𝐻-band (top) and 𝐾-band (bottom) spectra of 2M0437b. The dark blue points are the reduced spectrum produced by the OSIRIS pipeline, the dark blue line is the 21-point running median, the magenta curve is a model of the spectrum to further correct for telluric absorption using a spectrum of an A0 star, and the green points and line are the corrected spectrum and its 21-point running median. The grey line is a model transmission spectrum for the atmosphere over Maunakea for an airmass of 1.5 and water vapor column of 1.6 mm (courtsey Gemini Orbservatory, Lord 1992). The absorption functions of key molecules (H2O, CO, CH4, HCN) computed using the HITRAN database (Mikhailenko et al. 2005; Gordon et al. 2022) and normalized by the maximum for that molecule in each bandpass are plotted at the top (blue, black, red, and orange lines, respectively. The vertical dotted lines mark H Brackett lines and the Na I doublet, and spectral features of molecules of interest are labeled. -- astro-ph.EP

CO, H2O, And CH4 In The Dusty Atmosphere Of A ≤5 Myr-old Exoplanet

by Keith CowingAugust 30, 2023August 30, 2023

Very young massive planets are sufficiently luminous by their internal heat of formation to permit detailed studies, including spectroscopy of their atmospheres with large telescopes at sufficient resolution (λ/Δλ≳1000) to […]
