The Carnegie-Irvine Galaxy Survey. X. Bulges in Stellar Mass–based Scaling Relations
The Astrophysical Journal Supplement Series, 2022 We measure optical colors for the bulges of 312 disk galaxies from the Carnegie-Irvine Galaxy Survey and convert their previously available R -band structural parameters to stellar-mass parameters.

Application of convolutional neural networks for stellar spectral classification [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Due to the ever-expanding volume of observed spectroscopic data from surveys such as SDSS and LAMOST, it has become important to apply artificial intelligence (AI) techniques for analysing stellar spectra to solve spectral classification and regression

Classification of Stellar Spectra [PDF]
International Astronomical Union Colloquium, 1990 SummaryThe objectives of this exercise are to gain familiarity with the appearance of the spectra of stars, to understand some of the temperature and luminosity criteria used to classify spectra, and to gain insights into the relationship between the appearance of stellar spectra and physical conditions in stellar atmospheres.

Automatic Extraction and Classification of Low-Dispersion Objective-Prism Stellar Spectra
Open Astronomy, 2000 An automatic method of spectral classification from low-dispersion objective prism images is developed. The distribution of early- and late-type stars inside stellar complexes and their surrounding regions can lead to important clues on the star ...

, 2021 The year 1943 saw the introduction of the Morgan-Keenan (MK) classification scheme and this replaced the existing Harvard Classification scheme. Both stellar classification scheme are fundamentally grounded in the field of spectroscopy.

The AMBRE project: Results from the MATISSE analysis of the ESO-FEROS archived spectra
EPJ Web of Conferences, 2012 The goal of AMBRE, a joint project between ESO and the Observatoire de la Cote d’Azur, is to provide a homogeneous determination of the stellar parameters (including mean metallicity and some chemical abundances) for the archived spectra of the FEROS ...

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations
The Astrophysical Journal Supplement Series, 2023 Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

Architecture of Hierarchical Stellar Systems and Their Formation
, 2021 Accumulation of new data on stellar hierarchical systems and the progress in numerical simulations of their formation open the door to genetic classification of these systems, where properties of a certain group (family) of objects are tentatively ...
