DMPP-7 hosts a confirmed 0.72 Saturn-mass planet at P=4.93 days; HD 67200 and HD 2134 show moderate evidence for 2.7-2.8 day low-mass candidates that remain unconfirmed.

A circumstellar plasma torus fed by exoplanet volcanism would imprint detectable atomic absorption lines, letting astronomers estimate volcanic outgassing rates.
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.
No bursty planet-induced radio emission detected from five inactive M dwarfs; upper limits constrain GJ 367 b magnetosphere to <0.8 G under assumed stellar wind conditions.
