Surface Nitrogen enrichment from the LMC to the Early Universe: the roles of rotation, overshooting and mass loss
The strong nitrogen (N) features observed in high-redshift galaxies, such as GN-z11, with JWST point to an efficient source of N production in the early Universe.Galactic-Scale Distribution of 10Be and Its Implications for the Early Solar System 10Be/9Be
Meteoritic inclusions indicate that the early Solar System contained a substantial abundance of the short-lived radionuclide 10Be.Tracking the evolution of sub-Neptunes. I. Gyrochronology of planet hosting stars
Stellar age is fundamental for reconstructing planetary-system evolution but remains difficult to determine for unevolved main-sequence stars.As a matter of reconstruction -- varying the magnetic Prandtl number in implicit large eddy simulations
The magnetic Prandtl number ($\mathrm{Pm}$), the ratio of viscosity to magnetic diffusivity, spans many orders of magnitude in astrophysical plasmas.A VLT/CRIRES+ study of helium 1.083$μ$m absorption features towards the inner Orion Nebula
JWST NIRCam F115W observations towards the inner Orion Nebula revealed a diverse array of previously unknown dark features.A Low-Dimensional Chemical Representation of High-Resolution Stellar Disk Spectra: Residual Abundance Signatures
Stellar abundances are generated by complex chemical enrichment pathways yet show strong correlation structure.Detection of HNCOH+ in the interstellar medium
Only five out of the $\sim$350 molecules detected in the interstellar medium (ISM) carry the isocyanate functional group (NCO), the essential substructure of peptide bonds in proteins.Four-hundred Very Metal-poor Stars Studied with LAMOST and Subaru. IV. Heavy Element Enhanced Stars
We perform a homogeneous analysis of 82 heavy-element-enhanced metal-poor stars from the\\ LAMOST/Subaru sample, including 64 $r$-process-enhanced stars, 2 limited-$r$ stars, and 16 stars exhibiting…Playing CHESS with stars II. Homogeneous analysis of high-resolution optical spectra for a sample of 135 giants in 14 bulge globular clusters
Bulge globular clusters are key tracers of the complex formation history of the Galactic bulge, as they retain information on its past star-formation episodes.On the Proper 3D Modeling of Orbits in Wide Binary Gravity Tests
A gravitationally-bound system of wide binary stars with precise 3D relative displacement $\mathbf{r}$ and velocity $\mathbf{v}$ can allow a Keplerian orbit reconstruction for an assumed…The $δ$ Scuti instability strip and period-luminosity relation as seen by TESS and Gaia DR3
We present an asteroseismic survey of 1,526,218 A- and F-type stars in and around the $δ$ Scuti instability strip using TESS 10-minute cadence data, which resolve the full $δ$ Scuti pulsation…PyMsOfa 2.0: A Pure-Python Implementation of the IAU Standards of Fundamental Astronomy Service
Astrometric calculations require authoritative algorithms so that every result is correct and reproducible.Understanding the origin of silver in metal-poor stars based on the non-local thermodynamic equilibrium analysis of Ag I lines
Silver is a poorly observed neutron-capture element, and understanding its Galactic production history requires accurate abundances for stellar samples covering a broad metallicity range.Atmospheric Parameter Determination of RR Lyrae Stars With Mephisto Multi-band Photometry
Phase-resolved atmospheric parameters of pulsating stars, including RR Lyrae stars and Cepheids, are essential for studying stellar structure and pulsation physics and for establishing accurate…Black Hole Spin Evolution in Magnetized Accretion Flows
Black hole (BH) spin grows as accretion supplies angular momentum and decreases as magnetically driven jets remove it, driving the BH toward an equilibrium spin, $a_{\rm \star; eq}$.Infrared spectroscopy of the longest-period Galactic Mira variables from Palomar Gattini-IR: Identification of a candidate thermally pulsing Super-Asymptotic Giant Branch star
The population of extremely long-period Mira variables in the Milky Way remains poorly characterized.The Bochum Survey of the Southern Galactic Disk: IV. Multi-Band Photometry
The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a $6^\circ$-wide stripe in the southern galactic disk from September 2010 to September 2019.A morpho-kinematic view of the Necklace nebula
We present a morpho-kinematic study of the Necklace Nebula based on spatially resolved spectroscopic observations and 3D modeling performed with the SHAPE software.Detailed chemo-dynamical characterization of four elusive Milky Way star clusters
A variety of faint and observationally challenging stellar systems has been discovered in the Milky Way in the last decades.A Collimated Protostellar Outflow Likely Driven by Jet and Reshaped by Environment in the Sagittarius C Cloud of the Central Molecular Zone
The Central Molecular Zone (CMZ) at the center of the Galaxy provides a nearby laboratory for studying star formation under extreme physical and chemical conditions.
