Periodic Reporting for period 2 - FOUR ACES (Future of upper atmospheric characterisation of exoplanets with spectroscopy)
Reporting period: 2018-12-01 to 2020-05-31
As of 31 May 2020, the team has published 68 articles in international refereed journals, receiving a total of 1163 citations (source: NASA ADS). Among these 68 articles, 6 were published in high-impact interdisciplinary journals (5 in Nature and 1 in Science). FOUR ACES team members are lead authors of 17 of articles out of these 68 (5 are led by the project PhD students), including 3 articles in Nature. Green open access has been enforced for all publications through the arXiv server.
Milestone results are
- The detection of iron condensation across the nightside of an ultra hot gas giant exoplanet (Ehrenreich et al. 2020, Nature 580, 597; PR: https://www.eso.org/public/news/eso2005/)
- The discovery of a misaligned planetary system, where the planet is evaporating (Bourrier et al. 2018a, Nature 553, 477; PR: https://www.unige.ch/communication/communiques/en/2017/cdp181217/)
- The detection of metallic vapour in a giant exoplanet hotter than a star (Hoeijmakers et al. 2018, Nature 560, 453; PR: https://www.unige.ch/communication/communiques/en/2018/iron-and-titanium-in-the-atmosphere-of-an-exoplanet/).
- The first detection of helium escaping from a bloated exoplanet (Spake et al. 2018, Nature 557, 68) and the first detailed measurement of the shape and dynamics of an escaping cloud of helium around an exoplanet (Allart et al. 2018, Science 362, 1384; PR: https://www.unige.ch/communication/communiques/en/2018/une-planete-gonflee-comme-un-ballon/).
- The detection of a second case of evaporating Neptune-mass exoplanet (Bourrier et al. 2018b, A&A 620, A147; PR: http://hubblesite.org/news_release/news/2018-52).
