Coevolution of Dust Growth and Gravitational Instability in Massive Protostellar Disks
Massive protostellar disks are expected to sustain high accretion rates through gravitational instability, while dust growth may modify their opacity, cooling efficiency, and stability.A combined HST and JWST analysis of the stellar population in Draco II
Draco II (Dra II) is one of the faintest and most metal-poor Milky Way satellites known, yet its nature as either an ultra-faint dwarf galaxy or an extended globular cluster remains debated.Ammonia Fitting of Multiple Velocity Components in High-Mass Star-Forming Regions
We perform a multiple velocity component analysis of ammonia (NH$_3$) gas from KEYSTONE, a Green Bank Telescope survey covering 11 giant molecular clouds (GMCs) at distances from 0.7 to 2.7 kpc.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…The Milky Way's Early Disk Was Built in Bursts. I. Evidence from Low-angular-momentum, High-$α$ Stars Scattered Out of the Protodisk by Merger Events
Stars born in the high-$α$ disk can later acquire low angular momentum through dynamical scattering during early merger events.20,000 Rotation Periods in Nearby Open Clusters and Moving Groups from ZTF and ASAS-SN
Open clusters provide uniquely powerful laboratories for studying stellar evolution because their members share a common age and chemical composition.J-PLUS: Identifying Outlier Spectral Energy Distributions in the Fourth Data Release Using Unsupervised Machine Learning
The selection of candidates belonging to rare or underrepresented stellar populations, as well as novel objects, is essential for spectroscopic follow-up.IMF-aware N-body forward modelling of membership selection functions for young open clusters
We present an IMF-aware N-body forward-modelling framework, in which the stellar initial mass function (IMF) is an explicit input, to quantify the membership selection functions of open clusters…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.Reading Between the Lines: How Much Information Remains After Fitting a Stellar Spectrum?
What if we could model 100% of a stellar spectrum?Gaia in Technicolor. I. A Simple Variability-Encoded Color-Magnitude Diagram
The Hertzsprung-Russell diagram is one of the most important tools in stellar astrophysics.$N$-body simulations of the open cluster M67 -- I: global cluster properties
The most recent Gaia data releases have seen the construction of many open cluster catalogues containing thousands of open clusters.Extended J-band spectroscopy of red supergiants: parameter identifiability and metallicity robustness
Red supergiants (RSGs) provide a near-infrared metallicity diagnostic complementary to optical hot-supergiant spectroscopy, but their low-resolution extragalactic use requires tests of parameter…The GAGE survey. I. Deep multi-band stellar variability characterization and automated classification toward Baade's window
Long-term photometric surveys of the Galactic bulge are vital for characterizing its stellar populations and structure, providing a foundation for next-generation facilities.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.Analysis of Binary O-type Star Systems Using Recurrent Neural Networks
This work presents an initial analysis of the estimation of effective temperature and surface gravity for simulated O-type binary systems using a recurrent neural network.A machine-learning-driven dataset of 144,111 polycyclic aromatic hydrocarbon infrared spectra for interpreting aromatic infrared bands
The interpretation of interstellar aromatic infrared bands (AIBs) relies on reference spectral libraries, but the chemical space covered by existing databases remains incomplete relative to the vast…
