Water- and metal-rich atmospheres on compact hot mini-Neptunes lose mass more slowly than H/He cases at high enrichment levels due to enhanced cooling and higher mean molecular weight.
False positive probabilties for all Kepler Objects of Interest: 1284 newly validated planets and 428 likely false positives

abstract
We present astrophysical false positive probability calculations for every Kepler Object of Interest (KOI)---the first large-scale demonstration of a fully automated transiting planet validation procedure. Out of 7056 KOIs, we determine that 1935 have probabilities <1% to be astrophysical false positives, and thus may be considered validated planets. 1284 of these have not yet been validated or confirmed by other methods. In addition, we identify 428 KOIs likely to be false positives that have not yet been identified as such, though some of these may be a result of unidentified transit timing variations. A side product of these calculations is full stellar property posterior samplings for every host star, modeled as single, binary, and triple systems. These calculations use 'vespa', a publicly available Python package able to be easily applied to any transiting exoplanet candidate.

Two extremely low-density Jupiter-sized planets on long-period orbits around TOI-791 were confirmed via ground-based photometry and TTV-derived masses.
Updated RM modeling framework in TLCM validated on nine systems and applied to TOI-135 to measure sky-projected obliquity λ = 55.6° with ~11° uncertainties.
Barnard's Star planets have masses 0.19-0.84 M_earth, are tidally locked, unlikely to retain primary atmospheres, and possess mantles rich in ferropericlase with less than half Earth's water capacity and radiogenic heating.
