Cold super-Earths that retain their primordial, H–He-dominated atmosphere could have
surfaces that are warm enough to host liquid water. This would be due to the collision …

ABSTRACT A major goal in the discovery and characterization of exoplanets is to identify
terrestrial-type worlds that are similar to (or otherwise distinct from) our Earth. Recent results …

Theoretical physical-chemical models for the formation of planetary systems depend on data
quality for the Sun's composition, that of stars in the solar neighbourhood, and of the …

Context. Both rocky super-Earths and volatile-rich sub-Neptunes have been found
simultaneously in multi-planetary systems, suggesting that these systems are appropriate to …

We report new branching fraction measurements for 224 ultraviolet and optical transitions of
Tm ii. These transitions range in wavelength (wavenumber) from 2350 to 6417 Å (42,532 …

The energy provided in the radioactive decay of thorium (Th) and uranium (U) isotopes,
embedded in planetary mantles, sustains geodynamics important for surface habitability …

We report new branching fraction measurements for 224 ultraviolet (UV) and optical
transitions of Tm II. These transitions range in wavelength (wavenumber) from 2350-6417 …

Exoplanets orbiting distant stars have revealed to us that no one could have predicted Earth.
Many stars host planets which appear to be made of rock and iron like Earth, but sit at …
