Tracing Accretion and Inner-Disk Gas Evolution in the Orion Nebula via Br-alpha and CO
We present a systematic spectroscopic study of hydrogen Brackett-alpha (Br-alpha) and carbon monoxide (CO) fundamental-band (4.3-5.2 micron) emission from a homogeneous sample of 0.2-1.5 Msun…Twisted Pseudodisk and Asymmetric Mass Accretion on the Circumstellar Disk II: Parameter Survey
Using three-dimensional magnetohydrodynamic simulations accounting for ohmic dissipation, we investigate the long-term evolution of the infalling envelope for $\sim 100,000$\,yr after protostar…Transients and Stellar Activity as Revealed by Ultraviolet Diagnostic Tracers
Ultraviolet (UV) observations offer unique insights into transient and variable astrophysical phenomena, from the Sun and nearby stars to supernovae and star-forming galaxies.Blackbody evolution and circumstellar medium properties of broad-lined H-rich superluminous supernovae
Broad-lined H-rich superluminous supernovae (SLSNe II) tend to show signs of interaction, including a UV excess compared to a blackbody function.The nearby Type II supernova 2024ggi beyond 600 days: circumstellar interaction and dust formation
The Type II SN 2024ggi is one of the nearest core-collapse SNe to have exploded in recent decades.From Giant Envelopes to Rapidly Contracting Cores in Rotating Population III Stars from $500$ to $1000 \, M_\odot$
Population III (Pop III) stars link the chemical enrichment of the early Universe to the formation of the first massive black holes, yet their evolution remains poorly understood at extreme masses.An upper limit on Galactic OB+black hole binaries from SDSS-V
Binaries composed of a luminous OB star and a black hole (BH) are a key evolutionary link between massive stellar binaries and merging compact-object binaries, but only a handful are known and their…Henrietta Leavitt's classical Cepheid relation
The Leavitt & Pickering (1912) mean period-magnitude relation for SMC Cepheids exhibits correlated residuals relative to modern Gaia $B_G$ and Johnson $V$ photometry ($r_{δV/δL12}\approx0.76$).An asteroseismic age estimate for the Pleiades using a neural-network emulator of rotating $δ$ Scuti pulsation models
Asteroseismology of $δ$ Sct stars has strong potential for determining the ages of young stars through individual mode fitting.The $R$-Process Alliance: On J0010$-$1735, an Accreted, Chemically Unusual, Metal-poor Star with $R$-process Enhancement
We present a detailed chemo-dynamical analysis of the chemically peculiar very metal-poor ([Fe/H]$=-2.22\pm 0.11$) Milky Way (MW) halo star, 2MASS J00101758$-$1735387 (hereafter J0010-1735)…An Ultraviolet Instrument on the Habitable Worlds Observatory: Considerations and Capability Trades on the Multi-Object, Integral-field, and High-resolution modes of a potential UVI
The Habitable Worlds Observatory (HWO) is NASA's next-generation astrophysics platform, delivering transformative capability in the search for life and study of the origins of the universe.X-Shooter view of planetary nebulae microstructures I: The case of NGC 7009 knots
The properties of NGC 7009 knots are investigated by employing UV-to-near-infrared data from the X-Shooter spectrograph.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.A Spectroscopic Census of Cluster White Dwarfs from DESI, LAMOST, and SDSS
Gaia has substantially expanded the sample of candidate white dwarfs (WDs) in open clusters, but many remain without spectroscopic characterization.Stellar discs and intermediate-mass black holes in galactic nuclei II. Fragmenting the disc and forming the S-stars in a live nuclear star cluster
We present direct $N$-body simulations of a stellar disc around the supermassive black hole Sgr~A*, perturbed by an intermediate-mass black hole (IMBH) and embedded in a live nuclear star cluster.The Binary Fraction of Milky Way Field Stars in DESI: Dependence on Chemical Abundance
Binary populations encode information about the physical conditions of star formation and the subsequent evolution of stellar populations.Isotopic ratios as probes of star formation and the origin of molecular gas in the Central Molecular Zone
The Central Molecular Zone (CMZ) contains most of the dense molecular gas in the Milky Way but forms stars at a surprisingly low rate.Gravitational Microlensing
Gravitational microlensing is a unique planet-detection method that does not rely on detecting light from the host star or planet.Probing Massive Star Formation with Intrinsic Multiplicity Constraints from TESS Eclipsing Binaries
Massive stars play a central role in stellar and galactic evolution as progenitors of supernovae, neutron stars, black holes, and gravitational wave sources.EWOCS-XI: Anisotropic expansion and shear in the cluster Westerlund 1. A 2D kinematic analysis with Gaia DR3
Westerlund 1 (Wd1) is one of the Milky Way's most massive young clusters, in which heavy extinction and field contamination have historically hampered its kinematic characterization.
