Exocomets in a planet nursery [PDF]
Nature CommunicationsEvidence for exocomets has been found in PDS 70, a young planetary system where planets are still forming. The discovery extends exocomet studies into an earlier stage of planetary evolution, when planets, planetesimals and protoplanetary discs coexist.

Exciting opportunities in planetary structural geology and tectonics: An early career perspective
Frontiers in Earth Science, 2022 The outer shells of solid planetary bodies have been all subject to deformation during their history. The nature and style of deformation strictly depends on the evolution of each planetary body.

Post-main-sequence planetary system evolution [PDF]
Royal Society Open Science, 2016 The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical

Binary Central Stars of Planetary Nebulae
Galaxies, 2020 It is now clear that a vast majority of intermediate-mass stars have stellar and/or sub-stellar companions, therefore it is no longer appropriate to consider planetary nebulae as a single-star phenomenon, although some single, isolated stars may well ...

Evolution of planetary systems in resonance [PDF]
Astronomy & Astrophysics, 2004 We study the time evolution of two protoplanets still embedded in a protoplanetary disk. The results of two different numerical approaches are presented and compared. In the first approach, the motion of the disk material is computed with viscous hydrodynamical simulations, and the planetary motion is determined by N-body calculations including exactly

The evolution of planetary nebulae [PDF]
Astronomy & Astrophysics, 2005 We investigate and discuss the expansion properties of planetary nebulae by means of 1D radiation-hydrodynamics models computed for different initial envelope configurations and central star evolutionary tracks. In particular, we study how the expansion depends on the initial density gradient of the circumstellar envelope and show that it is possible ...

Origin and Evolution of Planetary Atmospheres [PDF]
Annual Review of Earth and Planetary Sciences, 1980 Spacecraft and groundbased observations of the atmospheres of solar system objects have provided a definition of their present characteristics and have yielded clues about their past history. Table 1 presents a summary of our current knowledge of the atmospheric properties of all the planets, except Pluto, and several satellites.

Lessons from the Ionised and Molecular Mass of Post-CE PNe
Galaxies, 2022 Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to ...
