The Galactic rotation curve from the ALS III catalogue of OB Stars
The Galactic rotation curve reveals the radial mass distribution of the Milky Way, but its determination depends on the tracer population.ARENA: Active Region attENtion Aggregation for interpretable solar flare prediction
Predicting solar flares is a challenging space-weather forecasting problem with potentially significant impacts on Earth's upper atmosphere, including disruptions to radio communications.Physics Informed Neural Network for Multi-dimensional Turbulent Self-gravitating Flows
Molecular clouds exhibit complex, multi-scale dynamics driven by the interplay of turbulence, self-gravity, and gas pressure.One-Million-Year-Old Nascent Eclipsing Binaries in the LMC
The light curves of nascent eclipsing binaries (EBs) feature sinusoidal reflection effects as a hot B-type main-sequence (MS) primary irradiates the near side of a cool, low-mass, pre-MS companion.The Milky Way's Early Disk Was Built in Bursts. II. The Multi-component Age-Metallicity Structure of the High-$α$ Disk
Whether the high-$α$ disk experienced a continuous or episodic star-formation history remains an open question.A 13 Year Black Hole Microlensing Survey in Omega Centauri
Star clusters are born with massive stars that leave behind a large population of stellar mass black holes.The ALMA-QUARKS survey: A Keplerian Circumbinary Disk Candidate in the High-mass Star-forming Region IRAS 08303-4303
We present the ALMA Band 6 continuum and molecular line observations of IRAS 08303-4303, a high-mass star-forming region, with an angular resolution of $\sim 0.3''$ ($\sim 700$ au at the distance of…Slow Massive-Star Formation and the O-Star ZAMS Deficit
The scarcity of optically visible O stars near the theoretical zero-age main sequence (ZAMS) has puzzled astronomers for over four decades.Collapsars Are Not Heavy $r$-Process Factories
Collapsar disks are proposed sources of $r$-process elements, but neutron-rich disk ejecta require gas to be both neutronized in the disk and ejected before accretion.The Galactic Center Reference Frame: A 30-Year Solution
Stellar orbits probe the metric of and mass around the Sgr A* massive black hole.simesh: A Python Framework for Quantitative Analysis of Native AMR Data from MPI-AMRVAC
Adaptive mesh refinement (AMR) is widely used in large-scale astrophysical simulations, but the resulting multilevel data are challenging to analyze quantitatively.Ballistic mixing: stellar mergers drive internal mixing in extremely massive stars, with implications for proto-globular cluster pollution
Extremely massive stars, with masses of $10^3$-$10^4$ M$_\odot$, have been proposed as potential sources of the chemical enrichment associated with multiple populations in globular clusters.Stellar Loci X: Selection of Nitrogen-Rich Giants Using GALEX NUV and Synthetic SDSS Photometry
Nitrogen-rich (N-rich) field stars (likely second-generation escapees from globular clusters) provide a powerful, but currently sample-limited, probe of globular-cluster disruption in the Galactic…Charting the Galactic Underworld II: Strategies for Identifying BHs and NSs with LISA
Stellar-mass black holes (BHs) and neutron stars (NSs) observed by space-based gravitational-wave detectors offer constraints on binary stellar evolution that are complementary to those from ground-…AGB-star Mass Transfer Products in Stellar Streams as Tracers of Density in Dissolved Star Clusters
The least dense globular clusters (GCs) appear to host the highest fractions of stars with chemical signatures of mass transfer from asymptotic giant branch (AGB) companions.Gone Without a Bang: A Search for Failed Core-Collapse Supernovae in ZTF and Predictions for Rubin and Roman
The core-collapse of massive stars (${\geq}10\ \rm M_\odot$) usually takes the form of a supernova, but in some cases may lead to a direct collapse, leading to a failed core-collapse supernova…JWST observations of the planetary nebula NGC 6302 IV: PAH spectral characteristics, formation and evolution
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in Oxygen-rich planetary nebulae (PNe), yet their formation and evolution in these environments is an open question.A Potential New Dimension of Astrophysical Aromatic Functionalization: Phosphaethynyl (CP) Derivatives
Quantum chemical computations outline a thermodynamically viable, low-temperature, gas-phase formation pathway for phosphaethynyl cyclopropenylidene ($c$-C$_3$HCP), resulting from cyclopropenylidene…Constraining Solid HNCO and Its Environment in Open JWST Data with Laboratory Spectra
The presence of HNCO in the gaseous phase is well known for the interstellar medium, but the molecule is not detected yet in the solid phase.Phakoseismology: Asteroseismology of gravitationally microlensed stars
Asteroseismology relies on disk-integrated photometry or radial velocities, in which geometric cancellation suppresses modes of high spherical degree ($l\geq4$).
