VizieR Online Data Catalog: Four new eclipsing mid M-dwarf systems from MEarth (Irwin+, 2018)
Abstract
We operate the MEarth project, an all-sky survey using two robotic telescope arrays to search for transiting planets orbiting fully convective M-dwarfs within 33 pc by obtaining high-cadence differential photometry (Nutzman & Charbonneau 2008PASP..120..317N). This survey is also highly sensitive to eclipsing binaries, which present much larger photometric signals than transiting planets, and has been optimized for efficient recovery of objects with long orbital periods. Target selection for MEarth-North is described in detail in Nutzman & Charbonneau (2008PASP..120..317N), and for MEarth-South in Irwin et al. (2015csss...18..767I). All four targets presented here were selected for observation based on photometric distance estimates placing them within 33 pc, a volume limit inherited from the work of Lepine (2005, J/AJ/130/1680), upon which our original target selection was based. The MEarth data themselves, data reduction, and analysis methods have been described in detail in previous papers (Irwin et al. 2011ApJ...727...56I, 2011, J/ApJ/742/123; Berta et al. 2012AJ....144..145B; Newton et al. 2016, J/ApJ/821/93). The objects presented here were detected during the 2011-2017 observing seasons, during which time the configuration of both instruments was relatively stable, with all observations taken using the same RG715 filter bandpass.
