Context_1 : A dark-energy star is a hypothetical compact astrophysical object, which a minority of physicists think might constitute an alternative explanation for observations of astronomical black hole candidates. Context_2 : In planetary science a streaming instability is a hypothetical mechanism for the formation of planetesimals in which the drag felt by solid particles orbiting in a gas disk leads to their spontaneous concentration into clumps which can gravitationally collapse. Small initial clumps increase the orbital velocity of the gas, slowing radial drift locally, leading to their growth as they are joined by faster drifting isolated particles. Massive filaments form that reach densities sufficient for the gravitational collapse into planetesimals the size of large asteroids, bypassing a number of barriers to the traditional formation mechanisms. The formation of streaming instabilities requires solids that are moderately coupled to the gas and a local solid to gas ratio of one or greater. The growth of solids large enough to become moderately coupled to the gas is more likely outside the ice line and in regions with limited turbulence. An initial concentration of solids with respect to the gas is necessary to suppress turbulence sufficiently to allow the solid to gas ratio to reach greater than one at the mid-plane. A wide variety of mechanisms to selectively remove gas or to concentrate solids have been proposed. In the inner Solar System the formation of streaming instabilities requires a greater initial concentration of solids or the growth of solid beyond the size of chondrules. Context_3 : 1906 Naef, provisional designation 1972 RC, is a stony vestoid asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 5 September 1972, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland. It was later named after Swiss banker and amateur astronomer Robert Naef. Context_4 : Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship. These models have been proposed as alternatives to the models that require metric expansion of space of which the Big Bang and the Steady State cosmologies are the most famous examples. The concept was first proposed in 1929 by Fritz Zwicky, who suggested that if photons lost energy over time through collisions with other particles in a regular way, an idea not too different from Breit-Wheeler process, the more distant objects would appear redder than more nearby ones. Zwicky himself acknowledged that any sort of scattering of light would blur the images of distant objects more than what is seen. Additionally, the surface brightness of galaxies evolving with time, time dilation of cosmological sources, and a thermal spectrum of the cosmic microwave background have been observed these effects should not be present if the cosmological redshift was due to any tired light scattering mechanism. Despite periodic re-examination of the concept, tired light has not been supported by observational tests and has lately been consigned to consideration only in the fringes of astrophysics. Context_5 : Wallowa County is a county in the U.S. state of Oregon. As of the 2010 census, the population was 7,008, making it Oregon's fourth-least populous county. Its county seat is Enterprise. According to "Oregon Geographic Names", the origins of the county's name are uncertain, with the most likely explanation being it is derived from the Nez Perce term for a structure of stakes (a weir) used in fishing. An alternative explanation is that "Wallowa" is derived from a Nez Perce word for "winding water". The journals of Lewis and Clark Expedition record the name of the Wallowa River as "Wil-le-wah". Context_6 : Israelian Hebrew (or IH) is a proposed northern dialect of biblical Hebrew (BH). It is proposed as an explanation for various irregular linguistic features of the Masoretic Text (MT) of the Hebrew Bible. It competes with the alternative explanation that such features are Aramaisms, indicative either of late dates of composition, or of editorial emendations. Although IH is not a new proposal, it only started gaining ground as a challenge to older arguments to late dates for some biblical texts since about a decade before the turn of the 21st century: linguistic variation in the Hebrew Bible might be "better" explained by synchronic rather than diachronic linguistics, meaning various biblical texts could be significantly older than many 20th century scholars supposed. Context_7 : Fritz Zwicky (February 14, 1898 February 8, 1974) was a Swiss astronomer. He worked most of his life at the California Institute of Technology in the United States of America, where he made many important contributions in theoretical and observational astronomy. In 1933, Zwicky was the first to use the virial theorem to infer the existence of unseen dark matter, describing it as ""dunkle Materie "". Context_8 : 1803 Zwicky, provisional designation 1967 CA, is a stony Phocaea asteroid from the inner regions of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 6 February 1967, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland. It was later named after Swiss astronomer Fritz Zwicky. Context_9 : William G. Tifft is Emeritus Professor/Astronomer at the University of Arizona. His main interests are in galaxies, superclusters and what Tifft calls redshift problems (see redshift quantization). He was influential in the development of the first redshift surveys and was an early proponent of manned space astronomy, conducted at a proposed moon base for example. In retirement, he is a principal scientist with The Scientific Association for the Study of Time in Physics and Cosmology (SASTPC). Context_10 : NGC 1614 is the "New General Catalogue" identifier for a spiral galaxy in the equatorial constellation of Eridanus. It was discovered on December 29, 1885 by American astronomer Lewis Swift, who described it in a shorthand notation as: pretty faint, small, round, a little brighter middle. The nebula was then catalogued by Danish-Irish astronomer J. L. E. Drayer in 1888. When direct photography became available, it was noted that this galaxy displayed some conspicuous peculiarities. American astronomer Halton Arp included it in his 1966 "Atlas of Peculiar Galaxies". In 1971, Swiss astronomer Fritz Zwicky described it as a "blue post-eruptive galaxy, compact patchy core, spiral plumes, long blue jet SSW". fact_1 : Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship. fact_2 : He worked most of his life at the California Institute of Technology in the United States of America, where he made many important contributions in theoretical and observational astronomy. Question: where did the a Swiss astronomer work most of his life, who proposed a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship?
