FAUST XXXII. Chemically layered structures and ionisation in the disk and envelope of NGC 1333 IRAS 4C
Recent molecular line observations with high spatial resolutions have revealed vertical chemical stratification in Class I/II disks (i.e. chemical composition changing with height in the vertical…Kinematic structure and age of a Scorpius--Centaurus subcomponent: implications for PDS 70 planetary system
PDS~70, the only system with two directly imaged protoplanets embedded in their natal disk, is a benchmark for giant-planet formation theory.Competitive roles of turbulence and magnetic field on the formation of unipolar outflows in isolated molecular cloud cores
We investigate the impact of turbulence and magnetic field on the formation of unipolar outflows in the gravitational collapse of isolated low-mass cloud cores using three-dimensional non-ideal…Ammonia-Hydrogen Phase Equilibria in Planetary Envelopes from First-Principles-Based Machine-Learning Molecular Dynamics
Ammonia and hydrogen are major constituents of planets within and beyond the solar system, yet how they interact in planetary envelopes is poorly known.Dynamical response of a protoplanetary disk to an FU Ori-type outburst
Episodic accretion events onto young stars can significantly change the global structure of their surrounding protoplanetary disks.A Hectospec Spectroscopic Census of Kinematic Members in the Orion Nebula Cluster
We present a comprehensive spectroscopic census of the Orion Nebula Cluster (ONC), based primarily on low-resolution optical spectroscopy obtained with MMT/Hectospec.Survey of Orion Disks with ALMA (SODA) IV: Millimeter variability of protoplanetary disks
Short-term millimeter-wavelength variability in Class II young stellar objects (YSOs) has been considered minimal, often dismissed as very rare in ALMA-based studies on short timescales.Dust Activity Evolution and Constraints on Icy Grains in the Interstellar Comet 3I/ATLAS
We present Zwicky Transient Facility observations of the interstellar comet 3I/ATLAS to characterize its dust-activity evolution before and after perihelion.Multi-wavelength Polarization as a Probe of Planet Formation
Polarization reveals details of circumstellar disks that are not readily available from total intensity observations.A Sample of Thick-Disk Stars Hosting Hot Jupiters
We present a homogeneous analysis of 268 confirmed and candidate transiting hot-Jupiter host stars with 4800K < Teff < 6200K.Chemical Demographics of Star-forming Regions
Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines.The environments forming stellar and planetary systems
How does a star's birth environment set the mass, angular momentum and chemical complexity delivered to its planet-forming disk, and thereby whether it builds planets, brown dwarfs or stellar…The contact frontier in Galactic civilization networks: radial structure and the Galactic habitable zone
The probability of interstellar contact depends not only on the abundance of technological civilizations but also on their spatial connectivity.A Search for Dust in the Outflow of the HH212 Class 0 Protostellar System
Perhaps the most visually striking phenomenon during star formation is the ejection of material along the direction of the protostar's rotational axis.Extinction by non-spherical particles with the Nanoparticle Transition Matrix Code: perspectives for interstellar medium and exoplanetary atmospheres
The Transition Matrix formalism (T-matrix) offers an optimal solution to the problem of radiation scattering and absorption by particles characterized by a high degree of chemical and structural…OGLE-2016-BLG-0523: A Low-mass Brown Dwarf or super-Jupiter in a $>100$ au Orbit
To search for very wide-orbit binary-lens events, we cross-match microlensing events detected by OGLE-IV and KMTNet between 2011 and 2024.Gravitational Microlensing
Gravitational microlensing is a unique planet-detection method that does not rely on detecting light from the host star or planet.Constrained Diffusion for Data-Scarce Orbital Monte Carlo in Constellation Tasking
Constellation Monte Carlo results depend on the orbital population used to evaluate a tasking policy.Two Low-Mass-Ratio Microlensing Planets from High-Magnification Events: KMT-2021-BLG-0247 and MOA-2023-BLG-169
We present an analysis of two planetary microlensing events, KMT-2021-BLG-0247 and MOA-2023-BLG-169, both of which exhibit high magnifications and low planet--host mass ratios, but with markedly…COSMOS-3D: Spectro-photometric Confirmation of Shabgard, a Cool, Metal-poor Brown Dwarf in the COSMOS Field
Brown dwarfs are unique laboratories for studying cool atmospheres, the low-mass end of star formation, and the transition between stars and giant planets.
