Electric Potential Patterns Forecasting in the Southern Hemisphere with Deep Learning Techniques
Space weather disturbances driven by the solar wind can degrade satellite navigation, disrupt radio communications, and threaten power infrastructure, making accurate forecasting of the…Binary-pulsar Timing: A 3D Solar-System Accelerometer and Unknown-Source Probe
The acceleration of the Solar System barycenter (SSB) offers a unique precision probe of the local gravitational environment, enabling searches for otherwise invisible gravitating sources such as…Metal-Poor Stars as Metal-Rich Impostors via Planet Engulfment
Planet engulfment leads to planetary mass accretion and angular momentum deposition into the stellar envelope.JWST Observations of the Metal-poor T Dwarf WISEA J155349.96+693355.2: The First Brown Dwarf Associated with the Gaia-Enceladus Milky Way Substructure
We present JWST NIRSpec and MIRI observations of the metal-poor T dwarf WISEA J155349.96+693355.2.The geometric origin of the thermal eccentricity law
The distribution $f(e)=2e$ is commonly referred to as the `thermal eccentricity distribution' of Keplerian binaries.Triggering star formation by free-floating planets
Recently, a population of free-floating planets has been discovered in the Galaxy.Metal-poor Brown Dwarf Kinematics from JWST NIRSpec Spectroscopy
Galactic archaeology relies on stellar kinematics and chemical abundances to identify various stellar populations and associations.NGTS clusters survey - VII. An Enigmatic Short-Period Circumsecondary Disk Candidate in Orion
Young stellar systems provide key insights into the processes governing star/planet formation, often exhibiting complex and evolving photometric variability.Laboratory Evidence that Methanol-Rich Ice Mantles Lower Methyl Formate Binding Energies
Complex organic molecules are widely detected in star-forming regions and are important precursors to prebiotic species.A Multiband Catalog of Infrared-Excess Sources in the Vela-Carina Region: VVVX, DECaPS, and GLIMPSE
Multiwavelength surveys of the Galactic midplane enable the identification of infrared-excess sources, signatures of circumstellar material, though high extinction and crowding hinder detection.1I/'Oumuamua-like objects's SFDs with older, current and future surveys
Interstellar Objects (ISOs) may provide direct evidence of planetesimals ejected from early-stage solar systems.Reinforcement learning for post-coronagraphic wavefront control
Direct imaging of exoplanets is limited by the extreme contrast between the star and the planets, which is mitigated using a coronagraph.Graph neural networks for exoplanet atmospheres
Calculating disequilibrium chemistry in exoplanet atmospheres remains a significant computational bottleneck in atmospheric retrievals.Operational Range Bounding in Spectroscopy: A Safety Cage Framework for Machine Learning Models
Ensuring the reliability of black-box machine learning models in safety-critical space missions remains a significant challenge, particularly when ground-truth is unavailable for validation.Continuous Learning of Gravity Field Irregularities Around Small Bodies via Neural Hamiltonian ODEs
We propose to learn the unknown dynamics in the proximity of a small body directly from tracking data, representing them as a feed-forward neural network embedded in the system Hamiltonian.Physics-Informed Multi-Task Surrogate Model for the Martian Nightside Thermosphere
Modeling the Martian nightside thermosphere remains challenging due to sparse in situ sampling and strong coupling among transport, magnetic, and seasonal processes.
