Comets and the early solar system
© 2008 American Institute of Physics, S-0031-9228-0806-010-9 Active comets are fascinating ephemeral bodies that have both thrilled and terrified people for millennia. As a bonus, when Earth passes through a comet’s debris trail, we see a dazzling meteor shower. The phenomena of comets are spectacular, but what they can tell us about the early solar system is extraordinary. Comets are the best-...
متن کاملObservations of molecules in comets
Comets are among the most primitive bodies of the Solar System, and their chemical composition is rich in information on the protosolar nebula and its possible connection with interstellar cloud chemistry. Comets are also a source of light atoms and probably of prebiotic organic molecules for the early Earth. We know better and better cometary volatiles through spectroscopy, mainly at infrared ...
متن کاملThe Main Belt Comets and ice in the Solar System
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, mod...
متن کاملThe Solar–Stellar Connection
The discovery that radio emission from stars is quite common and readily detectable was one of the unexpected advances produced by the Very Large Array [35,11]. This discovery could not be predicted based on what we know of the Sun’s radio emission, even though similar physical mechanisms are operating in stellar radio sources and so knowledge of the Sun’s emission is essential for understandin...
متن کاملA Bima Array Survey of Molecules in Comets
We present an interferometric search for large molecules, including methanol (CH3OH), methyl cyanide (CH3CN), ethyl cyanide (CH3CH2CN), ethanol (CH3CH2OH), and methyl formate (CH3OCHO), in comets LINEAR (C/2002 T7) and NEAT (C/2001 Q4) with the Berkeley-Illinois-Maryland Association NASA Goddard Space Flight Center, Computational and Information Sciences and Technologies Office, Code 606, Green...
