Study reveals nature of single-line spectroscopic binary with δ Scuti pulsating star KIC 10417986

Researchers carried out the time-domain spectroscopic observation of KIC 10417986 with the Nanshan 1.2-m Optical Telescope and Xinglong 2.16-m Telescope. They obtained the orbital parameters and stellar parameters of the binary system fo...Binary systems are ideal for accurately identifying the basic physical parameters, such as mass, radius and luminosity, of the stars. In particular, pulsating variable stars are of great significance, as they offer means for detecting th...

Researchers propose RFI mitigation and signal restoration method for pulsar signals

Using pulsar data collected by the NanShan 26-m Radio Telescope (NSRT) from 2011 to 2014, researchers from the Xinjiang Astronomical Observatory (XAO) of Chinese Academy of Sciences made a study on RFI mitigation and signal restoration, ...Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing, one is the radio-frequency interference (RFI) mitigation, and the other one is information loss ...
