Aggregation and charging of mineral cloud particles under high-energy irradiation
Nanna Bach-Møller, Christiane Helling, Uffe G. Jørgensen +1
It is known from Earth that ionizing high-energy radiation can lead to ion-induced nucleation of cloud condensation nuclei in the atmosphere. Since the amount of high-energy radiat…
A search for transit timing variations in the HATS-18 planetary system
John Southworth, A. J. Barker, T. C. Hinse +23
HATS-18b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We pres…
Transmission spectroscopy with VLT FORS2: a featureless spectrum for the low-density transiting exoplanet WASP-88b
Petros Spyratos, Nikolay Nikolov, John Southworth +10
We present ground-based optical transmission spectroscopy of the low-density hot Jupiter WASP-88b covering the wavelength range 4413-8333 Å with the FORS2 spectrograph on the Very…
Ground-Based Transmission Spectroscopy with FORS2: A featureless optical transmission spectrum and detection of HO for the ultra-hot Jupiter WASP-103b
J. Wilson, N. P. Gibson, N. Nikolov +11
We report ground-based transmission spectroscopy of the highly irradiated and ultra-short period hot-Jupiter WASP-103b covering the wavelength range 400-600 nm using the…
OGLE-2017-BLG-0406: Microlens Parallax Reveals Saturn-mass Planet orbiting M-dwarf Host in the Inner Galactic Disk
Yuki Hirao, David P. Bennett, Yoon-Hyun Ryu +93
We report the discovery and analysis of the planetary microlensing event OGLE-2017-BLG-0406, which was observed both from the ground and by the satellite in a solar…
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…
