Deep Learning for Galaxy Mergers in the Galaxy Main Sequence [PDF]

open access: yes, 2019
Starburst galaxies are often found to be the result of galaxy mergers. As a result, galaxy mergers are often believed to lie above the galaxy main sequence: the tight correlation between stellar mass and star formation rate.

The embedded clusters DBS 77, 78, 102, and 160-161 and their link with the interstellar medium [PDF]

open access: yes, 2016
Aims. We report a study of the global properties of some embedded clusters placed in the fourth quadrant of the Milky Way to clarify some issues related with their location into the Galaxy and their stellar formation processes. Methods.

Stellar spectrum classifier [PDF]

open access: yes, 1970
Stellar classification is accomplished by correlating holograms of classified spectra with the Fourier transform of the spectral images to be ...

Kepler Input Catalog: Photometric Calibration and Stellar Classification

open access: yes, 2011
We describe the photometric calibration and stellar classification methods used to produce the Kepler Input Catalog (KIC). The KIC is a catalog containing photometric and physical data for sources in the Kepler Mission field of view; it is used by the ...

Automated Classification of Stellar Spectra. II: Two-Dimensional Classification with Neural Networks and Principal Components Analysis [PDF]

open access: yes, 1997
We investigate the application of neural networks to the automation of MK spectral classification. The data set for this project consists of a set of over 5000 optical (3800-5200 AA) spectra obtained from objective prism plates from the Michigan Spectral

Automated Classification of Stellar Spectra using the Sloan Digital Sky Survey [PDF]

open access: yes, 2019
The classification of stellar spectra is a fundamental task in stellar astrophysics. There have been many explorations into the automated classification of stellar spectra but few that involve the Sloan Digital Sky Survey (SDSS).

(Teff,log g,[Fe/H]) Classification of Low-Resolution Stellar Spectra using Artificial Neural Networks [PDF]

open access: yes, 1999
New generation large-aperture telescopes, multi-object spectrographs, and large format detectors are making it possible to acquire very large samples of stellar spectra rapidly.

Galaxy Zoo: the dependence of morphology and colour on environment [PDF]

open access: yes, 2008
We analyse the relationships between galaxy morphology, colour, environment and stellar mass using data for over 100,000 objects from Galaxy Zoo, the largest sample of visually classified morphologies yet compiled.

Observational evidence for the origin of X-ray sources in globular clusters [PDF]

open access: yes, 2007
Low-mass X-ray binaries, recycled pulsars, cataclysmic variables and magnetically active binaries are observed as X-ray sources in globular clusters. We discuss the classification of these systems, and find that some presumed active binaries are brighter
