The two-planet transiting system LHS 1140 has been extensively observed since its discovery in 2017, notably with $Spitzer$, HST, TESS, and ESPRESSO, placing strong constraints on the parameters of the M4.5 host star and its small temperate exoplanet

The Solar Neighborhood. XLIII: Discovery of New Nearby Stars with pm < 0.18 arcsec yr-1 (TINYMO sample)

Autor: Riedel, Adric R., Silverstein, Michele L., Henry, Todd J., Jao, Wei-Chun, Winters, Jennifer G., Subasavage, John P., Malo, Lison, Hambly, Nigel C.

We have conducted a novel search of most of the southern sky for nearby red dwarfs having low proper motions, with specific emphasis on those with proper motion < 0.18 arcsec yr-1, the lower cutoff of Luyten's classic proper motion catalog. We used a

Optical and Near-Infrared Radial Velocity Content of M Dwarfs: Testing Models with Barnard's Star

Autor: Artigau, Étienne, Malo, Lison, Doyon, René, Figueira, Pedro, Delfosse, Xavier, Astudillo-Defru, Nicola

High precision radial velocity (RV) measurements have been central in the study of exoplanets during the last two decades, from the early discovery of hot Jupiters, to the recent mass measurements of Earth-sized planets uncovered by transit surveys.
