(Teff,log g,[Fe/H]) Classification of Low-Resolution Stellar Spectra using Artificial Neural Networks
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. In this context, traditional star-by-star spectroscopic analysis are no longer practical. New tools are required that are capable of extracting quickly and with reasonable accuracy important basic stellar parameters cod...
متن کاملHorizontal Branch stars as AmFm / HgMn stars
Recent observations and models for horizontal branch stars are briefly described and compared to models for AmFm stars. The limitations of those models are emphasized by a comparison to observations and models for HgMn stars.
متن کاملComputing the Principal Branch of log-Gamma
The log-Gamma function is an important special function of mathematics, and its principal branch is required in many applications. We develop here the mathematics required to evaluate the principal branch to arbitrary precision, including a new bound for the error in Stirling’s asymptotic series. We conclude with a discussion of the implementation of the principal branch of the log-Gamma functi...
متن کاملHorizontal Branch stars in ω Centauri : clues about their origin from the cluster Color Magnitude Diagram
We investigate a peculiar feature at the hottest, blue end of the horizontal branch of Galactic globular cluster ω Centauri, using the high-precision and nearly complete catalog that has been constructed from a survey taken with the Advanced Camera for Survey on board the Hubble Space Telescope, that covers the inner 10 × 10 arcminutes. It is a densely populated clump of stars with an almost ve...
متن کاملThe Ages of Stars: The Horizontal Branch
Horizontal branch (HB) stars have long played a central role in the age debate. These low-mass stars, which burn helium in the core and hydrogen in a shell, are the immediate progeny of the luminous, vigorously mass-losing red giant branch (RGB) stars. Most importantly in the present context, their temperatures depend strongly on their total masses. More specifically, the lower the mass of an H...
