VizieR Online Data Catalog: Radial velocities & light curves of KELT-24 (Rodriguez+, 2019)

The Kilodegree Extremely Little Telescope (KELT) survey (http://keltsurvey.org) uses two 42 mm telescopes to discover hot Jupiters orbiting bright host stars (7<V<12), planets well-suited for detailed atmospheric characterization (Pepper et al. 2007PASP..119..923P, 2012PASP..124..230P, 2018haex.bookE.128P). With one telescope in Sonita, AZ, and the other at the South African Astronomical Observatory (SAAO) in Sutherland, South Africa, KELT surveys over 85% of the entire sky with a 20-30 minute cadence. The planetary companion orbiting HD 93148 (hereafter KELT-24 b) was identified from a joint analysis of five separate KELT-North fields that cover the celestial northern polar cap, KN25 through KN29 (although KELT-24 was only observed in two of the five fields).

The multiband photometric follow-up of KELT-24 b was obtained from the KELT Follow-Up Network (KELT-FUN, Collins et al. 2018, J/AJ/156/234). KELT-FUN is a worldwide network of amateur astronomers, small-college observatories, and observing time on the Las Cumbres Observatory telescope network (Brown et al. 2013PASP..125.1031B).

To confirm the planetary nature of KELT-24 b, 59 spectra were obtained using the Tillinghast Reflector Echelle Spectrograph (TRES; Furesz 2008, PhD thesis Univ. Szeged) on the 1.5 m Tillinghast Reflector located at the Fred L. Whipple Observatory (FLWO) on Mt. Hopkins, AZ. TRES has a resolving power of R~44000, and has been highly successful in confirming exoplanet candidates from both ground- and space-based transit surveys. We reduced the TRES spectra and extracted RVs following the procedure described in Buchhave et al. (2010, J/ApJ/720/1118) and Quinn et al. (2012, J/ApJ/756/L33) with the exception of the creation of the template spectrum used.
