VizieR Online Data Catalog: Effect of stellar companions on planetary systems (Ziegler+, 2018)
Abstract
We use Robo-AO and Keck-AO to observe KOIs with detected nearby stars in multiple bands to estimate the spectral type and distance to each star. These properties allow us to quantify the probability of association between the primary and secondary components in each system. Observations in the survey were performed using the Robo-AO automated laser adaptive optics system at Palomar and Kitt Peak (Baranec et al. 2014ApJ...790L...8B, 2017arXiv170907103B; Jensen-Clem et al. 2018AJ....155...32J) that can efficiently perform large, high angular resolution surveys. We obtained high angular resolution images of 3313 KOIs with Robo-AO between 2012 July 16 and 2015 June 12 (UT) at the Palomar 1.5 m telescope. We observed 532 additional KOIs with Robo-AO between 2016 June 8 and 2016 July 15 (UT) at the Kitt Peak 2.1 m telescope. Further follow-up observations in r', i', and z' bands of 145 KOIs with nearby stars detected by Robo-AO in previous papers in the survey were performed between 2017 March 16 and 2017 June 08 (UT) at Kitt Peak by Robo-AO. We observed 10 candidate multiple systems in J, H, and K with the NIRC2 camera behind the Keck-II laser guide star adaptive optics system (van Dam et al. 2006PASP..118..310V; Wizinowich et al. 2006PASP..118..297W), on 2017 August 8-10 (UT). These 10 multiple KOI systems were targeted due to uncertainty in association between the primary and secondary stars with only Robo-AO visible-band photometry.
