Using the Canada-France-Hawaii Telescope (CFHT), astronomers have observed a chemically peculiar star known as HD 213258. In result, they found that HD 213258 is a rapidly oscillating, strongly magnetic Ap star. The finding ...
Drawing on the research idea of electron spin degree of freedom, the valley degree of freedom can be used as an information carrier to design and realize related functional devices. Monolayer group VI transition metal dichalcogenides ...

Using the Nanshan One-meter Wide-field Telescope (NOWT), Chinese astronomers have performed multi-color photometric observations of a rapidly rotating magnetic star known as HD 345439. Results of this observational campaign, ...
Venus, often called Earth's "evil twin" planet, formed closer to the sun and has since evolved quite differently from our own planet. It has a "runaway" greenhouse effect (meaning heat is completely trapped), a thick carbon-dioxide-rich ...
