Detectability of satellites around directly imaged exoplanets and brown dwarfs [PDF]

, 2022
Satellites around substellar companions are a heterogeneous class of objects with a variety of different formation histories. Focusing on potentially detectable satellites around exoplanets and brown dwarfs, we might expect to find objects belonging to two main populations: planet-like satellites similar to Titan or the Galileian Satellites - likely ...

V1298 Tau with TESS: Updated Ephemerides, Radii, and Period Constraints from a Second Transit of V1298 Tau e [PDF]

Astrophysical Journal Letters, 2021
V1298 Tau is a young (20–30 Myr) solar-mass K star hosting four transiting exoplanets with sizes between 0.5 and 0.9 R J. Given the system’s youth, it provides a unique opportunity to understand the evolution of planetary radii at different separations ...

Revisiting Trans-Arctic Maritime Navigability in 2011–2016 from the Perspective of Sea Ice Thickness

Remote Sensing, 2021
Arctic navigation has become operational in recent decades with the decline in summer sea ice. To assess the navigability of trans-Arctic passages, combined model and satellite sea ice thickness (CMST) data covering both freezing seasons and melting ...

Hypersatellite and satellite transitions in cobalt

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
An accurate measurement of energy shifts and relative intensities of hypersatellite and satellite transitions in cobalt have been made. The use of radioactive ^(59)Ni, which decays mostly by the nuclear K-electron capture to cobalt and the low-probability processes of ejection of the other K-electron allowed the observation of decays among very pure ...

Hypersatellite and satellite transitions in xenon atoms

Physical Review A, 1990
Decay of double-K-shell-vacancy states in xenon atoms, created in the decay of 131Cs, was investigated. The measurements were performed with a pair of germanium detectors, a fast-slow coincidence system, and a three-parameter pulse-height analyzer. In the analysis of the two-dimensional E1-E2 spectrum, improved least-squares routines were applied.
