Using Cometary Activity to Trace the Physical and Chemical Evolution of Cometary Nuclei
Historically, minor bodies are classified as comets based on observations of “activity,” which refers to the appearance of dust and gas around the nucleus. While cometary activity has been observed for centuries, at ever-increasing heliocentric distances, our understanding of the mechanisms for producing cometary activity and its heliocentric dependence has only recently been developed to the l...
متن کاملPhysical and Functional Aspects of Boshrūyeh Mills
Water can be considered to be the reason for existence and the main factor in formation of some of the traditional Iranian architectural structures. Innovative technologies such as [water] mills and water reservoirs etc. can be placed in this category. These structures are the result of the interaction of the previous generations with nature and utilising its various elements. The human of the ...

متن کاملCometary Dust in the Debris Disks of Hd 31648 and Hd 163296: Two " Baby " Β Pics
The debris disks surrounding the pre-main sequence stars HD 31648 and HD 163296 were observed spectroscopically between 3 and 14 μm. Both possess a silicate emission feature at 10 μm which resembles that of the star β Pictori and those observed in solar system comets. The structure of the band is consistent with a mixture of olivine and pyroxene material, plus an underlying continuum of unspeci...
متن کاملCometary Origin of the Zodiacal Cloud and Carbonaceous Micrometeorites. Implications for Hot Debris Disks
The zodiacal cloud is a thick circumsolar disk of small debris particles produced by asteroid collisions and comets. Their relative contribution and how particles of different sizes dynamically evolve to produce the observed phenomena of light scattering, thermal emission, and meteoroid impacts are unknown. Until now, zodiacal cloud models have been phenomenological in nature, composed of ad ho...
