Researchers from China have confirmed the existence of an approximately 8.5-year Inner Core Wobble (ICW) in both polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the Earth's ...
In a new report on Science Advances, Chen Fang and Liang Fu from the Beijing National Laboratory for Condensed Matter Physics in China, Kavli Institute for Theoretical Sciences and the Department of Physics, Massachusetts ...
Using the Nanshan One-meter Wide-field Telescope (NOWT), Chinese astronomers have performed multi-color photometric observations of a rapidly rotating magnetic star known as HD 345439. Results of this observational campaign, ...
By combining transit photometry, radial velocity observations, and asteroseismology, astronomers have gathered important information about the properties of a highly eccentric, eclipsing binary system known as KOI-3890. The ...
Saturn's distinctive rings were observed in unprecedented detail by NASA's Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination ...
