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 discovered a number of other stars.A white dwarf is 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, in conjunction with a pulsar orbiting ikduang
. White dwarf caused by Sun-like stellar collapse down to size is closest to the Earth with a very high density occurs during the end of the life expectancy of the stellar star meat consists of carbon and oxygen white dwarf almost all ye.Nalong lighting and reduced slowly
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 after star neutron spin around itself, there will be a radio beam to gush out from the two connectors when they are beamed.One of the ships, which swept the world, the radio telescope pointing on Earth, the measuring signals from neutron stars is briefly repeated
. This pulsar found named PS RJ 2222-137 as the first moon in the system that were discovered were found 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 are views.Rakiriya by gravity with a companion star which one initially expects the same neutron stars may be or may become white dwarf cooling than usual orbit astronomers calculated the period between the two object. 2.45 days longer than a continuous survey
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 companion star has been blocked by the pulsar, which resulted from 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.ต่ละดวง that the pulsar mass is 1.2 solar mass star with a mass companions section 1.05 solar mass
. This information represents an orbit too orderly the Super Nova II in the same area, which means that the companion star of pulsar PS RJ 2222-neutron stars is the same as the 137 is not just a possibility.One is a white dwarf
. 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 does not detect this white dwarf
. 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 very cool white dwarf"
. The Committee of astronomers calculated that the white dwarf is likely to have a temperature of not more than 2700 OC
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.
