Anharmonic oscillations of rotating stars have been studied by various authors in literature toexplain the observed features of certain variable stars. However,
The Five-hundred-meter Aperture Spherical radio Telescope(FAST) will become one of the world-leading telescopes for pulsar timing array(PTA) research. The prima
We present the database of maser sources in H2 O,OH and Si O lines that can be used to identify and study variable stars at evolved stages.Detecting the maser e
About 786.4 thousand stars were observed by LAMOST twice or more during the first stage of its spectroscopic survey. The radial velocity differences for about 2
The Full-disk Magneto Graph(FMG),a payload onboard the Advanced Space Solar Observatory(ASO-S),will measure the vector magnetic field in the photosphere.The ins
