This cooperative agreement was established with the scientific goal of understanding the conditions of early solar-type planetary systems. We investigated two facets of young solar systems: The effects on planetary bodies of young solar-type stellar mass loss, and photo-production of various organic materials due to radiation under comet-like conditions
Circumstellar disks have long been regarded as windows into planetary systems. The advent of high se...
The relatively warm temperatures required on early Earth and Mars have been difficult to account for...
We present the discovery of debris systems around three solar mass stars based upon observations per...
A moderately massive early Sun has been proposed to resolve the so-called faint early Sun paradox. W...
Recently developed solutions of problems are discussed that were traditionally considered fundamenta...
Topics addressed include: interstellar chemistry and primitive bodies; astronomical measurements and...
Global mean temperatures near 273 K on early Mars are difficult to explain in the context of standar...
Observations indicate that the Earth was at least warm enough for liquid water to exist as far back ...
The early solar system represents the only case we have of a circumstellar disk that can be investig...
The origin and evolution of the solar system are analyzed. Physical processes are first discussed, f...
We report the results of deep observations at radio (3.6 cm) wavelengths of the nearby solar‐type st...
