Researchers demodulate the amplitude modulation signal of the Delta Scuti Star

Resaerchers developed a method using the Hilbert transform to separate the amplitude modulation signals of pulsating variable stars. Using Delta Scuti Star (δ Scuti star) KIC 10407873 as a case study, the researchers provided detailed p...Recently, WANG Haozhi, a PhD student from the Xinjiang Astronomical Observatory (XAO), Chinese Academy of Sciences (CAS), under the guidance of Prof. Ali Esamdin, along with their collaborators developed a method using the Hilbert transf...

Coevolution of Giant Molecular Cloud, Filaments and Clumps in relation to dense gas mass fraction

They selected 27 relatively isolated giant molecular clouds based on the CO data from the SEDIGISM survey (Schuller et al. 2017) and the COHRS survey (Dempsey et al. 2013) of the Milky Way. They used the dense gas mass fraction (DGMF) of...A research team led by Prof. ZHOU Jianjun, Prof. Jarken Esimbek and PhD student ZHANG Wenjun from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, together with their collaborators, selected 27 relatively isolate...

Researchers investigate metal pollution in white dwarf star atmospheres

Researchers conducted a numerical study on the tidal disruption of a planet surrounding a white dwarf and relevant accretion processes. Their work has constrained the structural evolution characteristics of planets during certain disrupt...Approximately 25-50% of white dwarfs have been found to exhibit metal pollution. It is commonly believed that the tidal disruption of planets surrounding a white dwarf may lead to the contamination of its atmosphere with metals. The prox...
