Are substructures in different components of protoplanetary disks correlated?
14 1月 2022Image credit: Law et al. 2021, MAPS IIIIt is commonly believed that planets form in disks surrounding young stars, but how exactly this happens remains an outstanding question. In recent years, astronomers have made great strides in directly observing protoplanetary disks using the Atacama Large Millimeter/submillimeter Array (ALMA), located in the Atacama Desert of Northern Chile. By observing...

PolarLight Reveals the Corona Geometry in Sco X-1
10 1月 2022On 2022 January 1, Hua Feng and his collaborators reported in The Astrophysical Journal Letters a significant detection of X-ray polarization in Sco X-1 with the space mission PolarLight, which has been operating on-orbit for more than three years since its launch in 2018 October. The results help place stringent constraints on the geometry of the hot corona, and mark Sco X-1 as the second astr...
