Richard Alfred Rossiter
Richard Alfred Rossiter (December 19, 1886 January 26, 1977) was an American astronomer, known for the Rossiter–McLaughlin effect. Rossiter served as director of the Lamont–Hussey Observatory from 1928 until 1952. Early life Rossiter was born in Oswego, New York, on December 19, 1886. He graduated from Wesleyan University in 1914, and married Jane van Dusen in 1915. He taught mathematics at Wesleyan Seminary for five years before enrolling in the astronomy program at the University of Michigan. He earned a master's degree in 1920, and a doctorate three years later. His doctoral dissertation, a study of the spectrum of Beta Lyrae, demonstrated that the shift that it exhibited could be accounted for by stellar rotation. Rossiter and his wife had two children, Laura and Alfred. Career Rossiter became the first director of the Lamont–Hussey Observatory in 1928. During this tenure at the observatory, he discovered more than 5,000 double stars. His ''Catalogue of Southern Doub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oswego, New York
Oswego () is a city in Oswego County, New York, United States. The population was 16,921 at the 2020 census. Oswego is located on Lake Ontario in Upstate New York, about 35 miles (55km) northwest of Syracuse. It promotes itself as "The Port City of Central New York." It is the county seat of Oswego County. The city of Oswego is bordered by the towns of Oswego, Minetto, and Scriba to the west, south, and east, respectively, and by Lake Ontario to the north. Oswego Speedway is a nationally known automobile racing facility. The State University of New York at Oswego is located just outside the city on Lake Ontario. History Early history The British established a trading post in the area in 1722 and fortified it with a log palisade later called Fort Oswego, named after the native Iroquois place name "os-we-go" meaning "pouring out place." The first fortification on the site of the current Fort Ontario was built by the British in 1755 and called the "Fort of the Six Nations." ...

Spectral Shift
In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and simultaneous increase in frequency and energy, is known as a negative redshift, or blueshift. The terms derive from the colours red and blue which form the extremes of the visible light spectrum. In astronomy and cosmology, the three main causes of electromagnetic redshift are # The radiation travels between objects which are moving apart (" relativistic" redshift, an example of the relativistic Doppler effect) #The radiation travels towards an object in a weaker gravitational potential, i.e. towards an object in less strongly curved (flatter) spacetime (gravitational redshift) #The radiation travels through expanding space (cosmological redshift). The observation that all sufficiently distant light sources show redshift corresponding to their distance from Earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wesleyan University Alumni
Wesleyan theology, otherwise known as Wesleyan– Arminian theology, or Methodist theology, is a theological tradition in Protestant Christianity based upon the ministry of the 18th-century evangelical reformer brothers John Wesley and Charles Wesley. More broadly it refers to the theological system inferred from the various sermons (e.g. the Forty-four Sermons), theological treatises, letters, journals, diaries, hymns, and other spiritual writings of the Wesleys and their contemporary coadjutors such as John William Fletcher. In 1736, the Wesley brothers travelled to the Georgia colony in America as Christian missionaries; they left rather disheartened at what they saw. Both of them subsequently had "religious experiences", especially John in 1738, being greatly influenced by the Moravian Christians. They began to organize a renewal movement within the Church of England to focus on personal faith and holiness. John Wesley took Protestant churches to task over the nature of s ...

People From Oswego, New York
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Natal Province
The Province of Natal (), commonly called Natal, was a province of South Africa from May 1910 until May 1994. Its capital was Pietermaritzburg. During this period rural areas inhabited by the black African population of Natal were organized into the bantustan of KwaZulu, which was progressively separated from the province, becoming partially autonomous in 1981. Of the white population, the majority were English-speaking people of British descent, causing Natal to become the only province to vote "No" to the creation of a republic in the referendum of 1960, due to very strong monarchist, pro-British Commonwealth, and anti-secessionist sentiment. In the latter part of the 1980s, Natal was in a state of violence between the Inkatha Freedom Party and the African National Congress, with violence subsidising soon after the first non-racial election in 1994.Taylor, Rupert.

Stellar Rotation
Stellar rotation is the angular motion of a star about its axis. The rate of rotation can be measured from the spectrum of the star, or by timing the movements of active features on the surface. The rotation of a star produces an equatorial bulge due to centrifugal force. As stars are not solid bodies, they can also undergo differential rotation. Thus the equator of the star can rotate at a different angular velocity than the higher latitudes. These differences in the rate of rotation within a star may have a significant role in the generation of a stellar magnetic field. The magnetic field of a star interacts with the stellar wind. As the wind moves away from the star its rate of angular velocity slows. The magnetic field of the star interacts with the wind, which applies a drag to the stellar rotation. As a result, angular momentum is transferred from the star to the wind, and over time this gradually slows the star's rate of rotation. Measurement Unless a star is being observ ...

Beta Lyrae
Beta Lyrae (β Lyrae, abbreviated Beta Lyr, β Lyr) officially named Sheliak (Arabic: الشلياق, Romanization: ash-Shiliyāq) (IPA: ), the traditional name of the system, is a multiple star system in the constellation of Lyra. Based on parallax measurements obtained during the Hipparcos mission, it is approximately distant from the Sun. Although it appears as a single point of light to the naked eye, it actually consists of six components of apparent magnitude 14.3 or brighter. The brightest component, designated Beta Lyrae A, is itself a triple star system, consisting of an eclipsing binary pair (Aa) and a single star (Ab). The binary pair's two components are designated Beta Lyrae Aa1 and Aa2. The additional five components, designated Beta Lyrae B, C, D, E, and F, are currently considered to be single stars. Nomenclature ''β Lyrae'' ( Latinised to ''Beta Lyrae'') is the system's Bayer designation, established by Johann Bayer in his ''Uranometria'' of 1603, an ...
