Revealing the Origins of Galactic Globular Clusters via their Mg–Al Abundances

open access: yesThe Astrophysical Journal Letters
Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifying their origins is crucial for revealing galaxy properties at early times.

All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity

open access: yesThe Astrophysical Journal, 2023
We explore the kinematic and chemical properties of the Monoceros stellar overdensity by combining data from the Two Micron All Sky Survey, Wide-field Infrared Survey Explorer, APOGEE, and Gaia.

Local Stellar Kinematics from RAVE data - VII. Metallicity Gradients from Red Clump Stars [PDF]

open access: yes, 2016
We investigate the Milky Way Galaxy's radial and vertical metallicity gradients using a sample of 47,406 red clump stars from the RAVE DR4. This sample is more than twice the size of the largest sample in the literature investigating radial and vertical ...

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

open access: yesJournal of the Association for Information Science and Technology, Volume 77, Issue 1, Page 92-107, January 2026.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

open access: yesThe Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution

NLTE Analysis of Y i and Y ii in the Atmospheres of FGK Stars

open access: yesThe Astrophysical Journal, 2023
The nonlocal thermodynamical equilibrium (NLTE) line formation of Y i and Y ii is considered in 1D LTE model atmospheres of FGK-type stars. The model atom was constructed with the most up-to-date atomic data, including quantum cross sections and rate ...

PERICLES: A Set of Empirical Rotational Isochrones Modeled on Cool Dwarfs in Open Clusters and Wide Binaries

open access: yesAstronomische Nachrichten, Volume 347, Issue 1, January 2026.
ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Uncertainties in models of stellar structure and evolution [PDF]

open access: yes, 2014
Numerous physical aspects of stellar physics have been presented in Ses- sion 2 and the underlying uncertainties have been tentatively assessed. We try here to highlight some specific points raised after the talks and during the general discus- sion at ...

A Cross‐Disciplinary Analysis of AI Policies in Academic Peer Review

open access: yesLearned Publishing, Volume 39, Issue 1, January 2026.
ABSTRACT Rapid advances of artificial intelligence (AI) have substantially impacted the field of academic publishing. This study examines AI integration in peer review by analysing policies from 439 high‐ and 363 middle‐impact factor (IF) journals across disciplines. Using grounded theory, we identify patterns in AI policy adoption. Results show 83% of
