BOWIE-ALIGN: A JWST comparative survey of aligned versus misaligned hot Jupiters to test the dependence of atmospheric composition on migration history
Owen, James E.; Kirk, James; López-Morales, Mercedes +20 more
A primary objective of exoplanet atmosphere characterization is to learn about planet formation and evolution, however, this is challenged by degeneracies. To determine whether differences in atmospheric composition can be reliably traced to differences in evolution, we are undertaking a transmission spectroscopy survey with JWST to compare the co…
PYSSED: an automated method of collating and fitting stellar spectral energy distributions
McDonald, Iain; Zijlstra, Albert A.; Cox, Nick L. J. +4 more
Stellar atmosphere modelling predicts the luminosity and temperature of a star, together with parameters such as the effective gravity and the metallicity, by reproducing the observed spectral energy distribution. Most observational data come from photometric surveys, using a variety of passbands. We herein present the Python Stellar Spectral Ener…
Microchannel plate response to solar energetic particles and consequences for solar-wind measurements on ESA's Vigil mission
Owen, C. J.; Nicolaou, G.; Verscharen, D. +1 more
Space weather forecasting aims at predicting the impacts of the Sun, interplanetary space, and the planetary environment on biological and technological systems. To monitor space weather, the European Space Agency is developing the Vigil mission. Vigil will carry the Plasma Analyser (PLA) instrument. We investigate the expected impact of Solar Ene…
On the nature of apparent transient sources on the National Geographic Society-Palomar Observatory Sky Survey glass copy plates
Hambly, N. C.; Blair, A.
We examine critically recent claims for the presence of above-atmosphere optical transients in publicly available digitized scans of Schmidt telescope photographic plate material derived from the National Geographic Society-Palomar Observatory Sky Survey. We employ the publicly available SuperCOSMOS Sky Survey catalogues to examine statistically t…
