VizieR Online Data Catalog: 2yrs of eclipse data & precise RVs for LP661-13 (Dittmann+, 2017)
Abstract
MEarth-south, like its northern counterpart, consists of eight f/9 40cm Ritchey-Chretien telescopes on German equatorial mounts. The telescopes are located at the Cerro-Tololo International Observatory (CTIO) in Chile. The telescopes are automated and take data on every clear night.
We obtained RV measurements with the Tillinghast Reflector Echelle Spectrograph (TRES) on the 1.5m Tillinghast reflector located at the Fred Lawrence Whipple Observatory (FLWO) on Mt. Hopkins, Arizona (R=44000). We obtained 14 observations of LP 661-13 with TRES, with eight exposures taken in the 2014 observing season (2014 February 18-2014 March 28) and six taken in the 2015 observing season (2014 December 27-2015 January 06). Follow-up photometric observations of both primary and secondary eclipses were performed with the MEarth-south telescopes. We observed 11 unique eclipse events with six different telescopes. We have obtained 9173 individual observations of LP 661-13, with 5098 observations being in-eclipse measurements and 4075 out-of-eclipse measurements. (2 data files).- Publication:
