Decoy and disclosure radii of invariant shape descriptors
A recognizer that compares rotation-invariant descriptors sees a surface only up to the fiber of the descriptor.Reflex instabilities I: Boundaries makes grid-based disc simulations frame-dependent
If the mass distribution within an accretion disc is asymmetric, it will exert a gravitational pull on its central object.Reflex instabilities II: The reflex motion of the central object drives at least seven instabilities in accretion discs
This series of papers studies the stability of accretion discs to the reflex motion of the central object under the gravitational pull of the disc itself.First Direct Identification of a Multi-Star Microlens System Hosting a Planet
Nearly 25 years have passed since gravitational microlensing delivered its first exoplanet discoveries.Molecular hydrogen formation on dust: The impact of gas-dust drift on formation efficiency
Molecular hydrogen is predominantly formed on dust-grain surfaces in the interstellar medium, where relative gas-dust motion can arise in dynamically active environments.Spectral Energy Distribution and Polarimetric Properties of Dust in the Interstellar Comet 3I/ATLAS
The interstellar comet 3I/ATLAS exhibits unusual polarimetric properties compared with Solar System comets, while constraints on its fundamental physical properties, such as dust albedo and…The 200-300 GHz Survey for 18 Class II Disks in the Ophiuchus Star-Forming Complex
We measured the 198-310 GHz flux densities of 18 Class II protoplanetary disks in the Ophiuchus star-forming complex using the Submillimeter Array (SMA).Measuring the Age and Initial Composition of Interstellar Objects
Measuring the age and composition of interstellar objects is necessary to understand their origins.AEGIS: Differentiable Mars Climate Model with Neural Closures
General circulation models (GCMs) are the primary tool for simulating planetary atmospheres.Post-Training Quantization of Autoregressive Weather Models
Advancements in high-resolution numerical weather prediction (NWP) and data assimilation (DA) have shaped the developments in deep learning (DL) architectures emulating atmospheric dynamics.Water enhances the formation of refractory sulfur in interstellar ices
Sulfur is the tenth most abundant element in space, yet it is strongly depleted in the gas phase of dense interstellar regions, suggesting sequestration in dust grain components that are difficult…A Missing Latent, Not a Missing Simulator: Radius-Augmented Inference for Real JWST Retrieval
Amortized simulation-based inference (SBI), which is trained on radiative-transfer simulators, recovers exoplanet atmospheres accurately on synthetic James Webb Space Telescope (JWST) spectra but…A Bayesian Inference Framework for Binary Lens Events Fully Incorporating Higher-Order Effects
Higher-order effects, such as microlensing parallax and lens orbital motion, are essential for characterizing the physical properties of microlensing planetary systems including their masses and…Testing KMTNet--PRIME Optical--Near-Infrared Source-Color Constraints in KMT-2024-BLG-0211 and KMT-2024-BLG-1522
We present analyses of two 2024 microlensing events, KMT-2024-BLG-0211 and KMT-2024-BLG-1522, jointly observed by KMTNet in the optical and PRIME in the near-infrared.Detecting Extragalactic Exoplanets With Fast Radio Burst Nanolensing
Fast Radio Bursts (FRBs) are spatially and temporally compact sources at cosmological distances.Constraining exoplanet population parameters with Kepler and simulation-based inference
In the context of the rapidly growing field of galactic exoplanet population studies, we present an exoplanet simulator capable of generating synthetic populations for millions of stars in a few…SIFARI: Self-Supervised Interferometric Fitting for Astronomical Radio Imaging
Radio-interferometric images are reconstructed from sparsely sampled visibilities, and CLEAN-based imaging can struggle with spatial filtering, complex morphologies, and uncertainty quantification.GameDev: GPU-accelerated model for dust evolution
Grain growth and fragmentation through dust collisions in protoplanetary disks are strongly coupled with dust dynamics.Synthesis of organo-phosphorous species in space: the reaction of P$^+$ with C$_2$H$_2$
Despite its low cosmic abundance, phosphorus is a bioessential element whose prebiotic availability and incorporation into biomolecules remain open questions.On the Compositions of Interstellar Objects
As physical samples of distant planetary systems, the compositions of interstellar objects (ISOs) should correlate with the properties of their diverse parent stars.
