VizieR Online Data Catalog: Planet candidates from K2 campaigns 5-8 (Petigura+, 2018)
Abstract
In this paper, we provide a catalog of planet candidates and eclipsing binaries from the second year of K2 operations, corresponding to campaigns 5-8 (C5-C8). We generated light curves for 87913 stars observed by K2 during C5-C8 using the publicly available k2phot Python package (https://github.com/petigura/k2phot). The general methodology is described in previous works (Crossfield et al. 2015ApJ...804...10C, 2016, J/ApJS/226/7; Petigura et al. 2015ApJ...811..102P). As a part of our team's standard follow-up efforts, we obtained optical spectra of 143 C5-C8 target stars using the HIgh Resolution Echelle Spectrometer (HIRES; Vogt et al. 1994SPIE.2198..362V) on the Keck I 10 m telescope. We gathered spectra for the purpose of improving host star parameters and to place limits on the presence of companion stars with small separations through searches for spectroscopic binaries (SB2s). We aimed to obtain a spectrum of every K2OI brighter than V=14.0 mag. For G stars, this limit corresponds roughly to Kp=13.6 mag.
