First Results from JACKS: A VLA Ammonia View of Gas Heating and Star-forming Cores in the Central Molecular Zone
The Central Molecular Zone (CMZ) combines warm molecular gas, strong turbulence, and a star-formation rate below that expected from its dense-gas reservoir.The Pristine survey XXXI. A stream offset from the Stream: very metal-poor stellar debris trailing 100$^{\circ}$ from the LMC-SMC system
The stellar counterpart to the $200^\circ$-long HI Stream from the Clouds probes their tidally stripped stellar populations and constrains their interaction history and structure before infall into…A Large-Sample Study of Interstellar Reddening in Galactic Star Clusters
The interstellar reddening (extinction or absorption) is caused mainly by the dust grains of different sizes and compounds.Cepheid Metallicity in the Leavitt Law (C-MetaLL) survey: X First spectroscopic characterization of Galactic Type II Cepheids and calibration of the Period-Wesenheit-Metallicity relations
Type II Cepheids (T2Cs) are Population II pulsating stars that serve as distance indicators through their period--luminosity relation.Survey of Surveys Data Release 3. Homogenised stellar parameters across nine spectroscopic surveys
Large spectroscopic surveys have measured atmospheric parameters for millions of Milky Way stars, but differences in instruments, wavelength ranges, analysis methods, and assumptions introduce…The cold substellar frontier in JWST Extragalactic surveys: a robust parallax measurement yields the most distant known ultra-cold Y dwarf
We present an analysis of JADES-GS-BD-5, an extremely cold Y dwarf identified in the JADES/GOODS-South field.How fast is the fastest-rotating O-type star in the Galaxy?
{Rapid rotation distorts massive stars, making parameters from spherical models inclination-dependent.The kinematic Kelvin-Helmholtz instability-driven dynamo: implications for merging compact objects
Binary neutron star (BNS) mergers excite a Kelvin--Helmholtz instability (KHI) in the shear layer between them.The formation and evolution of Wolf-Rayet stars with temperature-dependent winds
Massive stars strongly influence their environments through their radiation, stellar winds and core-collapse supernovae, while their own evolution is strongly shaped by wind mass loss.A Machine Learning Approach to Coupling Photoionization & Multi-Frequency Radiation Hydrodynamics
We use machine learning (ML) to couple photoionization microphysics to radiation hydrodynamic simulations of line-driven winds.The vertical distribution of molecular gas in the fourth quadrant of the Milky Way
The vertical distribution of molecular gas in the Milky Way disk is poorly studied, especially in the 4th quadrant and the far side of the Galaxy.Metamorphic novae. I. Gaia22alz -- Violent relaxation starting from static evolution
Gaia22alz (nova Vel 2022) shows characteristic properties in its light curves and spectral evolution similar to slow novae HR Del, V723 Cas, and V5558 Sgr.Brewing another binary in the Teapot: Nandou=Phi Sagittarii
The iconic Teapot asterism in Sagittarius is particularly rich in intermediate-mass stars in multiple systems.Searching for Signatures of i-process Nucleosynthesis in Metal-Rich, Lead-rich Barium Stars
The intermediate neutron-capture process ($i$-process) has been invoked to explain the peculiar compositions of carbon-enhanced metal-poor (CEMP) stars enriched in both slow- ($s$) and rapid- ($r$)…Identifying Compact Object Candidates using Gaia DR3 Astrometric Accelerations and Jerks
Gaia Data Release 3 (DR3) provides astrometric measurements for more than a billion sources, hundreds of thousands of which have non-single-star astrometric solutions that indicate deviations from…Harmonic Angular Mapping Method for Binary Microlensing Grid Search
Searching for binary-lens microlensing solutions is computationally demanding because of the complex parameter space and the large number of trial models required.Chemical abundances of a Galactic Centre ejecta discovered in DESI
Chemical abundances in the Galactic Centre (GC) are challenging to measure because of high extinction, crowding, and distance, and are typically limited to the brightest AGB and M giants observed in…An all-sky catalogue of Be transition stars from WISE and Gaia
We present an all-sky catalogue of classical Be stars undergoing transitions between quiescent B-type and active Be-star phases, based on Gaia DR3 astrometry and multi-epoch mid-infrared photometry…Stellar wind variability in OB stars and its effect on mass-loss determinations
Virtually all stellar winds of OB stars exhibit variability in one spectral diagnostic or another.Episodic Protostellar Outflows: A Proper Motion Study in Serpens South
Serpens South is a notable protostellar cluster with signatures of recent star formation, including a high protostellar fraction.
