The birth environment of planetary systems. [PDF]

open access: yesR Soc Open Sci, 2020
Star and planet formation are inextricably linked. In the earliest phases of the collapse of a protostar, a disc forms around the young star and such discs are observed for the first several million years of a star’s life.

A Population of planetary systems characterized by short-period, Earth-sized planets. [PDF]

open access: yesProc Natl Acad Sci U S A, 2016
Significance Characterizing the variety of planets and planetary systems orbiting distant stars (exoplanets) is a key ingredient to improving our understanding of the Solar System and of planet formation in general. One important observable property of a

The fragility of planetary systems [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
We specify the range to which perturbations penetrate a planetesimal system. Such perturbations can originate from massive planets or from encounters with other stars.

Beyond breakpoint – reconceptualising AMR as a symptom of planetary stress [PDF]

open access: yesnpj Antimicrobials and Resistance
Planetary boundaries range from climate change to biosphere integrity. They define the safe space for humanity. Ecosystem impacts on microbes are missing from a recent assessment showing six of nine boundaries are breached.

The New Generation Planetary Population Synthesis (NGPPS). IV. Planetary systems around low-mass stars [PDF]

open access: yesAstronomy & Astrophysics, 2021
Previous work concerning planet formation around low-mass stars has often been limited to large planets and individual systems. As current surveys routinely detect planets down to terrestrial size in these systems, a more holistic approach that reflects ...
