Titolo: | The LAMOST spectroscopic survey of stars in the Kepler field of view: Activity indicators and stellar parameters | Autori: | Molenda-Żakowicz, Joanna FRASCA, Antonio De Cat, Peter CATANZARO, Giovanni |
Data pubblicazione: | 2017 | Rivista: | EPJ WEB OF CONFERENCES | Titolo del volume in cui è pubblicato il poster: | Wide-Field Variability Surveys: A 21st Century Perspective – 22nd Los Alamos Stellar Pulsation | Curatore/i del volume in cui è pubblicato il contributo: | Catelan, M.; Gieren, W. | Numero: | 152 | Da pagina:: | 04002 | Abstract: | We summarize the results of the completed first round of the LAMOST-Kepler project, and describe the status of its on-going second round. As a result of the first round of this project, the atmospheric parameters (T<SUB>eff</SUB>, log g, and [Fe/H]), the spectral classification (spectral type and luminosity class), and the radial velocities (RV) have been measured for 51,385 stars. For 4031 stars, we were able to measure the projected rotational velocity, while the minimum detectable v sin i was 120 km s<SUP>-1</SUP>. For 8821 stars with more than one observation, we computed the χ-square probability that the detected RV variations have a random occurrence. Finally, we classified 442 stars as chromospherically active on the basis of the analysis of their Hα and Ca II-IRT fluxes. All our results have been obtained from the low-resolution (R ∼ 1800) spectroscopic observations acquired with the LAMOST instrument. <P />Based on observations collected with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) located at the Xinglong Observatory, China. | Titolo del convegno: | Wide-Field Variability Surveys: A 21st Century Perspective – 22nd Los Alamos Stellar Pulsation – Conference Series Meeting | Luogo del convegno: | San Pedro de Atacama, Chile | Periodo del convegno: | November 28 – December 2, 2016 | URI: | http://hdl.handle.net/20.500.12386/26770 | URL: | https://www.epj-conferences.org/articles/epjconf/abs/2017/21/epjconf_puls2017_07003/epjconf_puls2017_07003.html | ISSN: | 2101-6275 | ISBN: | 978-2-7598-9024-8 | DOI: | 10.1051/epjconf/201715204002 | Bibcode ADS: | 2017EPJWC.15204002M | Fulltext: | open |
