The Solar Neighborhood LVI: The RMSTAR Catalog of the Nearest 3352 M Dwarf Systems and 305 of their Wide Companions
Madison R. LeBlanc, Tim M. Johns, Todd J. Henry +8
We present the RMSTAR (RECONS M STAR) catalog, a 25 pc volume-limited and effectively volume-complete sample of the nearest 3352 M dwarf systems and their 305 wide stellar and 9 br…
Hubble Science in the 2030s White Paper: High-Contrast Optical and UV Spectroscopy with HST/STIS
K. Ward-Duong, J. Debes, J. Aguilar +11
The Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope currently stands as the sole space-based astronomical facility providing visible-light coronagraphic i…
The Solar Neighborhood LIV: 54 Orbits of M Dwarf Multiples within 30 Parsecs with Speckle Interferometry at SOAR
Eliot Halley Vrijmoet, Andrei Tokovinin, Todd J. Henry +3
We present 1066 speckle measurements of M dwarf multiples observed over 2021-2024, all taken with HRCam on the Southern Astrophysical Research 4.1 m telescope. Among these, 900 obs…
Are We There Yet? Challenges in Quantifying the Frequency of Earth Analogs in the Habitable Zone
Rachel B. Fernandes, Samson Johnson, Galen J. Bergsten +43
Searching for life elsewhere in the universe is one of the most highly prioritized pursuits in astronomy today. However, the ability to observe evidence of Earth-like life through…
The Solar Neighborhood. LV. M Dwarf Twin Binaries -- One in Five Twin Sibling Pairs Are Mismatched in Activity and/or Rotation
Andrew A. Couperus, Todd J. Henry, Aman Kar +3
We report on a study of 36 pairs of `twin' M dwarfs in wide binaries and assess how similarly the stars behave. Stars in each twin pair have BP, RP, , , and differing b…
A Demonstration of Interstellar Navigation Using New Horizons
Tod R. Lauer, David H. Munro, John R. Spencer +51
As NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen…
