One of the Committee of astronomers, led by David from the University of Wisconsin and a thriving Cape-Milwaukee the Green telescope were nabaeng of the National Radio Observatory and the u.s. network's tradition is combined with the camera (b) Astronomical Observatory are a number of other. Find star white dwarf is probably the most cool and fade ever discovered. White dwarf in this age of approximately 11 billion a year, or equal to the entire Milky Way Galaxy, is a white dwarf star in a double system, together with one of the ikduang orbit pulsar. White dwarf caused by Sun-like stellar collapse down to size is closest to Earth. There is a very high density. Occurs during the end of the stellar life expectancy Carbon and oxygen stars consists of meat, almost all. Cool white dwarf and slowly reduced lighting The neutron stars is a pulsar rotating around itself with high-velocity stellar remains that same life expectancy, but due to a high-mass star. When neutron stars rotate around itself, there will be a radio beam to gush out of both polarities. When a beam is a beam pointing to sweep the world. Radio telescope on Earth, the measuring signal from neutron stars is briefly duplicated. This pulsar found named PS RJ 2222-137 as the first moon in the system that have been discovered. Discovered by using the Green telescope nabaeng Polls initially showed that this pulsar rotates around itself, with a rate of 30 rounds per second, and found that there is interaction and gravity with one companion star. In a preliminary estimate that it might be the same neutron star or white dwarf may be cooler than normal. Astronomers calculate an orbit between two objects. 2.45. From the survey continued for more than two years by network DVD LG b-cause I know this world away from the pulsar 900 light-year in the position of someone carrying a water pot. From a study of Pulsar radio signals from the delay that occurs while the pulsar was blocked by the companion star. As a result of the distortion of the spatial-time companion stars that make Astronomers measure the direction and angle of the orbit, including the mass of the star each moon that has mass 1.2 solar mass pulsar. Best solar mass stars, there are 1.05-mass companions. This information represents an orbit too orderly the Super Nova II in the same area. This means that the companion star of pulsar PS RJ 2222-137 is not the same neutron star. The only possibility is a white dwarf star. However, a survey in the white light a wheel lifting ngosa (SOAR--Southern Astrophysical Research) in Chile and a 10-meter telescope in Hawaii khek back this white dwarf was not detected. The bar was pushed lab from the University of North Carolina at Chapel Hill explains that "If the white dwarf companion star is a reality, it must be a white dwarf that is very cool," he said. The Committee of astronomers calculated that the white dwarf is likely to have a temperature of not more than 2700° c. A cool white dwarf is expected this level seems to have most of the elements are carbon crystals like diamonds. In theory, this category is likely to star considerably but with very low lighting that is so difficult to detect. In this case, fortunately, that white dwarf stars in this romantic couple makes astronomers have detected.
