Machine Learning Techniques for Stellar Light Curve Classification [PDF]
, 2018 We apply machine learning techniques in an attempt to predict and classify stellar properties from noisy and sparse time series data. We preprocessed over 94 GB of Kepler light curves from MAST to classify according to ten distinct physical properties ...

45. Stellar Classification [PDF]
Transactions of the International Astronomical Union, 1985 During the report period (1982–1984) several symposia, colloquia, and workshops in the field of stellar classification were held. These include: IAU Symposium No. 111 ”Calibration of Fundamental Stellar Quantities” (Como, May 24 29, 1984, ed. D. S. Hayes et al.), IAU Colloquium No.

The Nature of Blue Stars with Mid-infrared Excesses in the Large Magellanic Cloud
The Astrophysical Journal Supplement Series, 2023 We present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were selected with the criteria of U − B < 0 and V < 17 from the potential young ...

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.

COMMISSION 45: STELLAR CLASSIFICATION [PDF]
Proceedings of the International Astronomical Union, 2010 The business meeting of Commission 45 was held on Friday, 7 August. It was attended by the Vice-President of the Commission (who chaired the meeting in the absence of the President) as well as nine other members of the Commission. Attendance was limited, as usual, by the unavoidable occurrence of parallel sessions.

Spectral Classification of Galaxies Along the Hubble Sequence [PDF]
, 1995 We develop a straightforward and quantitative two-step method for spectroscopically classifying galaxies from the low signal-to-noise (S/N) optical spectra typical of galaxy redshift surveys. First, using \chi^2-fitting of characteristic templates to the

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

The impact of mass loss on star cluster formation. II. Numerical N-body integration & further applications [PDF]
, 2002 We subject to an N-body numerical investigation our analysis of Paper I on the survival of stellar clusters undergoing rapid mass loss. We compare analytical tracks of bound mass-fraction {\it vs} star formation efficiency $\epsilon$ to those obtained ...
