Revealing the companion of NGC 1850-BH1
The nature of the system NGC 1850-BH1 is discussed controversially in the literature.The Clouds in the "Middle Ages" I. Star formation history and chemical abundances in the LMC
The LMC is a benchmark galaxy for studying stellar evolution, chemical enrichment, and galaxy interactions due to its proximity and intermediate metallicity.The dearth of dustless HdC stars in the Magellanic Clouds: A metallicity-driven white dwarf merger mass effect
Hydrogen-deficient carbon (HdC) stars are rare supergiants believed to form through the merger of two white dwarfs (WDs)."Helium Enrichment Law": The Relation Between Helium and Metal Enrichment in Stars in FIRE-3 Simulations of Milky Way-mass Galaxies
Helium abundance is a key input to stellar models that are used to infer accurate ages, masses, and compositions for individually resolved stars in the Milky Way (MW), underpinning Galactic…The UKIRT M33 Monitoring Project - VII. A 15-year K-band photometric catalogue of long-period variable stars in the central kiloparsec of M33
We present a homogenised K-band photometric catalogue for the central ${\approx}12$ arcmin$^2$ (${\approx}0.9$ kpc$^2$) of the Triangulum spiral galaxy M33, combining four independent PSF-based…Machine learning applications in the heliosphere
Space weather is the study of the near-Earth impact of the processes on the Sun.Machine Learning Applications in the Solar Interior and Atmosphere
The solar interior and atmosphere constitute a strongly coupled, multiscale dynamical system defined by continuous temporal evolution.Gaia DR3 Compact Binary Candidates Constrained by Radial Velocity Measurements
Astrometry enables the most direct determination of the orbital elements and component masses of compact binaries.Multiplicity of Massive stars in the Milky Way (M3W). II. The brightest single O stars: variability and systemic velocities
(ABRIDGED) M3W studies the dynamical properties of massive stars in the solar vicinity, such as their systemic velocities, which are affected by variability effects: pulsations, line infilling by…Explainable Prediction of High-Speed Solar Wind Streams driven by Coronal Holes via Topological Data Analysis
High-speed solar wind streams (HSSs) originating from coronal holes (CHs) are an important driver of recurrent geomagnetic activity.The Impact of Flyby Interactions on the Rotation of Open Clusters
The Gaia astrometric mission has provided the first evidence for the bulk rotation of open clusters.The Stellar Populations of Resolved Galaxies
The study of galaxies outside the Milky Way using observations of resolved stellar populations has experienced extraordinary growth over the past two decades.Testing Pre-main-sequence Evolutionary Models with Gaia and SPHEREx Observations of Canis Major North
Pre-main-sequence (PMS) evolutionary models can assign different ages across stellar mass within the same population.The formation of silicon-carbon chain molecules in IRC+10216
Linear silicon-carbon chain molecules, SiC$_n$ (n = 3--6), have been detected in the circumstellar envelope of the carbon-rich AGB star IRC+10216.Properties of Oxygen-rich Asymptotic Giant Branch stars in the LMC and the Milky Way
We investigate the properties of oxygen-rich asymptotic giant branch (OAGB) stars in the LMC and the Milky Way using infrared (IR) color-magnitude diagrams, two-color diagrams, spectral energy…Contributions of massive stars and classical novae to Galactic 26Al
The radioactive isotope 26Al is believed to be mainly produced by massive stars and ejected into the interstellar medium through their winds and supernovae.Theoretical Pulsation Properties of RR Lyrae and Type II Cepheids in the JWST and Roman photometric systems
RR Lyrae (RRL) stars and Type II Cepheids (T2Cs) are key standard candles and tracers of old stellar populations.Late Epoch Infrared Spectroscopy and Two-Component 3D Photoionization Modeling of Classical Nova V5668 Sgr
V5668 Sgr is an Fe II classical nova (CN) that exploded on 15 March 2015.On the Evolution of Circumstellar Disks Modified by the Presence of a Binary
Stars form within circumstellar disks, and some binary stars develop circumbinary disks surrounding the pair.Binary Dynamics and Mergers in a Stellar Disk and the Formation of Dusty Objects in the Galactic Center
For more than a decade, observers have been tracking a population of enigmatic dusty objects orbiting the central supermassive black hole of the Milky Way, Sagittarius A$^\star$ (SgrA$^\star$).
