VizieR Online Data Catalog: Stellar properties & RV variability for M-dwarfs (Pass+, 2023)

This work is part of a series of papers presenting the results of the volume-complete spectroscopic survey of 0.10-0.30M_ȯ M dwarfs within 15pc, defined in Winters+ (2021, J/AJ/161/63). The sample totals 413 stars and excludes M dwarfs that are close companions (separations <4") to more massive primaries, as the spectra would be strongly contaminated by the brighter star. Between 2016 and 2022, we collected four high-resolution spectra of each of these 413 stars using the Tillinghast Reflector Echelle Spectrograph (TRES; R=44000) at the 1.5m telescope at the Fred Lawrence Whipple Observatory for sources with δ{>}-15° and the CTIO HIgh ResolutiON (CHIRON; R=80000) spectrograph at the Cerro Tololo Inter-American Observatory 1.5m telescope for sources with δ{<}-15°.

After making some cuts described in Section 2, 200 M dwarfs remain in our sample (Figure 1), of which we observe 122 with TRES and 78 with CHIRON.
