A Global Perspective with Updated Constraints on the Ultra-hot Jupiter WASP-19b: Atmospheric Properties and Stellar Activity
Abigail A. Tumborang, Jessica J. Spake, Heather A. Knutson +7
We present a detailed reanalysis of the atmospheric properties of WASP-19b, an ultra-hot Jupiter (1.14 M Jup, 1.41 R Jup) orbiting an active Sun-like star every 0.79 day. We reanal…
An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet
Nikolay Nikolov, David K. Sing, Jonathan J. Fortney +20
Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of clo…
Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab
N. Nikolov, D. K. Sing, J. Goyal +20
We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…
Re-visit of HST FUV observations of hot-Jupiter system HD 209458: No Si III detection and the need for COS transit observations
G. E. Ballester, L. Ben-Jaffel
The discovery of OI atoms and CII ions in the upper atmosphere of HD 209458b, made with the Hubble Space Telescope Imaging Spectrograph (STIS) using the G140L grating, showed that…
A Search for Methane in the Atmosphere of GJ 1214b via GTC Narrow-Band Transmission Spectrophotometry
P. A. Wilson, K. D. Colón, D. K. Sing +11
We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument. Using tuneable filters we obser…
Exoplanet HD 209458b : Evaporation strengthened
A. Vidal-Madjar, A. Lecavelier des Etangs, J. -M. Desert +4
Following re-analysis of Hubble Space Telescope observations of primary transits of the extrasolar planet HD209458b at Lyman-alpha, Ben-Jaffel (2007, BJ007) claims that no sign of…
