High-Resolution Transit Spectroscopy of Warm Saturns
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +4
We present high-resolution optical transmission spectroscopy of two sub-Saturn mass transiting exoplanets, HAT-P-12b and WASP-69b. With relatively low densities and high atmospheri…
Retrieving Temperatures and Abundances of Exoplanet Atmospheres with High-Resolution Cross-Correlation Spectroscopy
Matteo Brogi, Michael R Line
Hi-resolution spectroscopy (R > 25,000) has recently emerged as one of the leading methods to detect atomic and molecular species in the atmospheres of exoplanets. However, it has…
The High-Resolution Transmission Spectrum of HD 189733b Interpreted with Atmospheric Doppler Shifts from Three-Dimensional General Circulation Models
Erin Flowers, Matteo Brogi, Emily Rauscher +2
The signature of wind patterns caused by the interplay of rotation and energy redistribution in hot Jupiters is detectable at high spectral resolution, yet no direct comparison has…
Measuring the D/H Ratios of Exoplanets and Brown Dwarfs
Caroline V. Morley, Andrew J. Skemer, Brittany E. Miles +5
The relative abundance of deuterium and hydrogen is a potent tracer of planet formation and evolution. Jupiter and Saturn have protosolar atmospheric D/H ratios, a relic of substan…
Diagnosing aerosols in extrasolar giant planets with cross-correlation function of water bands
Lorenzo Pino, David Ehrenreich, Romain Allart +6
Transmission spectroscopy with ground-based, high-resolution instruments provides key insight into the composition of exoplanetary atmospheres. Molecules such as water and carbon m…
The GAPS Programme with HARPS-N at TNG XVI: Measurement of the Rossiter-McLaughlin effect of the transiting planetary systems HAT-P-3, HAT-P-12, HAT-P-22, WASP-39 and WASP-60
L. Mancini, M. Esposito, E. Covino +43
We characterised five transiting planetary systems (HAT-P-3, HAT-P-12, HAT-P-22, WASP-39 and WASP-60) and determined their sky-projected planet orbital obliquity through the measur…
