During the late stages of their evolution, Sun-like stars bring the products of nuclear burning to the surface. Most of the carbon in the Universe is believed...
WMAP 5-year constraints on time variation of α and m in a detailed recombination scenario
We study the role of fundamental constants in an updated recombination scenario. We focus on the time variation of the fine structure constant α, and the...
Wolf 327b: A new member of the pack of ultra-short-period super-Earths around M dwarfs
Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small (R p < 2 R ⊕) ultra-short-period...
Wolf 503 b: Characterization of a Sub-Neptune Orbiting a Metal-poor K Dwarf
Using radial-velocity measurements from four instruments, we report the mass and density of a 2.043 ±0.069 R ⊕ sub-Neptune orbiting the quiet K-dwarf Wolf 503...
Wolf-Rayet stars have been detected in a large number of galaxies experiencing intense bursts of star formation. All stars initially more massive than a certain...
Exoplanetary systems show a wide variety of architectures, which can be explained by different formation and dynamical evolution processes. Precise orbital...
WSO and the winds of massive stars: the gate to the metal-poor Local Universe
The spectrographs on-board the World Space Observatory (WSO) will provide access to the 1020-1800 Å wavelength range with unprecedented sensitivity. Previous...
