Spectroscopic Confirmation of Contact Binary Candidates Enabled by Multi‑Survey Data

The researchers have developed a new method for identifying contact binary candidates based on photometric periods, stellar radii, and radial velocity variations. By combining high-precision photometric data from the Transiting Exoplanet...A research team led by Ph.D. student WU Ting, together with her supervisor prof. LIU Jinzhongfrom Xinjiang Astronomical Observatory and Prof. GU Weimin from Xiamen University, has developed a new method for identifying contact binary can...

A Gaze Through the Dust: A Hidden Black Hole Uncovered in a Rare Triple-Galaxy Collision

A study published in the Astronomy & Astrophysics reveals that deep within the northern nucleus of this complex system lurks a supermassive black hole steadily accreting matter from its surroundings. Galaxy mergers are among the most spectacular and destructive events in the Universe. During these encounters, not only billions of stars are redistributed, but the supermassive black holes lurking in the galaxies' centers can also inter...

How Do Massive Stars Keep Growing? Thermal Feedback May Be the Key

The researchers investigated how massive protostars heat their surrounding material using data from the ALMA-QUARKS survey. The study found that intense radiation from protostars can suppress further fragmentation of the surrounding hot ...Massive stars form within cold, dense molecular clouds. As gas contracts under gravity, it can readily fragment into many smaller cores. A longstanding question in astronomy is thereforehow massive stars avoid excessive fragmentation of ...

A New Finding Reveals New Clues to Pulsar Interior–Magnetosphere Coupling

By analyzing the long-term timing data obtained with the Nanshan 25 m radio telescope from 2002 to 2014 and the publicly available international datasets, a research team from the Xinjiang Astronomical Observatory, Chinese Academy of Sci...Pulsars are rapidly rotating neutron stars with exceptionally stable spin rates, making them veritable "cosmic clocks" in the universe. However, some pulsars undergo sudden "glitches"—abrupt spin-up events followed by a gradual recovery...

A Fossil Bubble in the Milky Way Reveals a Relay of Star Formation

The researchers conducted a study on G35.28+0.04, a giant ring-like molecular gas structure in the Milky Way. They found that this structure may record a "relay race" of star formation that has lasted for tens of millions of years. The r...Massive stars play a key role in the interstellar medium cycle, molecular cloud evolution, and star formation. Through ultraviolet radiation, stellar winds, and even supernova explosions, massive stars continuously influence the surround...
