During its commissioning and pilot phases, the Wide Field Survey Telescope stared at the galactic plane for 13 hours, leading to the discovery of a variable hot white dwarf and an ellipsoidal white dwarf binary.
New high-resolution near-infrared spectra of nine stars reveal the chemical abundance trends for more than a dozen elements, providing clues to the formation history of the Milky Way’s nuclear star cluster.
Using a normalizing flow emulator, researchers predict the gravitational wave strain distribution due to supermassive black hole binaries; this method outperforms Gaussian process methods.
The current orbit of Mars’s larger and closer-in moon, Phobos, is consistent with either formation in the early solar system and inward migration, or production in an ongoing ring–moon cycle.
High-resolution imagery, thermal observations, topographic, geological, and mineralogical analyses suggest that a previously identified cave candidate is connected to the subsurface cave environment.
Stellar-mass black holes may become ensnared in gravitational traps in the disks around accreting black holes, but simulations show how binary black holes may be able to escape or remove the traps.
