Asteroids were born bigger: An implication of surface mass ablation during gas-assisted implantation into the asteroid belt
Rafael Ribeiro de Sousa, Andre Izidoro, Rogerio Deienno +1
The origins of carbonaceous asteroids in the asteroid belt is not fully understood. The leading hypothesis is that they were not born at their current location but instead implante…
The Exoplanet Radius Valley from Gas-driven Planet Migration and Breaking of Resonant Chains
Andre Izidoro, Hilke E. Schlichting, Andrea Isella +3
The size frequency distribution of exoplanet radii between 1 and 4 is bimodal with peaks at 1.4 and 2.4 , and a valley at 1.8…
Internal or external magma oceans in the earliest protoplanets -- perspectives from nitrogen and carbon fractionation
Damanveer S. Grewal, Johnny D. Seales, Rajdeep Dasgupta
When the extent of protoplanetary melting approached magma ocean (MO)-like conditions, alloy melts efficiently segregated from the silicates to form metallic cores. The nature of t…
Planetesimal rings as the cause of the Solar System's planetary architecture
Andre Izidoro, Rajdeep Dasgupta, Sean N. Raymond +3
Astronomical observations reveal that protoplanetary disks around young stars commonly have ring- and gap-like structures in their dust distributions. These features are associated…
An upper limit on late accretion and water delivery in the Trappist-1 exoplanet system
Sean N. Raymond, Andre Izidoro, Emeline Bolmont +9
The Trappist-1 system contains seven roughly Earth-sized planets locked in a multi-resonant orbital configuration, which has enabled precise measurements of the planets' masses and…
A very early origin of isotopically distinct nitrogen in inner Solar System protoplanets
Damanveer S. Grewal, Rajdeep Dasgupta, Bernard Marty
Understanding the origin of life-essential volatiles like N in the Solar System and beyond is critical to evaluate the potential habitability of rocky planets. Whether the inner So…
Rates of protoplanetary accretion and differentiation set nitrogen budget of rocky planets
Damanveer S. Grewal, Rajdeep Dasgupta, Taylor Hough +1
The effect of protoplanetary differentiation on the fate of life essential volatiles like nitrogen and carbon and its subsequent effect on the dynamics of planetary growth is unkno…
The effect of a strong pressure bump in the Sun's natal disk: Terrestrial planet formation via planetesimal accretion rather than pebble accretion
André Izidoro, Bertram Bitsch, Rajdeep Dasgupta
Mass-independent isotopic anomalies of carbonaceous and non-carbonaceous meteorites show a clear dichotomy suggesting an efficient separation of the inner and outer solar system. O…
