Bridging the Gap between Luminous Red Novae and Common Envelope Evolution
17 4月 2024Luminous red novae (LRNe) and common envelope evolution (CEE) are closely related astrophysical phenomena and evolutionary processes that are not well understood. Among them, CEE is a crucial stage in binary stellar evolution. Close compact binaries, Type Ia supernovae, hot sub-dwarfs, and gravitational wave sources may all be the product of CEE. On the other hand, LRNe are bright transients wi...

Accreting Planets Leave Chemical Footprints in Protoplanetary Disks
28 8月 2023Protoplanetary disks serve as the cradles of planet formation, often revealing captivating features such as bright rings and dark gaps in both dust continuum and gas emission maps. These features have traditionally been attributed planets, which shape the disk by gap-opening and altering its rotation profiles, effects that can potentially be observed.A new study led by Tsinghua Department of As...
