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
Anharmonic oscillations of rotating stars have been studied by various authors in literature toexplain the observed features of certain variable stars. However,
We examine the validity of the ΛCDM model and probe the dynamics of dark energy with the latest astronomical observations.Using the Om(z) diagnosis,we find tha
