TL;DR
This study expands the nearby M-dwarf star catalog using Gaia data, detecting new companions and refining multiplicity statistics, thereby enhancing understanding of the Solar Neighborhood's low-mass stellar population.
Contribution
The paper presents an updated, volume-limited M-dwarf catalog incorporating Gaia data, identifying new low-mass companions and refining multiplicity and separation distributions.
Findings
Detected four new likely bound companions.
Updated the projected separation distribution with a peak at 7.91 au.
Refined the M-dwarf multiplicity rate to 22.7%.
Abstract
The Solar Neighborhood is dominated by stars smaller, colder, and fainter than the Sun: the M dwarfs. If we are to understand the context in which the Sun formed and evolved, then we must investigate the system architectures of our low-mass neighbors. We have therefore carried out the Pervasive Overview of Kompanions of Every M Dwarf in Our Neighborhood (POKEMON) speckle survey of nearby M-dwarf primaries. We created the survey with the goal of observing a volume-limited (north of -30 degrees) sample of M-dwarf primaries through M9 out to 15 pc at diffraction-limited resolution. Pre-Gaia parallax measurements yielded a catalog of 454 nearby M-dwarf primaries. However, the precise astrometry from Gaia indicated that there are additional low-mass sources within 15 pc. Here we present the POKEMON-Distance Limited Catalog (POKEMON-DLC), a supplemental catalog that consists of speckle…
