We studied a previously reported sample of 166 planet candidates around main-sequence A-type stars in the Kepler field. We selected six of them for which we obtained extensive long-term radial velocity measurements with the Alfred-Jensch 2-m telescope in Tautenburg and the Perek 2-m telescope...
Countless tracks are interlaced in the universe where planets come across every day, but they never encounter each other. Workers in the streamline factory revolve their days and nights between the factory and the urban village endlessly, as if they were orbiting planets.Yang, Ming...
The sequence of the planets in the solar system is from the Sun, Mercury, Venus, the Earth, Mars, Jupiter to Saturn. The Sun can be treated as yang, king, father, bright, heaven, or sky. Saturn can be treated as yin, queen, mother, dark, hell, or ground. Five planets, Jupiter,...
Previous work by Tanaka (1990) determined a two-stage sequence of faulting in the area, with an initial NE and then N-S oriented extensional events. 1.3.2 Tractus Fossae The Tractus Fossae region is located immediately to the east of Ceraunius Fossae, and constitutes a unit mapped by ...
The seven planets have long been associated with the seven known metals; Gold, Silver, Iron, Mercury, Tin, Copper, and Lead. Shown in blue, they are arranged in sequence by atomic number. Start with iron(Mars) on the top right with the atomic number of 26 and follow the blue arrows....
Galaxy: Open Clusters and Associations: Individual: Name: HyadesStars: Planetary Systems: GeneralTechniques: Radial VelocitiesWe describe a high-precision radial velocity search for jovian-mass companions to main sequence stars in the Hyades star cluster. The Hyades provides an extremely well controlled...
The name “KiK-net” refers to the strong motion network planned under the fundamental survey and observation for earthquake research because the Japanese word “kiban” means fundamental. K-NET began operations in June 1996, just one and half years after the 1995 Kobe earthquake. The network ...

UY Scuti is probably the biggest known star. It is first cataloged in 1860, by German astronomers at the Bonn Observatory. In the summer of 2012, astronomers using AMBER interferometry from the Very Large Telescope (VLT) in theAtacama Desertin Chile measured the parameters of three red super...
