Solid phase material exists in low density astrophysical environments, from stellar atmospheres to interstellar clouds, from current times to early phases of the universe. We consider the origin, composition and evolution of solid phase materials in the particular case of stellar outer atmospheres, as representative of many conditions. Also considered are the dynamics and interactions in circum...
Polarimetry has been used to detect the occurrence of configurational changes accompanying denaturation in various proteins (Jirgensons, 1950, 1951, 1952; Kauzmann el al., 1953; Yang and Foster, 1954; Linderstrf~mLang and Schellman, 1954). However, because of the present incomplete knowledge of protein structure, no concrete proposals have yet been made connecting observed rotational values and...
Our research team, Christpher Zappa (Lamont-Doherty Earth Observatory), Michael Banner (LamontDoherty Earth Observatory and University of New South Wales) and Howard Schultz (University of Massachusetts, Amherst), conducted a proof-of-concept study to assess the effectiveness of a new passive optical technique based on polarimetry. Conventional optical remote sensing techniques rely on light am...
Due to the spin-orbit interaction, the electron scattering from the nucleus is sensitive to the spin orientation of that electron. This is used for polarimetry of electron beams in the Mott method. The spin-orbit interaction was also observed in bremsstrahlung. In this article we analyze its potential for polarimetry as an alternative to the Mott method. It can simultaneously measure all three ...
We summarize the wide range of current and upcoming developments in low temperature detectors for CMB and submiUimeter astronomy. We discuss work in sensor development, photon coupling and filtering architectures, and polarimetry and how these tie to applications requirements.
