Hubble PanCET: An extended upper atmosphere of neutral hydrogen around the warm Neptune GJ 3470 b
V. Bourrier, A. Lecavelier des Etangs, D. Ehrenreich +16
GJ 3470b is a warm Neptune transiting an M-dwarf star at the edge of the evaporation desert. It offers the possibility of investigating how low-mass, close-in exoplanets evolve und…
Detection of Helium in the Atmosphere of the Exo-Neptune HAT-P-11b
Megan Mansfield, Jacob L. Bean, Antonija Oklopčić +11
The helium absorption triplet at a wavelength of 10,833 Å has been proposed as a way to probe the escaping atmospheres of exoplanets. Recently this feature was detected for the fir…
Spectrally resolved helium absorption from the extended atmosphere of a warm Neptune-mass exoplanet
R. Allart, V. Bourrier, C. Lovis +7
Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These extended atmospheres are difficult to observe because their main spectral signature - neutral…
Atomic iron and titanium in the atmosphere of the exoplanet KELT-9b
H. Jens Hoeijmakers, David Ehrenreich, Kevin Heng +10
The chemical composition of an exoplanet is a key ingredient in constraining its formation history. Iron is the most abundant transition metal, but has never been directly detected…
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…
