Mineral-facilitated Aqueous Synthesis Of Hydrogen Cyanide From Prebiotically Abundant Amino Acids For Chemical Evolution
![[L] The detrended and phase-folded RV time series of GJ 1132 b (top) and GJ 1132 c (bottom). Different draws of the Keplerian models from our posterior are superimposed in black. The different colored markers correspond to different RV time series. Binned data points are shown as red squares. [R] Phase-folded and detrended RV time series of LTT 3780 b (top) and LTT 3780 c (bottom). The best-fit Keplerian model is superimposed in black. The different colors and markers correspond to different RV time series.
