Struve 2398
Struve 2398 (Gliese 725) is a binary star system in the northern constellation of Draco. Struve 2398 is star number 2398 in the Struve Double Star Catalog of Baltic-German astronomer Friedrich Georg Wilhelm von Struve. The astronomer's surname, and hence the star identifier, is sometimes indicated by a Greek sigma, Σ; hence, this system can be listed with the identifier Σ 2398. Although the components are too faint to be viewed with the naked eye, this star system is among the closest to the Sun. Parallax measurements by the Gaia spacecraft give them an estimated distance of away. Both stars are small red dwarfs, with each having around a third the Sun's mass and radius. They each display the type of variability common to flare stars, and their active surfaces are sources of X-ray emission. They are orbiting with period of about 295 years, at a separation of about 56 astronomical units with an orbital eccentricity (ovalness) of 0.70. The pair has a relat ...

Struve 1341
HD 80606 and HD 80607 are two stars comprising a binary star system. They are approximately 217 light-years away in the constellation of Ursa Major. Both stars orbit each other at an average distance of 1,200 astronomical units. The binary system is listed as Σ1341 in the Struve Catalogue of Double Stars; however, this designation is not in wide use and the system is usually referred to by the HD designations of its constituent stars. An extrasolar planet has been confirmed to orbit HD 80606 in a highly elliptical orbit. Planetary system The variable radial velocity of HD 80606 was first noticed in 1999 from observations with the 10-m Keck 1 telescope at the W. M. Keck Observatory in Hawaii by the G-Dwarf Planet Search, a survey of nearly 1,000 nearby G dwarfs to identify extrasolar planet candidates. The star was then followed up by the Geneva Extrasolar Planet Search team using the ELODIE spectrograph mounted on the 1.93-m telescope at the Haute-Provence Observatory ...

Struve Double Star Catalog
Friedrich Georg Wilhelm von Struve (russian: link=no, Василий Яковлевич Струве, trans. ''Vasily Yakovlevich Struve''; 15 April 1793 – ) was a Baltic German astronomer and geodesist from the famous Struve family. He is best known for studying double stars and for initiating a triangulation survey later named Struve Geodetic Arc in his honor. Life He was born at Altona, Duchy of Holstein (then a part of the Denmark–Norway kingdoms), the son of Jacob Struve (1755–1841). Struve's father moved the family away from the French occupation to Dorpat (Tartu) in Estonia (then part of the Russian Empire) to avoid military service,V. K.

Otto Struve Telescope
The Otto Struve Telescope was the first major telescope to be built at McDonald Observatory. Located in the Davis Mountains in West Texas, the Otto Struve Telescope was designed by Warner & Swasey Company and constructed between 1933 and 1939 by the Paterson-Leitch Company. Its mirror was the second largest in the world at the time. It was named after the Russian-American astronomer Otto Struve in 1966, three years after his death; Struve had been the director of McDonald Observatory from 1932–1950. The Davis Mountains is an excellent location for astronomical research because of the clear dry air and moderately high elevation. The remote nature of the facility proved to be a significant challenge in transporting such a large mirror. It was a very precarious journey for the Otto Struve Telescope's mirror to this remote part of Texas and up to the top of Mount Locke. The mirror was transported from the local town of Fort Davis up the mountain by Carleton D. Wilson, owner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Struve Geodetic Arc
The Struve Geodetic Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through ten countries and over , which yielded the first accurate measurement of a meridian arc. The chain was established and used by the German-born Russian scientist Friedrich Georg Wilhelm von Struve in the years 1816 to 1855 to establish the exact size and shape of the earth. At that time, the chain passed merely through three countries: Norway, Sweden and the Russian Empire. The Arc's first point is located in Tartu Observatory in Estonia, where Struve conducted much of his research. Measurement of the triangulation chain comprises 258 main triangles and 265 geodetic vertices. The northernmost point is located near Hammerfest in Norway and the southernmost point near the Black Sea in Ukraine. In 2005, the chain was inscribed on the World Heritage List, because of its importance in geodesy and its testimony to international scientific cooperation. The W ...

Struve Function
In mathematics, the Struve functions , are solutions of the non-homogeneous Bessel's differential equation: : x^2 \frac + x \frac + \left (x^2 - \alpha^2 \right )y = \frac introduced by . The complex number α is the order of the Struve function, and is often an integer. And further defined its second-kind version \mathbf_\alpha(x) as \mathbf_\alpha(x)=\mathbf_\alpha(x)-Y_\alpha(x). The modified Struve functions are equal to , are solutions of the non-homogeneous Bessel's differential equation: : x^2 \frac + x \frac - \left (x^2 + \alpha^2 \right )y = \frac And further defined its second-kind version \mathbf_\alpha(x) as \mathbf_\alpha(x)=\mathbf_\alpha(x)-I_\alpha(x). Definitions Since this is a non-homogeneous equation, solutions can be constructed from a single particular solution by adding the solutions of the homogeneous problem. In this case, the homogeneous solutions are the Bessel functions, and the particular solution may be chosen as the corresponding Struve fun ...

Struve (crater)
Struve is the lava-flooded remains of a lunar impact crater. It is located near the western extreme of the Oceanus Procellarum, close to the western lunar limb. As a consequence, even though it is roughly circular in outline, it appears oval due to foreshortening. The northern rim of this crater intersects the smaller lava-flooded crater Russell to the north, and there is now a wide gap between the two formations. Attached to the southeast rim is the remains of another lava-flooded formation, Eddington. Farther to the southwest is Balboa, near the lunar limb. The rim of Struve is heavily worn and irregular, with several gaps connecting to the surrounding mare. It resembles little more than a circular mountain range, climbing to a maximum height of 1.7 km. There are several small impact craters within the wall, most notably in the southeast part of the crater. The crater Struve G overlaps the inner part of the western rim, and just to the north of this crater is a gap in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2227 Otto Struve
2227 Otto Struve, provisional designation , is an asteroid from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter. The asteroid was discovered on 13 September 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. It was named after Russian astronomer Otto Struve. Orbit and classification The asteroid orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,222 days). Its orbit has an eccentricity of 0.17 and an inclination of 5 ° with respect to the ecliptic. It was first identified as at the Johannesburg Observatory in 1935, extending the body's observation arc by 20 years prior to its official discovery observation.

Stefan Struve
Stefan Jaimy Struve (; born February 18, 1988) is a Dutch former mixed martial artist who competed as a heavyweight in the Ultimate Fighting Championship (UFC). At , he is the tallest fighter in the history of the UFC. Background Growing up in the Netherlands, Struve played football until the age of 14. When Struve's brother took him to the local martial arts gym (owned by Bob Schreiber), he decided to pursue a career in mixed martial arts (MMA) instead. Struve had his first and only amateur MMA bout at age 16 and won via head kick knockout. Mixed martial arts career Struve made his professional debut for the GFN organization when he was 17, fighting John De Wilde at ''Gentlemen Fight Night''. By late 2008, he had racked up a record of 16–2, losing once (in his second fight) via injury to Romualds Garkulis and again in the second round of a ''Star Of Peresvit'' tournament in Ukraine, to future Bellator Light heavyweight Champion Christian M'Pumbu.
