Abstract EN
We consider the short-lived radionuclide (SLR) 36Cl in calcium-aluminum-rich inclusions (CAIs) found in primitive meteorites with the solar wind implantation model.
In this model, SLRs are produced via nuclear reaction with solar energetic particles (SEPs) interacting with gaseous targets in the protosolar atmosphere in T-Tauri stars.
These SLRs are captured by the solar wind and then implanted in CAI precursor materials, which have dropped from the funnel flow leading onto the protostar.
This method of incorporating SLRs into solar system materials is currently active in our solar system and has been measured with SLRs from the solar wind being implanted on the lunar surface.
T-Tauri stars are capable of SEP fluxes ~105 greater than contemporary SEP fluxes.
Here we scale the production rate of 36Cl to the ancient SEP activity.
From the enhanced production rates and the refractory mass inflow rate at 0.06 AU from the protosun, we model the ancient 36Cl content in CAIs.
We find the initial isotopic ratio of 36Cl/35Cl to range from about 1 × 10−5 to 5 × 10−5 and the concentration of 36Cl to range from about 3 × 1013 to 1.5 × 1014 atoms g−1.
