This chapter surveys the diversity of objects orbiting our Sun and what they tell us about the origins and evolution of the solar system. The numerous small bodies populating specific orbits, from the asteroid belt to the far reaches of the Oort cloud, encode information on the solar system’s age and the initial conditions in the solar nebula. The surfaces and atmospheres of the planets and their satellites reveal how the same fundamental physical processes produced bodies with vastly different characteristics, from the dry, metal-dominated composition of Mercury through the storm-wracked hydrogen atmosphere of Jupiter. Finally, the search for liquid water and temperate climates elsewhere in the solar system, past or present, provides context for understanding the origin of life on Earth and the potential for life’s existence elsewhere in the Universe.", } @book_section {CaltechAUTHORS_https://authors.library.caltech.edu/id/eprint/94949, title ="Observational Constraints on the Distribution and Temperature Dependence of H_2O_2 on the Surface of Europa", author = "Trumbo, S.

From surface and subsurface, to atmospheres (including deep atmospheres of the giant planets), to rings, to the magnetosphere of Jupiter, these observations provide unique information on the current state, and sometimes history, of the bodies. The ngVLA will enable the highest sensitivity and resolution observations of this kind, with the potential to revolutionize our understanding of some of these bodies. In this article, we present a review of state-of-the-art radio wavelength observations of a variety of bodies in our solar system, varying in size from ring particles and small near-Earth asteroids to the giant planets. Throughout the review we mention improvements for each body (or class of bodies) to be expected with the ngVLA. A simulation of a Neptune-sized object is presented in Section 6. Section 7 provides a brief summary for each type of object, together with the type of measurements needed for all objects throughout the Solar System.", } @book_section {CaltechAUTHORS_https://authors.library.caltech.edu/id/eprint/94941, title ="Fizeau interferometric imaging of Io volcanism with LBTI/LMIRcam", author = "Leisenring, J.

Coherent combination of these two AO-corrected apertures via the LBT Interferometer (LBTI) produces Fizeau interferometric images with a spatial resolution equivalent to that of a 22.8-meter telescope and the light- gathering power of single 11.8-meter mirror. Capitalizing on these unique capabilities, we used LBTI/LMIRcam to image thermal radiation from volcanic activity on the surface of Io at M-Band (4.8 μm) over a range of parallactic angles. At the distance of Io, the M-Band resolution of the interferometric baseline corresponds to a physical distance of ~135 km, enabling high-resolution monitoring of Io volcanism such as ares and outbursts inaccessible from other ground-based telescopes operating in this wavelength regime. Two deconvolution routines are used to recover the full spatial resolution of the combined images, resolving at least sixteen known volcanic hot spots. Coupling these observations with advanced image reconstruction algorithms demonstrates the versatility of Fizeau interferometry and realizes the LBT as the first in a series of extremely large telescopes.", } @book_section {CaltechAUTHORS_https://authors.library.caltech.edu/id/eprint/94938, title ="OH emission and absorption associated with supernovae in Arp 220", author = "Lonsdale, Colin J. and de Kleer, Katherine R.", journal = "Proceedings of the International Astronomical Union", number = "242", pages = "432-436", month = "March", year = "2007", doi = "10.1017/s1743921307013555", issn = "1743-9213", isbn = "9780521874649", url = "https://resolver.caltech.edu/CaltechAUTHORS:20190424-141802700", note = "© International Astronomical Union 2008. \n\nCJL acknowledges support from NSF grant AST-0352953 to the MIT Haystack Observatory.

This galaxy hosts a powerful starburst, with an associated supernova (SN) rate of order 4/yr. An extensive population of compact continuum sources interpreted as radio supernovae (RSNe) and young supernova remnants (SNR) has been imaged. We show here that many of the supernova-related radio continuum point sources exhibit clear evidence of OH absorption or maser emission in the intervening gas, and as such provide us with a sampling of conditions along very narrow and specific lines of sight through the nuclear environment. The OH gas along these lines of sight exhibits velocity dispersions of up to several tens of km/sec, and that in some cases, multiple distinct concentrations of masing gas at different radial velocities can be discerned. There is evidence for variability in the OH properties on ~1yr timescales. Our results are discussed in the context of the overall OH megamaser properties of Arp 220.", }
