X-ray flare modeling in the single giant HR 9024

Kavli Affiliate: David Huenemoerder | First 5 Authors: Paola Testa, David Garcia-Alvarez, Fabio Reale, David Huenemoerder, | Summary: We analyze a Chandra-HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at high temporal resolution, to derive plasma parameters (thermal distribution, abundances, temperature, …). […]

Objective Subclass Determination of Sloan Digital Sky Survey Unknown Spectral Objects

Kavli Affiliate: Mark SubbaRao | First 5 Authors: David Bazell, David J. Miller, Mark SubbaRao, , | Summary: We analyze a portion of the SDSS photometric catalog, consisting of approximately 10,000 objects that have been spectroscopically classified into stars, galaxies, QSOs, late-type stars and unknown objects (spectroscopically unclassified objects, SUOs), in order to investigate the […]
