability and stochastic resonance.
A single power law for the TRAPPIST-1 flare distribution across four orders of magnitude in energy
Researchers found a single power law describes TRAPPIST-1's flare frequency distribution over four orders of magnitude in energy.
Finding Alien Worlds in Queensland -- A Decade of MINERVA-Australis
MINERVA-Australis, a dedicated southern hemisphere facility, has confirmed 40 new exoplanets found by TESS over the past decade.
Life is But a Stream: The Distribution of Planetary Systems Along Stellar Streams and their Properties
This paper uses N-body simulations to show how planetary systems survive in stellar streams, linking planet retention to a star's escape time and stream location.
Turbulent damping of fast tidal oscillations by three-dimensional Rayleigh-Bénard convection with a radiating free surface
3D simulations show fast tidal oscillations are turbulently damped by transferring kinetic energy to convection, explaining tidal dissipation in stars and planets.
A formation pathway for giant planets in S-type discs of γ-Cephei-like compact binaries
Mass transfer from circumbinary discs enables giant planet formation in close binary systems like γ-Cephei, overcoming disc truncation challenges.
The NUV transit of XO-3 b
This paper analyzes NUV and optical transits of exoplanet XO-3 b, finding a deeper NUV transit and a significant NUV transit timing offset.
Horizontal transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet
JWST observations confirm horizontal transport on a hot Jupiter's nightside causes disequilibrium chemistry by advecting dayside species.
Exploration of the inner region of the system HD 142527
High-contrast imaging of HD 142527's inner disk reveals a candidate companion and an Hα spiral, suggesting complex interactions shaping disk and planet formation.
Earth and Mars interior structures set by re-melting of the first solid mantle
This paper explains why Mars has a basal silicate layer from magma ocean re-melting, unlike Earth, due to differences in planetary size and iron enrichment.
Accessible does not mean exploitable: HiPERCAM reveals the ultra-fast rotation of 2022 OB$_5$
Asteroid 2022 OB5, a target for prospecting, is an ultra-fast rotator (1.54 min period), making surface operations challenging despite its accessibility.
