VizieR Online Data Catalog: The solar neighborhood LI. RECONS & TESS obs. (Kar+, 2024)

The A Trail to Life Around Stars (ATLAS) project is described in Section 2.

Our selection criteria resulted in 32 systems with 69 reported exoplanets that have at least 3yr of RECONS observations in the ongoing program (Henry+ 2018, J/AJ/155/265). These 32 M dwarfs that constitute the ATLAS sample are shown in the observational H-R diagram of Figure 1, are listed in Table 1, and comprise the set for which we discuss our variability measurements from RECONS and TESS observations. See Section 3.

Since 1999, the REsearch Consortium On Nearby Stars (RECONS; www.recons.org) program has conducted astrometric and photometric measurements of red dwarfs in the solar neighborhood with the Small and Moderate Aperture Research Telescope System (SMARTS)/Cerro Tololo Inter-American Observatory (CTIO) 0.9m telescope in Chile. Observations are made using Johnson-Kron-Cousins VRI filters with central wavelengths of 5438Å, 6425Å, and 8075Å, respectively. See Section 4.

We use TESS data to study 23 of the 32 stars in the ATLAS sample that have been observed so far for these midterm variability signatures. See Section 5.
