Cosmochemical evidence for the existence of short-lived radioisotopes (SLRI) such as $^{26}$Al and $^{60}$Fe at the time of the formation of primitive meteorites requires that these isotopes were synthesized in a massive star and then incorporated in

The scenario of the triggered origin of the solar system suggests that the formation of our planetary system was initiated by the impact of an interstellar shock wave on a molecular cloud core. The strength of this scenario lies in its ability to exp

Results from numerical simulations of shock waves impacting molecular cloud cores are presented. The three-dimensional smoothed particle hydrodynamics code used in the calculations includes effects from a varying adiabatic exponent, molecular, atomic
The discovery of decay products of a short-lived radioisotope (SLRI) in the Allende meteorite led to the hypothesis that a supernova shock wave transported freshly synthesized SLRI to the presolar dense cloud core, triggered its self-gravitational co

Certain meteoritical inclusions contain evidence for the existence of short-lived radioactivities such as 26A1 and 41Ca at the time of their formation 4.566 billion years ago. Because the half-lives of these nuclides are so short, this evidence requi
