New MAROON-X observations of HAT-P-70b detect multiple neutral and ionized metals with day-to-night wind signatures and demonstrate that ionization-aware retrievals yield abundance ratios closer to solar values except for enhanced nickel.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
Atmospheric retrievals yield C/O = 0.57±0.01, [M/H] = 0.18±0.05, and 12CO/13CO ≈ 95 for 2MASS J0249-0557 c, matching benchmark brown dwarfs and favoring star-like gravitational collapse over disk accretion.
Moderate to high spectral resolution (R>1000) provides higher sensitivity for detecting key molecules like H2O and O2 in Earth analogs than low resolution (R~140), as correlated speckle noise can suppress detections at low resolutions.

Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Moderate to high spectral resolution (R>1000) provides higher sensitivity for detecting key molecules like H2O and O2 in Earth analogs than low resolution (R~140), as correlated speckle noise can suppress detections at low resolutions.
