The Environmental Dependence of Star Cluster Demographics

Jianling Tang, Kathryn Grasha, Mark R. Krumholz +1

Both the star cluster mass function and the lifetimes of clusters may vary with galactic environment, but measuring this variation is challenging because in observational surveys r…

The Cluster Completeness Correction Calculator (C-4): A Neural-Network framework and pilot application to the LEGUS Survey of NGC 628

Jianling Tang, Kathryn Grasha, Tomasz Różański +2

Integrated-light star cluster catalogues in external galaxies are subject to complex, often poorly-characterised selection effects that can bias inferred cluster demographics and i…

High-fidelity stellar extinction with Gaia and APOGEE -- I. The method and a new extinction curve

Jie Yu, Luca Casagrande, John A. Taylor +9

The scarcity of high-fidelity extinction measurements remains a bottleneck in deriving accurate stellar properties from Gaia parallaxes. In this work, we aim to derive precision ex…

Observational constraints on the origin of the elements. X. Combining NLTE and machine learning for chemical diagnostics of 4 million stars in the 4MIDABLE-HR survey

Nicholas Storm, Maria Bergemann, Tomasz Różański +9

We present the 4MOST-HR resolution Non-Local Thermal Equilibrium (NLTE) Payne artificial neural network (ANN), trained on new FGK spectra with 16 elements computed in NL…

SPICE -- modelling synthetic spectra of stars with non-homogeneous surfaces

M. Jabłońska, T. Różański, L. Casagrande +4

In the era of large time-domain spectro-photometric surveys, surface variations such as starspots, chemical inhomogeneities, pulsations, rotational distortions, and binary interact…

Solving the mystery of extreme light variability in the massive eccentric system MACHO 80.7443.1718

Piotr A. Kołaczek-Szymański, Piotr Łojko, Andrzej Pigulski +2

The evolution of massive stars is heavily influenced by their binarity, and the massive eccentric binary system MACHO 80.7443.1718 (ExtEV) serves as a prime example. This study exp…
