The production of short-lived radionuclides by new non-rotating and rotating Wolf-Rayet model stars [PDF]
, 2006 It has been speculated that WR winds may have contaminated the forming solar system, in particular with short-lived radionuclides (half-lives in the approximate 10^5 - 10^8 y range) that are responsible for a class of isotopic anomalies found in some meteoritic materials.

Interaction of Supernova Ejecta with Nearby Protoplanetary Disks [PDF]
Astrophys.J.662:1268-1281,2007, 2007 The early Solar System contained short-lived radionuclides such as 60Fe (t1/2 = 1.5 Myr) whose most likely source was a nearby supernova. Previous models of Solar System formation considered a supernova shock that triggered the collapse of the Sun's nascent molecular cloud.

The challenge of detecting remote spectroscopic signatures from radionuclides [PDF]
ApJ (2024) 973: 161The characterization of exoplanetary atmospheres through transit spectra is becoming increasingly feasible, and technology for direct detection remains ongoing. The possibility of detecting spectral features could enable quantitative constraints on atmospheric composition or even serve as a potential biosignature, with the sensitivity of the instrument

The birth environment of the solar system constrained by the relative abundances of the solar radionuclides [PDF]
, 2019 The relative abundances of the radionuclides in the solar system at the time of its birth are crucial arbiters for competing hypotheses regarding the birth environment of the Sun. The presence of short-lived radionuclides, as evidenced by their decay products in meteorites, has been used to suggest that particular, sometimes exotic, stellar sources ...
