Stellar spectral classification and feature evaluation based on a random forest [PDF]
Research in Astronomy and Astrophysics, 2019 With the availability of multi-object spectrometers and the design and operation of some large scale sky surveys, the issue of how to deal with enormous quantities of spectral data efficiently and accurately is becoming more and more important. This work

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 ...

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

45. Stellar Classification (Classification Stellaire) [PDF]
Transactions of the International Astronomical Union, 1997 This report covers research in the field of stellar classification in the period July 1993 to June 1996. It is divided into several sections which were written by experts in each subfield. I want to thank them for their effort and cooperation. To conserve space, all references are given with only one name followed by a + sign if there are additional ...

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