Radiation shielding of protoplanetary discs in young star-forming regions
Maite J. C. Wilhelm, Simon Portegies Zwart, Claude Cournoyer-Cloutier +4
Protoplanetary discs spend their lives in the dense environment of a star forming region. While there, they can be affected by nearby stars through external photoevaporation and dy…
Birth cluster simulations of planetary systems with multiple super-Earths: initial conditions for white dwarf pollution drivers
Katja Stock, Dimitri Veras, Maxwell X. Cai +2
Previous investigations have revealed that eccentric super-Earths represent a class of planets which are particularly effective at transporting minor bodies towards white dwarfs an…
Oort cloud Ecology II: The chronology of the formation of the Oort cloud
Simon Portegies Zwart, Santiago Torres, Maxwell X. Cai +1
We present a chronology of the formation and early evolution of the Oort cloud by simulations. These simulations start with the Solar System being born with planets and asteroids i…
Inside-Out Planet Formation: VI. Oligarchic Coagulation of Planetesimals from a Pebble Ring?
Maxwell X. Cai, Jonathan C. Tan, Simon Portegies Zwart
Inside-Out Planet Formation (IOPF) is a theory addressing the origin of Systems of Tightly-Packed Inner Planets (STIPs) via {\it in situ} formation and growth of the planets. It pr…
Lucky planets: how circum-binary planets survive the supernova in one of the inner-binary components
Fedde Fagginger Auer, Simon Portegies Zwart
A planet hardly ever survives the supernova of the host star in a bound orbit, because mass loss in the supernova and the natal kick imparted to the newly formed compact object cau…
Effects of stellar density on the photoevaporation of circumstellar discs
Francisca Concha-Ramírez, Maite J. C. Wilhelm, Simon Portegies Zwart +2
Circumstellar discs are the precursors of planetary systems and develop shortly after their host star has formed. In their early stages these discs are immersed in an environment r…
