HAT-P-70b Archives - Astrobiology

Kp – Vsys maps for species which we claim a detection or a tentative detection in HAT-P-70b’s atmosphere with 2 transits from the MAROON-X spectrograph. White dashed lines indicate the expected position of the signal, assuming a symmetric planet with a static atmosphere. Peaks of the cross-correlation function are shown as white regions near the expected position. The peaks show a slight offset in Vsys, indicative of the presence of strong winds in the atmosphere. The standard deviation is calculated with from a box delimited by Vsys = −100 km s−1 and Vsys = 0 km s−1 -- astro-ph.EP
