The fragility of planetary systems [PDF]
Monthly 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.

Planetesimal rings as the cause of the Solar System’s planetary architecture [PDF]
Nature Astronomy, 2021 Astronomical observations reveal that protoplanetary disks around young stars commonly have ring- and gap-like structures in their dust distributions. These features are associated with pressure bumps trapping dust particles at specific locations, which ...

Evolved Climates and Observational Discriminants for the TRAPPIST-1 Planetary System [PDF]
Astrophysical Journal, 2018 The TRAPPIST-1 planetary system provides an unprecedented opportunity to study terrestrial exoplanet evolution with the James Webb Space Telescope (JWST) and ground-based observatories.

The formation of planetary systems with SPICA [PDF]
Publications of the Astronomical Society of Australia, 2021 Abstract In this era of spatially resolved observations of planet-forming disks with Atacama Large Millimeter Array (ALMA) and large ground-based telescopes such as the Very Large Telescope (VLT), Keck, and Subaru, we still lack statistically relevant information on the quantity and composition of the material that is building the planets, such as ...

Transit timing variations in the WASP-4 planetary system [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Transits in the planetary system WASP-4 were recently found to occur 80 s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that confirm the existence of transit timing variations, and are well fitted

PARAMETER OPTIMIZATION FOR A THERMAL SIMULATION OF AN URBAN AREA [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 Urban heat island (UHI) phenomenon is a significant challenge in urban planning, and accurate temperature predictions are crucial for effective decision-making. The choice of material parameters is crucial to simulate a realistic temperature distribution

Dynamical instability and its implications for planetary system architecture [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We examine the effects that dynamical instability has on shaping the orbital properties of exoplanetary systems. Using N-body simulations of non-EMS (Equal Mutual Separation), multi-planet systems we find that the lower limit of the instability timescale
