Research Ucovers Long-Term Pulsation Evolution in the δ Scuti Variable Star KIC 8712760

The researchers conducted a long-term observational study on the δ Scuti variable star KIC 8712760. Their work revealed a significant evolution of the star's pulsation amplitude over time. Stars are not eternally quiet and unchanging celestial bodies; some stars periodically brighten and dim. Astronomers refer to this phenomenon as stellar pulsation. Studying these pulsations is like performing an "ultrasound examination" ...

How do the ultra-long period radio pulsars differ from normal pulsars?

The resaerchers investigate the emission properties in 10 ULRa-TPs against that of 100 FAST normal pulsars based on their emission geometry and several emission correlations well-known to radio pulsars.We ask the question: To what extent do ultra‑long period radio pulsars and transients (ULRa-TPs) differ from conventional radio pulsars? It is apparent that they rotate very slowly, but do they also behave differently in the emission ph...

A Rapid Spin-down Millisecond Pulsar Puts Stringent Constraints on Classical Theory of Millisecond Pulsar Formation

The researchers conducted deep observations of the newly discovered millisecond pulsar PSR J0435+3233 with abnormally high spin-down rate.A research team led by Prof. WANG Na from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) conducted in-depth observations of PSR J0435+3233 using the Five-hundred-meter Aperture Spherical radio Telesc...

Researchers Discover Direct Observational Evidence for Chromospheric Magnetic Reconnection Driving Quasiperiodic Coronal Jets

The researchers use high spatiotemporal resolution observations from space (SDO) and ground-based (NVST) telescopes to discover direct observational evidence for the quasiperiodic magnetic reconnection driving mechanism of coronal jets. Solar jets are common transient plasma ejection phenomena in the solar atmosphere, observable in multiple wavebands such as Hα, extreme ultraviolet (EUV), and X-ray. But coronal jets continuously transport mass and energy from the lower...

Unveiling the Long-Term Evolution of Magnetar Swift J1834.9-0846

The researchers developed a unified evolutionary model that simultaneously incorporates magnetic dipole radiation, wind braking, and gravitational-wave emission, and provided a new explanation for its unusually low braking index. Recently, LI Biaopeng, a PhD student supervised by Prof. GAO Zhifu in the Pulsar Research Group at Xinjiang Astronomical Observatory, Chinese Academy of Sciences, carried out a study on the unusual spin-down behavior of the magnetar Swif...
