Geology of the InSight landing site on Mars
Rodriguez, S.; Forget, F.; Hauber, E. +44 more
The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft landed successfully on Mars and imaged the surface to characterize the surficial geology. Here we report on the geology and subsurface structure of the landing site to aid in situ geophysical investigations. InSight landed in a degraded impact cr…
X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
Shu, Xinwen; Jiang, Ning; Li, Shuo +8 more
Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or only weak X-ray detections in most of them. Here we report the discovery of delayed X-ray brightening around 140 days …
Phosphorus-rich stars with unusual abundances are challenging theoretical predictions
Masseron, Thomas; García-Hernández, D. A.; Zamora, Olga +4 more
Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the origin of phosphorus is of extreme interest because it is known to be essential for life such as we know on Earth. However, current models of (Galactic) chemical evolution u…
Structural insights into the mechanism of rhodopsin phosphodiesterase
Ikuta, Tatsuya; Shihoya, Wataru; Sugiura, Masahiro +9 more
Rhodopsin phosphodiesterase (Rh-PDE) is an enzyme rhodopsin belonging to a recently discovered class of microbial rhodopsins with light-dependent enzymatic activity. Rh-PDE consists of the N-terminal rhodopsin domain and C-terminal phosphodiesterase (PDE) domain, connected by 76-residue linker, and hydrolyzes both cAMP and cGMP in a light-dependen…
