Revised Masses for Low Density Planets Orbiting the Disordered M-dwarf System TOI-1266

We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two transiting sub-Neptunes at 10.8 and 18.8 days. We measure masses of M_{b}=4.01~\pm~0.55~M_{\oplus} for TOI-1266 b and M_{c}=2.00~\pm~0.72~M_{\oplus} for TOI-1266 c. Our mass measurements agree with existing HARPS-N observations... Show more
